Australia's Food Crops Face a Genetic Race Against Climate Change - Lethal Heating Editor BDA

Australia's changing climate is threatening crop productivity and 
accelerating the search for genetically resilient fruit and vegetable varieties

Key Points

Climate change will increase selection pressures favouring heat-tolerant and drought-resistant crop varieties. Genetic change will depend primarily on breeding and selection. [1] Rising carbon dioxide concentrations threaten the nutritional composition of several food crops, particularly their mineral and protein content. [3] Warmer winters threaten winter-chill requirements in apples, while extreme heat damages fruit development and quality. [4] Floods, droughts and heatwaves threaten production reliability, increasing pressure on growers and household food budgets. [6] Supermarkets and distribution networks face growing pressure to diversify suppliers and accommodate variable harvest quality. [6] Australia's National Adaptation Plan and mandatory climate reporting provide frameworks for managing agricultural risks. [7][8]

At first light, an Australian orchardist walks between rows of fruit trees, inspecting the developing crop. 

Some branches carry healthy fruit while others show signs of heat stress and uneven development. 

Each growing season brings fresh decisions about irrigation, varieties and the financial viability of the orchard.

Across Australia's agricultural regions, rising temperatures, changing rainfall and increasingly damaging extremes are altering the conditions under which food crops grow. 

Researchers and growers face an increasingly urgent task: identifying varieties capable of maintaining reliable production under conditions that increasingly challenge established agricultural practices. ^[1]

Climate Change and Crop Genetics

By 2030, Australia's principal fruit and vegetable crops will face stronger environmental selection pressures. Heat tolerance, efficient water use, resistance to disease and reliable flowering will become increasingly valuable breeding characteristics.

 These pressures affect bananas, apples, citrus, strawberries, watermelons, leafy vegetables, potatoes, tomatoes, carrots, onions, mushrooms, pumpkins, peas and beans. ^[1]

Genetic variation describes inherited differences between individual plants and crop varieties. Breeders identify useful variations through conventional crossing, field trials and molecular techniques. 

Genomic selection uses information across an organism's DNA to estimate which breeding candidates carry desirable characteristics. Australian research institutions already apply these approaches to improve heat and drought tolerance in agricultural crops. ^[2]

Elevated atmospheric carbon dioxide creates another challenge for crop quality. A 2025 meta-analysis examined 43 food crops and 29,524 observation pairs. Researchers identified widespread changes in plant nutrient composition, with zinc showing particularly substantial reductions. 

The study demonstrates that increased plant growth can coexist with declining nutritional value. ^[3]

These changes involve plant physiology and nutrient allocation rather than an automatic rewriting of crop genomes. Genetic adaptation depends on inherited variation, reproduction and deliberate breeding decisions. By 2030, breeders may introduce improved varieties, but no reliable national forecast quantifies genetic changes across every Australian horticultural crop. ^[2][3]

Orchard and Farm Productivity

Australian agriculture faces increasingly difficult combinations of heat, rainfall variability and water scarcity. CSIRO and the Bureau of Meteorology project continued warming, more extremely hot days and declining cool-season rainfall across much of southern Australia. These changes threaten growing conditions and increase pressure on irrigation supplies. ^[1]

Apple production illustrates the genetic and commercial consequences. Deciduous fruit trees require winter chilling, a period of sufficiently cool temperatures that supports subsequent flowering. Warmer winters can reduce accumulated chill, disrupt flowering and weaken fruit production. Growers may consequently favour lower-chill cultivars suited to changing regional conditions. ^[4]

Citrus faces different pressures. Higher temperatures and changing humidity can affect flowering, fruit setting, fruit size and irrigation requirements. NSW produces approximately 52 per cent of Australia's oranges. Its climate vulnerability assessments examine future suitability across important horticultural commodities and growing regions. ^[5]

Extreme heat, flash flooding and prolonged drought also threaten vegetables. Heat can interrupt pollination, reduce fruit setting and accelerate moisture loss. Excessive rainfall can damage roots, increase fungal diseases and prevent harvesting. Changing pest and weed distributions create additional demands for crop protection and farm management. ^[1][5]

Food Production and Consumer Security

Agricultural losses increasingly connect climate extremes with household food costs. Australia's experience during 2022 demonstrated the vulnerability of fresh produce supplies. Repeated flooding damaged major eastern production regions, destroyed crops and disrupted transport infrastructure. Vegetable shortages contributed to substantial increases in retail prices. ^[6]

A Senate inquiry reported that fruit and vegetable prices increased by an average of 16 per cent during the year to late 2022. Cyclone Larry had previously demonstrated similar vulnerabilities through extensive damage to Queensland's banana industry. Such events expose the financial consequences of concentrated production and disrupted distribution. ^[6]

Supply disruptions carry nutritional consequences beyond supermarket prices. Lower-income households face greater difficulty maintaining affordable access to fresh vegetables and fruit when prices rise. Reduced availability of nutrient-rich produce can compound existing dietary inequalities. Rising carbon dioxide also introduces potential nutritional losses within otherwise successful harvests. ^[3][6]

Australia's biosecurity requirements also shape its ability to respond to domestic shortages through imports. The Department of Agriculture requires permitted produce to satisfy strict pest, disease and food-safety conditions. These safeguards protect agricultural industries, although alternative overseas supplies depend on approved commodities and exporting countries. ^[9]

Supermarkets and Agricultural Supply Chains

Climate-related production instability creates commercial risks throughout Australia's supermarket supply chains. Retailers depend on predictable volumes, consistent quality and reliable transport. Heatwaves, floods and droughts can disrupt those expectations simultaneously across several growing regions. 

Buyers consequently face stronger incentives to diversify sourcing arrangements and improve supply monitoring. ^[6]

Commercial appearance standards create another vulnerability. Weather-stressed fruit and vegetables can develop irregular shapes, blemishes and variable sizes while remaining suitable for consumption. Retailers that accept a wider range of appearances can reduce unnecessary rejection and food waste. Such purchasing changes could provide growers with additional market opportunities.

Shorter distribution routes and regional procurement can also improve resilience. Australia's agricultural supply chains depend on transport corridors, storage facilities, processing infrastructure and distribution centres. Flood damage to roads and bridges can interrupt several stages simultaneously. 

Alternative transport arrangements and geographically diversified suppliers reduce exposure to individual disruptions. ^[6]

Supermarket contracts will therefore face increasing pressure to accommodate changing harvest conditions. Flexible purchasing arrangements could support farmers confronting unpredictable production volumes. However, smaller producers require sufficient bargaining power and financial security to participate. 

Transparent contracts and meaningful risk-sharing arrangements remain important safeguards for agricultural businesses.

Australian Government and Regulatory Responsibilities

Australia's 2025 National Adaptation Plan establishes a national framework for responding to significant physical climate risks. It identifies primary industries and food as one of seven priority systems. The plan emphasises evidence-based action, collaboration and protection for communities facing disproportionate climate impacts. ^[7]

The government also identifies agricultural adaptation priorities involving improved water efficiency, technological innovation, research and crop diversification. Its Regional Investment Corporation provides concessional finance for eligible agricultural businesses. The National Adaptation Plan also outlines additional support for climate resilience and agricultural productivity. ^[7]

Mandatory climate-related financial disclosure introduces another regulatory responsibility. Australia's corporate sustainability reporting regime requires eligible companies to disclose material climate risks, opportunities, emissions and governance arrangements. 

ASIC oversees compliance with the Corporations Act and applicable climate reporting standards. These requirements can improve visibility across major agricultural and grocery businesses. ^[8]

However, reporting requirements alone cannot protect Australia's food production system. Governments must connect climate assessments with practical agricultural investment, research funding and regional infrastructure planning. 

First Nations knowledge and community experience also deserve meaningful participation. Accountability requires measurable adaptation outcomes and transparent evaluation of public expenditure. ^[7]

By 2030, Australia's agricultural landscape will face greater pressure to adapt to rising temperatures, changing rainfall and increasingly damaging extremes. Genetic diversity and improved breeding will help determine which crops remain productive across changing growing regions.

The consequences extend beyond farms. Crop quality, nutritional security, supermarket prices and household food affordability all depend on reliable agricultural production. Farmers, researchers, retailers and governments share responsibility for managing these interconnected risks.

Australia now has national adaptation and corporate disclosure frameworks. Their effectiveness will depend on sustained investment, transparent accountability and practical support for growers. 

Protecting future food supplies requires action across the entire production system, from genetic research and healthy soils to supermarket purchasing policies.

Australia's Children Face a Lifetime of Heat, a Major Health Report Finds - Lethal Heating Editor BDA

Children across Australia and New Zealand already carry
a rising climate health burden that will last their lifetimes

Key Points

The eighth MJA–Lancet Countdown Oceania report finds children already suffer climate harm and face a lifetime of exposure.[1] Australian infants endured 4.6 heatwave days a year over 2016 to 2025, 66 per cent above baseline.[2] Half of 16,230 surveyed Australians aged 14 to 19 report climate worry or sadness. One in seven says it harms daily life.[1] A new indicator tracks time on Country, using Indigenous-governed data in this report for the first time.[3] Heat-related deaths carry estimated costs of US$1.49 billion a year, more than double early-century costs.[1] A children's health bill failed to become law, yet the UN climate conference COP31 offers Australia an opening.[4]

Anjali Sharma took the federal Environment Minister to court as a teenager over a coal mine expansion. 

She now leads the Climate Duty of Care campaign and cites a children's wellbeing bill that failed to pass. 

A duty of care is a legal obligation to take reasonable care to avoid harming others.^[2]

The 2026 MJA–Lancet Countdown Oceania report tracks 28 indicators across five health and climate domains. 

Forty-one experts from 18 institutions wrote the eighth annual edition. 

Domains span hazards, adaptation, mitigation, economics and political engagement.^[3]

Report overview

The report concludes that children already bear climate impacts and face a lifetime of exposure to come. 

Heatwave exposure for infants and older adults has risen substantially across both countries over the past decade. 

A heatwave is a spell of unusually high temperatures that lasts several days.^[1]

Infants in Australia endured an average of 4.6 heatwave days a year across 2016 to 2025. That figure sits 66 per cent above the 1986 to 2005 baseline. Parents for Climate chief executive Nic Seton describes that as two-thirds more heatwave days than a generation ago.^[2]

Lead author Paul Beggs ranks climate change as the century's largest health threat. He says children and young people already feel the physical and mental effects. Rising heat also limits safe outdoor activity, lowers participation and raises heat illness during exercise.^[5]

Australia holds the role of President of Negotiations at COP31, the 31st United Nations climate conference, in November. The report treats that role as a chance to place health at the centre of international climate action. Authors urge stronger commitments to cut emissions and to adapt.^[5]

Health hazards and impacts

Climate change makes hot spells more frequent and longer, which raises heatwave days for infants and older adults. An urban heat island, where built surfaces trap heat, adds to the load. Associate Professor Aditya Vyas reports Western Sydney heatwaves run 10 degrees hotter than the affluent east.^[2]

Attribution science measures how much climate change adds to a specific hazard. Across 2021 to 2025, 65 per cent of Australian heatwave days trace to climate change. Climate Councillor Andrew Watkins notes Port Augusta became the southernmost place on Earth to record 50 degrees last summer.^[2]

Countdown data show very high or extreme fire danger exposure reached 33.6 days per person across 2013 to 2022. Anxiety, post-traumatic stress disorder and depression rank among the most reported mental health problems after bushfires. The 2019 to 2020 fires caused about 450 deaths through injury and air pollution.^[6][7]

Drought ranks among Australia's most important climate extremes, with substantial effects on physical and mental health. A Curtin University study of 35,309 girls and young women aged 13 to 24 spanned 14 countries. In those low- and middle-income countries, prolonged extreme drought carried 21 per cent higher odds of sexual violence.^[6][8]

Mental health and wellbeing

The survey reached 16,230 Australians aged 14 to 19. Half reported worry or sadness about climate change and its threat to people. The authors say the threat to physical and mental health continues to grow.^[1]

About one in seven respondents, or 13.5 per cent, said climate feelings negatively affect their daily life. Separately, 49 per cent said they worry that climate change threatens people and the planet. ECOMIND co-founder Georgia Monaghan argues that government inaction, as well as climate itself, fuels young people's distress.^[2]

Today's children face decades of exposure ahead, a point that gives the report its title. The authors say climate change shapes child health through heat, severe weather, worsening environments and youth mental health strain. Climate education, advocacy and collective action can build agency, coping and hope among children, the report adds.^[4]

The survey adds a direct measure of how young people feel, which exposure statistics alone leave unmeasured. That measure sits beside indicators on hazards, adaptation, mitigation, economics and political engagement.^[1]

Adaptation and equity

New Zealand published its Health National Adaptation Plan 2024 to 2027 in October 2024. A health national adaptation plan sets how a health system prepares for climate impacts. The report says the plan lays foundations for resilience and recognises environmental and social determinants of health.^[1]

Climate services supply tailored climate data and forecasts to decision makers, including health authorities. The report rates provision to the health sector in Australia and New Zealand as advanced.^[1]

For the first time, the report tracks Aboriginal and Torres Strait Islander time on Country with Indigenous-governed data. Almost 60 per cent of adults spent time on Country between 2021 and 2025. Dr Bronwyn Wilkes, a Gundungurra woman, says an estimated 14.3 per cent wanted that time but lacked access.^[3]

Weather-related disasters displaced 32,177 people in Australia in 2024, including 25,000 through flooding in Queensland. A 2024 Deloitte study for UNICEF Australia counts over 1.4 million children and young people facing disasters annually. Associate Professor Aditya Vyas calls GP clinics and emergency departments the first line of defence in disasters.^[2]

Mitigation, economics and action

Heat-related mortality carries estimated costs averaging US$1.49 billion a year across 2021 to 2025. Inflation-adjusted, that sum more than doubles the cost at the start of the century. A net carbon price weighs pricing against fuel subsidies, and Australia's stood at minus AU$27.80 per tonne in 2024.^[1][2]

Australian healthcare-related greenhouse gas emissions generally declined from 2016 to 2023, in both total and per capita terms. Spikes around 2018 and a modest rise from 2022 to 2023 interrupt the trend. Globally, health-care emissions rose 25.5 per cent since 2016, so Australia diverges from the worldwide pattern.^[4]

Cutting emissions also delivers health co-benefits, a domain the report tracks directly. This edition shifts from electric vehicle uptake to indicators on walking and cycling. Globally, cleaner energy cut indoor air pollution deaths by an estimated 400,000 in 2023 versus 2016.^[4]

The Climate Change Amendment (Duty of Care and Intergenerational Climate Equity) Bill 2025 failed to become law. It sought to amend the Climate Change Act 2022, which legislates national emissions targets, so decision-makers weigh children's health. The report counts it among important lost opportunities, and two UN experts now question coal and gas approvals.^[2]

The 2026 MJA–Lancet Countdown Oceania report shows children carrying climate harm today and facing decades more. Heatwaves, bushfire smoke, drought and distress converge on young Australians, while heat deaths already cost US$1.49 billion annually.

A children's duty of care bill failed to pass, while a negative net carbon price effectively subsidises fossil fuels. Accountability rests with the federal decision-makers who set targets, approvals and subsidies.

COP31 offers Australia a platform to put health at the centre of negotiations. The evidence supports faster emissions cuts, stronger adaptation and child-centred policy before the next summer. Each season of delay adds to the lifetime exposure already facing today's children.

Clean Grid, Gas Gap: Western Australia's Climate Contradictions - Lethal Heating Editor BDA

Western Australia has set a 75 per cent renewable target
while methane and drought pressures intensify

Key Points

Western Australia set a 75 per cent renewable target for its main grid by 2030-31.[1] Renewables supplied 39 per cent of SWIS electricity in 2024-25, about triple the 2016 share.[2] Government-cited modelling projects an 89 per cent rise in industrial energy prices by 2032 without new initiatives.[1] Satellites recorded methane above Chevron's Gorgon plant averaging 7.8 tonnes an hour in late August.[3] Conservation Council of WA says state emissions have risen 19 per cent since 2005.[4] South West July rainfall reached 37.2 per cent of average. The Alkimos desalination plant targets a 2028 start.[5][6]

A Murdoch University researcher watched two Bunbury dolphins, Smiley and Star, strand within minutes this winter. 

Parks and Wildlife Service staff carried both animals to deeper water, where they later foraged normally. 

Population ecologist Dr Krista Nicholson says a drying climate dries estuaries, and shifting water levels may raise those risks.^[7]

Three pressures now converge in Western Australia: rapid grid change, a methane controversy and a drier, fire-prone landscape. 

Each tests state institutions in a different way. 

The evidence below shows where governance has kept pace and where gaps remain.

A New Grid Target

On 27 October, Western Australia set a formal target of 75 per cent renewable electricity by 2030-31. 

The target covers the South West Interconnected System (SWIS), the grid serving Perth and much of the South West. 

Energy Minister Amber-Jade Sanderson calls the goal a statement of intent that aims to attract private investment.^[1]

Renewables supplied 39 per cent of SWIS electricity use in 2024-25, around three times the 2016 share. The new target nearly doubles that share within five years.^[2][1]

By the end of the decade, the government has vowed to close its last state-owned coal generators at Collie. The one privately owned coal generator is also likely to close. State-owned Synergy and Water Corporation have written some of the purchase agreements underpinning new developments.^[1]

In 2012, an energy minister opened Greenough River, the nation's first large-scale solar farm, and vowed to stop there. Western Australia now accounts for half of the nation's 10 wind projects past financial close, when lenders commit funds. Construction began this month on the 470 MW Parron Maam Marang project north of Perth.^[1]

Prices, Gas and Industry

The state government cites modelling supported by Boston Consulting Group. It found industrial energy prices could rise 89 per cent by 2032 without new initiatives. The government presents the target as an affordability measure as well as a climate measure.^[1]

A Made in WA Energy Affordability Investment Program offers manufacturers low-interest loans of up to A$15 million. Firms can spend the money on solar and battery systems and equipment upgrades. Officials say the equipment upgrades let manufacturers use cheaper energy.^[1]

Sanderson calls renewables backed by storage and gas the cheapest, most reliable mix. Gas therefore keeps a firming role, supplying power when wind and solar output falls. Climate Energy Finance head Tim Buckley urges iron ore miners to follow Fortescue and decarbonise their own power.^[1]

Unions and investors back the target. UnionsWA Secretary Rikki Hendon wants secure, well-paid renewable jobs for workers who currently depend on coal and gas. Clean Energy Investor Group chief Richie Merzian calls Western Australia the third most attractive state for investment.^[1]

Methane Above Barrow Island

Independent satellite monitoring detected persistent methane clouds above Chevron's Gorgon liquefied natural gas plant on Barrow Island. The Tanager-1 satellite recorded the plumes on five consecutive passes since November last year. Observations ranged from about one to eight tonnes of methane an hour.^[3]

The latest pass, in late August, averaged about 7.8 tonnes of methane an hour. Methane is a greenhouse gas the United Nations rates 80 times more harmful than carbon dioxide. The ABC equates that rate to burning more than 110,000 kilograms of coal an hour.^[3]

The latest reading far exceeds a super-emitter event under US Environmental Protection Agency guidelines. The United Nations warned Chevron, which says satellite data carries a wide range of uncertainty. Chevron also says it is engaging with the UN Environment Programme.^[3]

A UN Environment Programme spokesperson says Chevron and the Australian Government have yet to provide formal feedback. Data Desk researcher Louis Goddard says the consistent readings suggest an operational issue near the plant's acid gas removal units. Dr Bruce Norris of the University of Western Australia estimates a few thousand tonnes may have leaked over a year.^[3]

Targets and Accountability

Conservation Council of WA director Matt Roberts says state emissions have risen 19 per cent since 2005. He adds that Western Australia remains the only state lacking an interim emissions reduction target. Roberts made those remarks as the Global Citizen NOW summit opened in Perth.^[4]

The reports reveal a jurisdictional gap. Methane sits outside Gorgon's federal approval, so the National Environmental Protection Agency referred ABC enquiries to state regulators. The WA Government concedes uncertainty about its role, while its environment department investigates.^[3]

Chevron received a similar methane notification in July last year. Carbon capture and storage, designed to bury emissions underground, has drastically underperformed at the project since 2016. Chevron also reported unknown amounts of gas seeping to Barrow Island's surface last year.^[3]

Australia helps fund the system that flagged the plumes. Carbon Mapper operates the satellite within the UN's International Methane Emissions Observatory, which lists Australia as a key donor. UNEP will update its public methane data once feedback arrives.^[3]

Dry Country, Fire and Heat

Rainfall across the South West averaged 42.05 millimetres in July, just 37.2 per cent of the long-term average. That ranked as the second-driest July on record, behind 2012. August then ran 62 per cent above average statewide.^[5][8]

Perth's A$2.8 billion Alkimos Seawater Desalination Plant reached a marine milestone in September. Tunnel boring machines completed two of Australia's longest undersea tunnels, which carry seawater in and brine out. The plant targets operation in 2028, supplying an initial 50 billion litres of drinking water yearly.^[6]

The Government activated harvest water bombers early to meet a heightened fire risk across the Wheatbelt. A two-aircraft strike team now operates from Narrogin, with two more starting in Geraldton and Esperance on 1 November. Last season, harvest fires reached Emergency Warning level, threatening lives and property.^[9]

Doctors for the Environment's WA branch reports more than 7000 heat-related hospital admissions and 300 deaths in a decade. The group urges the Cook Government to stop approving gas projects and cut emissions. The doctors warn the state health system will struggle with more heatwave patients.^[10]

Western Australia has set a clear direction for its main electricity grid. A 75 per cent renewable target, paired with coal closures, gives investors and workers a measurable goal. Industry loans aim to cushion manufacturers from projected price rises.

Accountability remains less settled. Gorgon's methane plumes, a regulatory gap and a missing interim target leave gas emissions without a clear owner. Chevron cites uncertainty in satellite data, which makes closer measurement essential.

Dry winters, harvest fires and heat illness show the cost of delay. The next test is whether the state matches its grid ambition with enforceable limits on methane and economy-wide emissions.

From Flood to Fire: South Australia's Climate Whiplash - Lethal Heating Editor BDA

South Australia faces a hotter and drier summer
after its wettest winter in almost five decades

Key Points

The Country Fire Service opened the Fire Danger Season on 15 October in three northern districts, earlier than last year.[1] September's mean maximum temperature reached 27.5°C, 3.86°C above the 1961–1990 average and the third-warmest September since 1910.[2] South Australia recorded its sixth-wettest winter on record and its wettest since 1978.[3] The World Meteorological Organization forecasts record Pacific sea-surface temperatures from October to December, with the El Niño peaking around December.[4] Salinity and water levels most strongly shape Coorong phytoplankton, which sets the risk of harmful algal blooms.[5] Governments committed $102.5 million to an Algal Bloom Summer Plan that funds shellfish reefs and a dedicated research office.[6]

Hail and damaging winds swept across Adelaide on Sunday 11 October, toppling trees onto cars and blocking roads. 

Several storms crossed the state that afternoon and mostly cleared by 9 pm. Fallen trees accounted for most calls to the State Emergency Service.^[7]

That storm followed the wettest winter in South Australia since 1978 and a record-warm September in Adelaide. Fire authorities have also advanced the Fire Danger Season across the north. 

This investigation examines fire, water, coastal and algal threats converging on a state that spent winter sodden.

Fire and Heat

The Country Fire Service (CFS) opened the 2026–27 Fire Danger Season on 15 October in three northern districts. 

Flinders, North East Pastoral and North West Pastoral start earlier than last year because of elevated fuel loads. Vegetation curing, the drying of grass until it burns readily, adds to the risk.^[1]

Eastern Eyre and West Coast again start on 15 October, and Lower Eyre Peninsula follows on 15 November. Riverland, Murraylands, Lower South East and Upper South East begin on 1 November. A permit is required for most burning during the season.^[1][8]

Adelaide (West Terrace) recorded its highest September mean temperature on record. Across the state, the mean maximum reached 27.5°C, which is 3.86°C above the 1961–1990 average. That ranked third-warmest for any September since 1910, while rainfall finished 33% below average.^[2]

Emergency Leaders for Climate Action put the annual cost of bushfires at about $6 billion. Single major events, such as Black Summer, cost almost $30 billion. About 5.6 million households, roughly half the nation, face bushfire exposure.^[9]

Drought and Water Security

El Niño is a warming of tropical Pacific surface waters that shifts rainfall and temperature patterns across Australia. The World Meteorological Organization forecasts record sea-surface temperatures in the central and eastern tropical Pacific from October to December. The event should peak around December.^[4]

El Niño raises the likelihood of hotter, drier conditions across much of southern Australia. Other climate drivers shape local outcomes, as this wet winter inside an El Niño year shows. The swing from soaked ground to dry spring heightens fire risk.

South Australia sits at the downstream end of the Murray-Darling Basin, where upstream decisions shape river flows. The Basin Plan is the national framework that limits water extraction and returns water to the environment. The state government's May 2026 submission to the Basin Plan review insists on full recovery against every target.^[10]

The submission points to incomplete water recovery in the southern Basin. Incomplete recovery leaves downstream communities and ecosystems with less margin as El Niño intensifies. The review outcome will show whether recovery targets match a hotter climate.^[10]

Coorong and Algal Blooms

The Coorong lies on Ngarrindjeri Country at the mouth of the River Murray. Phytoplankton, the microscopic organisms that drift in its water, anchor the food web. Pipis, mussels, insects and small fish all eat them.^[5]

A Flinders University-led study found salinity and water levels most strongly shape Coorong phytoplankton. Climate-driven shifts in freshwater flows therefore reorder which species dominate. Salinity, the concentration of dissolved salt, swings sharply between drought and flood.^[5]

Harmful algal blooms follow different pathways. Drought-driven, high-salinity conditions raise the risk of dinoflagellate blooms, a group of single-celled plankton. High-nutrient, low-salinity conditions favour cyanobacteria, the blue-green algae.^[5]

The state and federal governments announced a $102.5 million Algal Bloom Summer Plan. It funds large-scale and community shellfish reef restoration and trials of bloom-management methods in controlled waterways. A new Office for Algal Bloom Research will undertake long-term studies of bloom events.^[6]

Coasts and Storms

Climate Ready Coasts is the state program that improves coastal management and accelerates coastal hazard adaptation planning. A coastal hazard is any process, such as erosion or storm surge, that threatens shoreline property and ecosystems. Planning of this kind sets protection priorities before storms and erosion force the decision.^[6]

Higher seas raise the baseline for storm surge, so the same storm reaches further inland. Erosion removes sand from beaches that buffer coastal suburbs. Both pressures build slowly and then arrive in single events.

Around four in five State Emergency Service calls on Sunday 11 October involved fallen trees. Trees blocked roads and fell onto vehicles across Adelaide. Damage spread across metropolitan Adelaide rather than the coast alone.^[7]

South Australia's 2025 Transport Strategy includes actions to weigh climate impacts in key transport decisions. The strategy also aims to strengthen transport resilience against major weather events. Storm-blocked roads show where that aim meets daily travel.^[6]

Adaptation and Policy

The state's Climate Change Resilience and Adaptation Actions outline government-led steps to prepare for climate impacts. The actions support efforts across all levels of government, business and the community. The document covers coasts, transport and algal bloom response, among other areas.^[6]

The 2024 Statewide Climate Change Risk and Opportunity Assessment will inform a review and update of those actions. That sequencing puts evidence ahead of revised commitments. Updated actions should reflect the latest evidence on heat, rainfall and sea level.^[6]

The state describes the actions as only a portion of broader efforts across governments, business and communities. That framing leaves the public without a single measure of total delivery. Independent tracking would close that gap.^[6]

Several decisions will shape the response to this summer's risks. The Basin Plan review, the adaptation actions update and algal research funding will test whether governance matches the risk. Frontline communities, including Ngarrindjeri people on the Coorong, carry the consequences of delay.

South Australia enters summer with a wet winter's growth drying under early heat. Fire authorities advanced the season, yet fuel and weather leave a narrow margin. The early declaration shows agencies reading the same evidence that scientists publish.

Water, coastal and algal risks compound the fire threat. The Basin Plan review, Coorong research and the algal bloom plan each depend on governments delivering their commitments. Delay in any one area increases pressure on the others.

Accountability now rests on published milestones, transparent funding and measurable outcomes. Bureau of Meteorology data and the state's own risk assessment supply the benchmarks. Residents deserve to see which agency owns each action and by when.

A $57 Billion Climate Change Warning: Victoria's Exposure Outpaces Its Spending - Lethal Heating Editor BDA

Heat, fire and rising seas have unmasked Victoria's adaptation gap
with funding trailing the scale of the risk

Key Points

Victoria’s September 2026 rainfall fell 59 per cent below average while maximum temperatures ran 2.68°C above it. Those conditions raise drought, fuel dryness and bushfire concern.[1] Heat drives 4,574 hospital admissions and 10,920 emergency visits each year in Victoria. Human-induced climate change lifted heat-related hospitalisations by 27.25 per cent.[2] More than $57 billion of government-owned or regulated infrastructure faces climate risk from a $318 billion asset base.[3] On current settings, the Victorian Marine and Coastal Council estimates $337 billion in coastal damage by 2100.[4] The 2025 to 2026 budget allocated $264 million to adaptation, while extreme weather has cost $2.7 billion a year on average.[3] Victoria approved the $1 billion Golden Beach Gas Project, with production from 2028 and storage from 2029.[5]

Beneath Port Phillip Bay, kelp forests have declined by a reported 90 per cent. 

Warming waters also draw tropical species south along the Victorian coast. 

Victoria’s climate future has arrived in measurable form.^[6]

Health data, infrastructure audits and weather records now tell a consistent story. 

This investigation examines the evidence, the agencies responsible and the gaps in accountability. 

Five themes follow: heat and fire, health costs, infrastructure, coasts and adaptation policy.

Heat and Fire Before Summer

The Bureau of Meteorology recorded September 2026 rainfall in Victoria 59 per cent below the 1961 to 1990 average. 

That made it the sixth-driest September since 1900. 

Mean maximum temperatures ran 2.68°C above average, the fourth-warmest on record.^[1]

Dry soils and hot days heighten drought stress, the condition in which plants lack enough water to function. 

They also dry the fuel that feeds bushfires, including leaf litter, bark and grass. 

That combination heightens concern about an unusually dangerous fire season.^[1]

El Niño, a warming of the tropical Pacific that shifts rainfall patterns, shapes Victoria’s 2026 to 2027 outlook. 

Whether those conditions deliver major bushfires and heatwave deaths remains the central test for emergency services. 

Hospitals and responders carry the strain if the season delivers extremes.^[1]

Health experts warn the coming summer could produce record heat-related deaths. Risks include heart attacks, worsened chronic illness, mental-health impacts, stillbirth and premature birth. 

Older homes with weak thermal performance leave residents of Melbourne’s hotter suburbs especially exposed.^[7]

The Measured Health Burden

A Monash University-led study analysed more than six million hospital admissions and emergency visits across 460 communities. Professors Yuming Guo and Shandy Li led the research, which covered hot seasons from 2014 to 2019. 

Heat accounted for 4,574 hospital admissions and 10,920 emergency department visits annually.^[2]

Those hospital visits cost the health system more than $30 million every year. Risks proved highest among women, in rural areas and in northern communities. The findings give planners a map of where heat harms most.^[2]

Researchers estimated that human-induced climate change increased heat-related hospitalisations by 27.25 per cent. Emergency department visits rose by 16.46 per cent from the same cause. Urban areas proved more sensitive, with climate change contributing 31.28 per cent of heat-related hospitalisations.^[2]

Heat therefore qualifies as a public-health emergency rather than a routine weather event. The burden concentrates in communities with less cooling, poorer housing and higher exposure. It will grow as hot days become more frequent.^[7]

Infrastructure Under Threat

Infrastructure Victoria, the state’s independent adviser, produced the first statewide map of climate risk to government-owned or regulated assets. It assessed $318 billion in assets against seven extreme weather events. 

More than $57 billion of that value faces damage or disruption.^[3]

Exposure rises by nearly 25 per cent over the next 40 years. Bushfire risk grows from more than $23 billion to over $30 billion by 2070. Extreme heat exposure climbs from nearly $11 billion to nearly $26 billion.^[3]

Flooding already threatens more than $22 billion of infrastructure, and roads carry the highest value at risk. Infrastructure Victoria urges funding for high-priority, cost-effective adaptation, including foamed bitumen stabilisation to protect roads from flooding. That technique strengthens road bases so they resist water damage.^[8]

Highest-risk roads include those around Melbourne and central Victoria, plus corridors toward Wodonga and Traralgon. Rail risk concentrates around Melbourne, Geelong and northern Victoria, while energy risk centres on Mildura, the Latrobe Valley and Portland. 

Health facilities in Bendigo, Swan Hill, Mildura and Melbourne’s south-east also rank among the highest-risk sites.^[3]

Coasts and Planning Under Pressure

The Victorian Marine and Coastal Council warns that the entire coastline faces escalating risk. Storm surge, a storm-driven rise in sea level, joins erosion and coastal flooding as hazards. 

On current settings, damage to land and property could reach $337 billion by 2100.^[4]

A Port Phillip coastal hazard assessment found flood threat rises significantly once sea levels climb beyond 0.5 metres. At 1.1 metres, about a quarter of the municipality’s land would fall within the hazard extent. Planners treat those thresholds as decision points for land use.^[4]

Inverloch, Port Fairy, Queenscliff, Point Lonsdale and Apollo Bay already report major coastal change. These towns show the hazard operating as a present condition rather than a projection. Each town sits within the coastline the Council describes as facing escalating risk.^[4]

Planners and infrastructure advisers argue Victoria must decide explicitly where to protect, retrofit, redesign or retreat. Retreat means the planned withdrawal of people and assets from high-risk locations. 

The state has improved some settings, including statewide flood mapping responsibility and bushfire-specific building standards.^[4]

The Adaptation Gap and Policy Contradictions

Victoria’s climate has warmed by 1.4°C since pre-industrial times. Cool-season rainfall has fallen by more than 10 per cent over 30 years compared with 1961 to 1990. The state’s science report projects further warming, drier cool seasons and worsening heatwaves, drought, bushfire and sea-level hazards.^[9]

Agriculture shows the strain in several sectors. Reported impacts include heat-damaged avocados, earlier grape harvests, lower grain yields, livestock heat stress and reduced egg production. Warming waters shift species distribution and erode kelp forests, the underwater canopies that shelter marine life.^[6]

Victoria has spent about $2 billion reducing emissions. The 2025 to 2026 budget allocated $264 million to adaptation, about one-third tied to bushfire recovery. Extreme weather cost the Victorian economy an average of $2.7 billion a year in the decade to 2016.^[3]

The Victorian Government approved the production licence for the $1 billion Golden Beach Gas Project off Gippsland. Production can begin from 2028 and storage from 2029, lifting state gas storage capacity by about 70 per cent. Environment groups frame the approval as another fossil-fuel project cleared ahead of the hot season.^[5][10]

Victoria’s evidence base now spans hospital wards, asset registers and coastlines. Each dataset points to exposure that exceeds the state’s adaptation effort. The science, the costs and the highest-risk locations are all documented.

Accountability rests with the agencies and ministers who set budgets, planning rules and building standards. A $264 million adaptation allocation sits beside $57 billion of exposed infrastructure and a new gas production licence. Those choices determine who bears the cost when heat, fire and flood arrive.

Decisions on where to protect, retrofit, redesign or retreat must precede the next disaster. The coming summer will show whether Victoria’s institutions act on the evidence already in hand. Public scrutiny of budgets and approvals will determine whether adaptation keeps pace with risk.

Climate Change, Floods, Heat, and a Warming Reef Test Queensland's Planning Rules - Lethal Heating Editor BDA

Record October rain has opened Queensland's severe weather season
while heat and Reef risks mount

Key Points

Nambour and Beerburrum broke October rainfall records, and eight stations north of Brisbane exceeded 300 mm in 48 hours.[1] Queensland has warmed 1.5°C since 1910, and the state's risk assessment ranks heatwaves as its deadliest hazard.[2] September's state-average maximum temperature ran 2.81°C above the 1961 to 1990 average, the sixth warmest September since 1910.[3] The Reef Authority says a moderate marine heatwave is possible from December 2026.[4] Queensland has the most at-risk coastal properties in Australia at 93,157, with projected losses of $214.5 billion by 2100.[5] Queensland is Australia's most disaster-prone state, and one analysis puts historical disaster costs at $50 billion to $70 billion.[6]

Floodwater cut roads across Caboolture, north of Brisbane, on the morning of 22 October. 

Rain fell at up to 170 mm in three hours, and 14 schools closed. 

State Emergency Service crews answered hundreds of calls.^[7]

The deluge landed amid above-average heat, a looming Reef warning and a live debate about planning rules. 

This article examines five linked pressures: sudden flooding, urban heat, Reef temperatures, seasonal risk and financial exposure. 

Each pressure exposes gaps between known hazards and the policies that govern them.

A Storm That Outran the Forecast

Flash flooding is rapid inundation that follows intense rain within hours, often giving communities little warning. 

At least eight weather stations in the Pine and Caboolture river catchments recorded more than 300 mm over 48 hours. 

Weather tracking site Weatherzone supplied the data to SBS News.^[1]

Nambour broke its October record, reaching 401 mm against the old mark of 370.6 mm. Beerburrum topped its previous record of 311.5 mm, reaching 354.2 mm. 

The Bureau of Meteorology had flagged Thursday as the wettest day, yet the severity proved unprecedented.^[1]

Dr Michael Barnes of Monash University says thunderstorms delivering 200 mm within 24 hours arise from highly localised processes. Small errors can shift a storm's forecast path or location. Forecasting itself has improved, with a seven-day forecast now matching the accuracy of a two-day forecast 40 years ago.^[1]

Climate change complicates the picture, Barnes says, because thunderstorms are driving intensifying daily and sub-daily rainfall extremes. Dr Andrew King says El Niño, a Pacific warming pattern, raises heat odds while other drivers shape outcomes. 

Dr King, from the University of Melbourne, says climate change continues amplifying extremes in the background.^[1]

Heat Becomes a Planning Question

Queensland's average temperature has risen 1.5°C since records began in 1910, according to government reporting. The state's heatwave risk assessment ranks heatwaves as responsible for more deaths than any other natural hazard. 

The North Queensland Conservation Council joined a petition urging the state to list heat as a natural hazard.^[2]

The draft State Planning Policy, the state document setting land-use priorities for councils, is now open for consultation. It names the reduction of urban heat islands as a key planning priority. Urban heat islands are built-up areas where concrete, roofs and walls trap heat.^[2]

Nicole Bennetts of the Planning Institute of Australia says legislation lacks mandates requiring developers to reduce heat. Repeated hot days can lift felt temperatures in built-up areas from 35°C to 40°C or higher, she says. Crystal Falknau warns that brick homes built for air conditioning become ovens when power fails.^[2]

Jarrod Bleijie, Minister for State Development, says the policy has stood unreviewed since 2016 and previously omitted heat entirely. Whether the final policy lists extreme heat as a natural hazard remains open. 

Architect James Davidson argues the National Construction Code must adapt, because passive design keeps homes liveable when power fails.^[2]

A Reef Waiting on Summer

The Great Barrier Reef Marine Park Authority reports slightly cooler sea surface temperatures across the Marine Park in September. Bureau of Meteorology long-range forecasts show temperatures rising, with a moderate marine heatwave possible from December 2026. 

A marine heatwave is a prolonged spell of unusually warm seawater.^[4]

Rainfall across Reef catchments is likely to run below average from October to December. More than 70 Traditional Owner groups hold Land and Sea Country across the Marine Park and its catchment area. The Authority calls their monitoring, compliance and stewardship essential to protecting the Reef.^[4]

Researchers from Monash University and the University of Melbourne analysed Reef weather data spanning 1996 to 2024. They studied doldrums, spells of weak winds, reduced cloud and dry air that let heat accumulate in Reef waters. 

Monash researcher Dr Lara Richards says lingering doldrums prolong ocean heating and can produce rapid temperature rises.^[8]

Bleaching, the loss of colour when stressed corals expel their algae, can follow that heat build-up. Richards points to the Lismore floods, where one low-pressure system drew moist air toward the east coast. The same circulation can steer dry air north towards the Reef.^[8]

A Season Built for Extremes

Queensland's severe weather season runs from October to April, bringing a heightened risk of storms, cyclones and floods. The Bureau of Meteorology expects this season to unfold against a strong El Niño and record warm global temperatures. 

Senior Meteorologist Laura Boekel says spring and summer will likely run hotter than usual, lifting heatwave risk.^[9]

From October to December, the east coast, including southern Queensland, faces the highest risk of severe thunderstorms. Far North Queensland joins that risk as the northern wet season begins in October. Queensland typically averages three to four tropical cyclones per season, with associated flood risk.^[9]

September delivered an early signal of the heat ahead. Queensland's area-averaged mean maximum temperature reached 31.5°C, which sat 2.81°C above the 1961 to 1990 average. That ranks as the sixth warmest September since 1910 and the highest since 2017.^[3]

Authorities urge households to prepare early, and the Bureau supported the Get Ready Queensland launch in October. Boekel says severe weather can develop quickly and threaten lives and property. Storm, flood, cyclone and heatwave risks share the same months, so communities face overlapping threats.^[9]

The Bill Written Into Property and Budgets

The Climate Council's Rising Seas, Rising Bills report finds Queensland has the most at-risk properties, at 93,157. It projects $214.5 billion in Queensland losses by 2100, split almost evenly between land use and property. The Gold Coast alone faces $84.4 billion, the most exposed urban area in Australia.^[5]

Sunshine Coast Council says its own flood mapping differs from the Climate Council modelling. The council acknowledges the region must prepare for more coastal inundation, erosion and other climate impacts. 

Report co-author Andrew Watkins lists parts of Noosa, Mooloolaba, Maroochydore and Caloundra among vulnerable low-lying sandy coasts.^[10]

A RenewEconomy analysis calls Queensland the most disaster-prone state in Australia. It estimates historical disaster costs at $50 billion to $70 billion and expects costs to outgrow the economy. The analysis also warns that reliable disaster cost data remains scarce.^[6]

Three milestones will test the response before April. Cyclone and flood risk builds through the northern wet season, and Reef heat stress could rise from December. Consultation on the State Planning Policy will show whether extreme heat earns formal hazard status.^[9][4][2]

Queensland faces linked hazards that arrive faster than the policies meant to manage them. Record October rain, a hot September and a warming Reef share rising exposure to climate extremes. The evidence from forecasters, scientists and planners points in one direction, and preparation must match exposure.

Governance gaps stand out. The planning policy stood unreviewed for a decade, and councils and researchers map flood risk differently. Reliable disaster cost data remains scarce, which complicates budgeting and adaptation planning.

Consultation on planning rules, Reef decisions and disaster funding will show whether authorities act before the costs arrive. 

Meanwhile, households on floodplains, coastlines and heat-trapping suburbs carry the risk.
