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.

Heat and Drought Push New South Wales Toward a Perilous Climate Baseline - Lethal Heating Editor BDA

Record winter warmth and a parched September have pushed NSW
into summer with rising heat and fire risk

Key Points

September 2026 delivered NSW’s fourth-driest September since 1900, with rainfall 80% below average.[1] Winter 2026 ranked as the warmest on record for NSW, at 1.81°C above the 1961–1990 average.[2] The share of Central Tablelands land in the Drought category jumped from 0.4% in August to 10.9% in September.[3] Climate-fuelled bushfires could cost Australia more than $181 billion over 30 years, averaging $6 billion a year.[4] The NSW Government accepted all nine Heat Stress Spotlight Report findings and promised a seasonal heat plan for 2027.[5] NSW has warmed 1.4°C since 1910, and sea level at the coast rose 12 cm between 1991 and 2023.[6]

On 25 September, Menindee reached 37.0°C, the hottest reading in NSW that month. 

Mudgee Airport collected 2.4 mm of rain across the entire month against an average of 54.3 mm. 

That total equalled about 4% of its usual September rainfall.^[1]

Those readings point to a pattern rather than a freak month. 

Record winter warmth, drying soils and rising fire costs now converge on a state still building its heat defences. 

This investigation examines the evidence, the communities exposed and the accountability gaps in the official response.

September Brings Heat and Almost No Rain

NSW area-averaged rainfall totalled 28.1 mm in September, 80% below the 1961–1990 average. 

Area-averaged figures merge gridded station readings into one statewide value for comparison with the long-term average. 

The result ranks as the fourth-driest September since 1900.^[1]

Parts of the Central Tablelands and neighbouring districts recorded their lowest September rainfall since 1900. 

Dubbo Airport collected 0.4 mm, about 1% of its September average. Dunedoo and Merriwa each recorded 0.0 mm for the month.^[1]

Heat compounded the dryness, with Mungindi’s September days averaging 30.5°C, or 5.2°C above normal. The area-averaged mean maximum temperature reached 25.0°C, 4.41°C above average and the third-warmest September since 1910.^[1]

Sydney’s Observatory Hill logged six straight days above 23.0°C, the earliest such September run in a record starting in 1859. Albion Park recorded its warmest September night on record, at 18.7°C. Norah Head reached 34.3°C on 21 September, a September record for that site.^[1]

A Warm Winter Sets the Stage

Winter 2026 became the warmest on record for NSW, in a series starting in 1910. The area-averaged mean temperature of 12.0°C sat 1.81°C above the 1961–1990 average. That margin beat the previous record of 1.76°C from 2023.^[2]

Rain fell unevenly across the state. Inland districts received above-average totals, and far-west sites including Tibooburra Airport had their wettest winter on record. Most coastal areas, apart from the Northern Rivers, finished below average.^[2]

Albion Park collected 23% of its winter average rainfall, the lowest on record there. Penrith Lakes recorded 27%, also the lowest. Statewide averages therefore mask sharp local deficits, particularly across Sydney’s west and the Illawarra.^[2]

Flash drought describes rapid dryness that heat and low rainfall drive within weeks, leaving little time to prepare. The NSW Combined Drought Indicator blends soil water, plant growth and rainfall data. Central Tablelands land in its Drought category rose from 0.4% in August to 10.9% in September, including Mudgee and Rylstone.^[3]

Fire Costs Climb Toward Summer

Former senior fire and emergency leaders released Prepare or Pay through Emergency Leaders for Climate Action on 22 October. ConnellGriffin modelling puts bushfire costs at more than $181 billion over 30 years. That averages $6 billion a year.^[4]

Fire seasons now run 21% longer than in 1979, the report finds. Major fires now strike every three to four years. Longer seasons shrink the windows for hazard reduction burns and limit interstate help.^[4]

The report records a fall of 10,336 firefighting volunteers between 2019 and 2023–24. Paid positions grew by only 433 over the same period. Fire crews are doing more with less, the report warns.^[4]

The Black Summer fires burnt about 45% of the Snowy Valleys local government area in 2019–20. In that area the fires killed one person and destroyed almost 200 homes. Some houses remain unrebuilt years later, leaving recovery unfinished as another fire season opens.^[7]

Heat Stress Moves Into Policy

The Net Zero Commission, an independent statutory agency, published its Heat Stress Spotlight Report on 21 April 2026. The report sets out nine findings across five action areas. Finding 1 urges a coordinated seasonal heat response plan that promotes early preventative action, health system readiness and workforce planning.^[8]

The Commission called extreme heat Australia’s most deadly yet most preventable natural disaster. Older people living alone, infants, outdoor workers and residents of poorly designed social, Aboriginal and rental housing face greatest risk. Targeted action for those groups can prevent much of the harm, the Commission argues.^[9]

The NSW Government responded this month, accepting all nine findings. It promised a seasonal heat response plan in 2027 and better methods to track heat-related deaths. That commitment answers Finding 4, which asked NSW Health to track, collect and publish data on heat-related deaths and illnesses.^[5][8]

Other findings target planning rules and SafeWork NSW regulations. The Commission wants development controls to address thermal safety and businesses to hold heat stress plans. The Minister for Climate Change, Penny Sharpe, said the government had proposed planning policy changes to reduce heat impacts.^[9]

Baselines, Money and Delivery

NSW average land temperatures have risen 1.4°C since national records began in 1910. Rising temperatures drive more hot days and severe fire weather days. Sea level rose 12 cm between 1991 and 2023, and projections reach up to one metre by 2100.^[6]

The Net Zero Commission’s 2026 Annual Progress Report finds adaptation efforts trailing the scale of the challenge. It calls for stronger governance, clearer roles and accountability, and timely delivery of commitments. It also urges better-targeted adaptation investment, backed by a long-term financing strategy across levels of government.^[10]

Prepare or Pay links resilience spending to economic returns. The report finds better fire preparation would save thousands of jobs each year. Early investment therefore protects workers and local economies as well as homes.^[4]

Section 20 of the Climate Change (Net Zero Future) Act 2023 let the Commission report on its own initiative. The Minister must publish a response within six months. That deadline gives the public a date against which to measure delivery.^[8]

September 2026 compressed several slow trends into one month. Record winter warmth, a parched spring start and rising fire costs now overlap across NSW. Each pressure reinforces the others and compounds the risk for exposed communities.

Governments hold the data and the legal duty to act. The seasonal heat plan promised for 2027 will test whether accepted findings become funded programs. Clear ministerial responsibility, public death tracking and timely delivery would show whether the response matches the evidence.

Frontline communities carry the exposure today, from drought-affected tablelands districts to renters in poorly designed housing. Firefighting crews face longer seasons with fewer volunteers and only modest growth in paid staff. Adaptation that matches the scale of the evidence remains the measure of NSW’s response.

Hotter Summers, Fewer Birds: Australia's Threatened Species Face a Policy Gap - Lethal Heating Editor BDA

Climate change is the biggest threat to Australia’s endangered birds

Key Points

Birds at semi-arid New South Wales sites died three times faster in a very hot summer than a mild one.[1] Climate change now carries the heaviest threat load for threatened birds. Knowledge of how to manage it met just 3 per cent of need in 2020.[2] Models project that 101 terrestrial and inland water bird taxa will lose their climate space by 2085.[3] Marine heatwaves in 2023 and 2024 killed an estimated 629,000 seabirds, including two shearwater species.[4] Saltwater intrusion and prolonged flooding threaten the sedge wetlands that support northern magpie geese.[5] Australians who want extinctions avoided prefer managing wild populations where they live over captive breeding.[6]

Researchers photographed a dehydrated Jacky Winter in South Australian mallee woodland the morning after a 47°C day. 

Within 24 hours of a record 49°C in 2019, 29 per cent of studied adults vanished. Scientists presumed them dead.^[1]

A national assessment ranks climate change as the biggest threat to Australia’s endangered birds, ahead of invasive species. 

Threat load sums the weighted impact scores of every pressure on a group of birds. 

The Action Plan for Australian Birds 2020 assesses 188 species or subspecies, about one in six, as nationally threatened.^[2][7]

Heatwaves and Extreme Temperatures

Citizen scientists have monitored 22,000 birds of 37 species at two semi-arid New South Wales sites since 1986. 

Survival reached 86 per cent in a mild summer that stayed at or below 38°C. 

A hot summer with 30 days above 38°C cut survival to 59 per cent.^[1]

Projections show days above 38°C at least doubling at those sites by 2104. Even rapid emissions cuts, holding warming near 1°C, lower annual survival from 63 to 43 per cent. Warming of 3.7°C this century cuts survival to 11 per cent.^[1]

Near 35°C, Jacky Winters climb the tallest trees for cooling wind, then pant, which risks fatal dehydration. Above 40°C they shelter in thermal refuges, meaning cool tree-base hollows, for up to eight hours. That halts foraging and drains body mass.^[1]

Hollows at tree bases proved significantly cooler than every other measured location. The best hollows occur only in the largest eucalypt mallees. All 41 egg clutches and 21 nestling broods exposed to air above 42°C died.^[1]

Drought, Fire and Habitat Loss

Drought, fire and heat head the list of individual pressures on threatened birds. Longer or more frequent droughts carry 10.3 per cent of total potential threat impact. Intensified fire carries 10.1 per cent, and rising temperatures and heatwaves carry 7.7 per cent.^[2]

Altered fire regimes, meaning shifts in fire frequency, intensity and extent, carry 11.6 per cent of threat load within Australia. Black Summer, the 2019 and 2020 bushfires, worsened the status of 26 species or subspecies, 16 on Kangaroo Island. Researchers also tie fire risk to the end of First Peoples fire management and to flammable exotic grasses.^[2][7]

On Kangaroo Island, high-intensity fire burnt over half the habitat of some endemic taxa. Losses ran so deep that some taxa qualified as threatened solely because of the fires. CSIRO researchers urge fire management that protects large trees, because their hollows serve as thermal refuges.^[1][2]

Climate change and altered fire regimes jointly supply nearly a third of threat load. They affect 89 per cent of taxa within Australia. Knowledge of how to manage climate threats met just 3 per cent of need in 2020.^[2]

Species Distribution and Extinction Risk

Models project 101 terrestrial and inland water bird taxa, meaning species and subspecies, will lose their climate space by 2085. Climate space means the range of climatic conditions that suits a taxon. Birds confined to Cape York, the Wet Tropics, the Top End and the arid zone rank as most vulnerable.^[3]

In Queensland’s Wet Tropics, cool-adapted birds retreat uphill as temperatures rise, creating an “escalator to extinction”. Annual surveys at 1,770 sites from 2000 to 2016 recorded rapid declines that tracked model predictions. Fernwren, Mountain Thornbill and Atherton Scrubwren have worsened in status as higher ground runs out.^[2][7]

Of the 188 threatened taxa, 23 qualify as Critically Endangered, 76 as Endangered and 89 as Vulnerable. Three birds listed as possibly extinct in 2010 now count as extinct. Climate change lifted its share of total threat load from 17.3 to 20.8 per cent between 2010 and 2020.^[2][7]

Fifty-five terrestrial taxa face more frequent or intense fires. Small island taxa rank highest for combined exposure and sensitivity to climate change, followed by marine and shoreline taxa. Yet a substantial share of threatened birds faces neither exposure nor sensitivity.^[3]

Seabirds, Coasts and Wetlands

Sixteen marine bird taxa breed at sites where models predict productivity falling at least 10 per cent. Marine productivity measures how much food the local ocean supplies. A small group of beach-nesting and saltmarsh birds also faces sea-level rise.^[3]

A marine heatwave, meaning a prolonged spell of unusually warm seawater, hit eastern Australia in 2023 and 2024. Researchers estimate those heatwaves killed 629,000 seabirds, including two Australian shearwater species. Most birds die at sea, so beach counts capture only a fraction of the toll.^[4]

Magpie geese depend on sedge wetlands across tropical northern Australia. Saltwater intrusion from sea-level rise and prolonged flooding after heavier rain could change those sedge plants. Researchers propose buffers at key wetlands to slow the saltwater.^[5]

Modelling shows marginal habitat loss in magpie goose food-plant wetlands under 1.4 metres of sea-level rise. Multi-metre rises produce large-scale losses, and the data miss fine-scale intrusion through channels and eroded levees. Researchers urge monitoring of the annual Indigenous harvest, because continued sustainable harvest depends on careful wetland management.^[8]

Conservation, Adaptation and Research

Researchers estimate managing the 396 most exposed or sensitive bird taxa would cost $18.8 million a year. That equals about $47,700 per taxon each year over the next 50 years. Monitoring leads the urgent actions, while refugia (areas that stay habitable) and captive breeding may eventually cost far more.^[3]

Eradicating introduced mammals from Macquarie Island cut the total threat load on Australian threatened birds by 5 per cent. Habitat protection and restoration, particularly on islands, and longline fishing controls also delivered measurable benefit. Published guidance on easing heat and drought effects on threatened birds remains virtually absent.^[2]

Threatened species funding in the decade to 2020 reached less than one-tenth of the estimated requirement. Taxa with recovery plans matched taxa lacking plans on the share of management need met. Only eight of the federal threatened species strategy’s 22 priority birds rank in the top 20 for threat or need.^[2]

Of surveyed Australians, 80 per cent want extinctions avoided. That group prefers managing wild populations where they live over captive breeding. More than 60 per cent of respondents accept conservation managers deciding strategy rather than local communities or the public.^[6]

Climate change now outranks every other threat to Australia’s threatened birds. The evidence spans desert mallee, upland rainforest, ocean colonies and tropical wetlands. Heat, drought and fire act on every one of those habitats.

Governance has trailed the science. Funding, knowledge and priority-setting all fell short of the scale of loss. Accountability for that gap rests with the governments that set the strategy and fund the response.

Practical answers exist. Governments can fund monitoring, protect large trees and refuges, restore habitat, control invasive species and plan for climate refugia. Australians have shown support for protecting wild populations where they live, which gives governments a clear mandate.

As Australia Heats Up Climate Change Reaches the Family Pet - Lethal Heating Editor BDA

Hotter summers and worsening disasters
are putting Australian dogs and cats at growing risk

Key Points

A 20-year New South Wales study found dog mortality risk rose 0.6% per degree above 25°C and 9.5% on days above 32°C.[1] Asphalt can exceed 50°C when the air reaches 25°C, putting pets at risk of paw burns.[2] Overnight temperatures above 25°C stop animals shedding the day’s heat, raising heat stress across consecutive hot days.[3] Researchers expect heat and floods to aid parasites, including ticks, fleas and heartworm.[4] Western Australian evacuation centres generally exclude pets other than recognised assistance animals.[5] The Bureau of Meteorology expects tropical Pacific warmth to peak around November or December and persist into autumn 2027.[6]

On a 25°C afternoon, suburban asphalt can exceed 50°C. 

Dogs cross that surface barefoot, with paw pads centimetres from the heat. 

RSPCA Australia lists burns among the injuries that rising air temperatures bring to pets.^[2]

Heat, disaster and disease now converge on household pets, and the evidence shows where the risk concentrates. 

The Australian Veterinary Association links climate change to more droughts, heatwaves, bushfires and floods. 

It says heat stress commonly affects pets.^[7]

Heat Reaches the Backyard

Heatstroke, a life-threatening rise in body temperature, can cause rapid multi-organ failure and death in pets. 

RSPCA Australia calls it an emergency that demands immediate veterinary attention. 

The organisation says the risk is increasing as heatwaves grow more frequent and prolonged.^[8]

A study in the Australian Veterinary Journal analysed two decades of New South Wales veterinary data. 

Dog mortality risk rose 0.6% for each degree of daily maximum temperature above 25°C. 

Extreme heat days above 32°C, the 95th percentile of regional daily maximum temperatures, carried a 9.5% higher risk.^[1]

Public holidays and Sundays carried higher mortality risk even after the analysis controlled for temperature. 

Sundays showed nearly double the risk of other days of the week. The authors say veterinary public health policy and key messaging about heat deaths in dogs should use these findings.^[1]

Individual risk varies with age, body condition, health and breed. RSPCA Australia identifies obese dogs and brachycephalic (flat-faced) breeds such as pugs and bulldogs as high-risk. 

Both groups have a reduced capacity to regulate body temperature.^[2]

Where the Risk Concentrates

Humidity amplifies heat. RSPCA Australia lists warm, humid weather, poor airflow and scarce shade among the main heatstroke risk factors. Heatstroke can still develop in cooler weather when several of those factors combine.^[8]

Parts of northern Australia have already recorded such conditions. RSPCA Australia’s 2020 research report documents record humidity, rainfall and flood risk in some northern regions during 2019. It draws that finding from the Bureau of Meteorology’s annual climate statement.^[2]

Agriculture Victoria says heat load builds when overnight temperatures stay above 25°C across consecutive hot days. Its guidance covers pets and livestock. It urges planning for days above 36°C in dry heat, or lower when humid.^[3]

Cities add a structural hazard. The urban heat island effect, where built-up areas run hotter than surrounding land, raises heat illness risk for city animals. RSPCA Australia flags that risk in its research report.^[2]

Parasites Shift Their Range

Vectors are organisms such as mosquitoes and ticks that carry disease. The Australian Veterinary Association says warmer temperatures and rain events that aid vector breeding have increased several diseases. Some diseases have also shifted geographically.^[7]

Researchers writing in The Conversation expect heat and floods to aid the spread of parasites and illness. They name tick-borne disease, flea infestations and heartworm as likely consequences for pets. The authors conclude that pets will need human help to cope.^[4]

RSPCA Australia notes suggestions that shifting humidity and temperature in Queensland sustain heavy flea burdens. It expects higher risk from heartworm, a mosquito-borne parasite of dogs. It also expects more irritation and allergies from arthropods such as fleas, ticks and mites.^[2]

Evidence remains thin. In 2020, RSPCA Australia found a general lack of peer-reviewed literature that systematically assesses climate-related welfare risks to animals. It says further research must establish the range and extent of those risks.^[2]

Evacuation Without a Plan

Extreme weather can displace pets. RSPCA Australia warned in 2020 that owners may delay evacuating when pets lack accommodation. It tied that concern to South Australia and Western Australia, where evacuation centres excluded pets other than assistance animals.^[2]

In February 2026, RSPCA WA and the Department of Fire and Emergency Services urged households to plan for pets. The call followed a string of Western Australian bushfires. RSPCA WA’s chief operating officer said community evacuation centres generally exclude animals other than recognised assistance animals.^[5]

Australian emergency arrangements assign formal roles to response agencies, but individual pet owners ultimately retain responsibility for their animals. A survey of Townsville residents in the Australian Journal of Emergency Management found most pet owners uncertain or underprepared. 

The authors frame this as shared responsibility and urge households to plan ahead for their pets.^[9]

Disaster specialist James Sawyer wrote in 2024 that animal evacuation planning stays informal without legislation. Resources then rely on volunteers, and authority is largely absent. He described the planning and resourcing gap for evacuating people with animals as huge.^[10]

The Summer Ahead and Owner Duties

El Niño is a warming of the tropical Pacific Ocean that shifts weather patterns across Australia. The Bureau of Meteorology says all models forecast warmth peaking around November or December and persisting into autumn 2027. 

Most models show monthly peaks above +3.0°C on the Relative Niño3.4 index, higher than any since 1950.^[6]

Agriculture Victoria says responsibility for preparing animals for heat events rests with owners and carers. Victorian guidance limits unattended time in a vehicle to 10 minutes on days above 28°C. At 28°C or above, dogs riding on metal ute trays need an insulating layer beneath them.^[3]

RSPCA Australia advises giving pets free access to water and cool areas. Cats may need confinement indoors when outdoor conditions turn too hot. Rabbits, guinea pigs and other caged animals need a cool, shaded, ventilated spot indoors, such as a laundry.^[8]

Signs of heatstroke vary by species but may include lethargy, fast breathing, shaking and collapse. RSPCA Australia directs owners who suspect heatstroke to seek veterinary attention immediately. Very young animals regulate body temperature poorly, and very old animals often carry conditions that limit cooling.^[8]

Conclusion

Veterinary data and animal welfare bodies show that climate change already endangers Australian pets. Heat, humidity, hot pavements and spreading parasites each raise the risk, and research gaps still limit the picture.

Responsibility rests largely with owners, and evacuation rules in Western Australia leave households to arrange their own shelter. One disaster specialist argues that legislation would close the planning gap and give agencies a clear mandate.

The El Niño summer will test those arrangements. Accountability depends on whether lawmakers, agencies and veterinarians share the duty that owners already carry. 

Owners can act now by planning for heat, smoke, flood and evacuation before summer peaks.

Australia Faces a $181 Billion Bushfire Bill as Fire Seasons Lengthen and Preparation Lags - Lethal Heating Editor BDA

Climate-fuelled bushfires could cost Australia $181.7 billion
over 30 years according to new modelling

Key Points

Bushfires could cost Australia $181.7 billion over 30 years, an average of $6 billion a year.[1] Health and wellbeing absorb 32 per cent of the annual bill, ahead of lost business output at 25 per cent.[2] Fire seasons are 21 per cent longer than in 1979, and 5.6 million households face bushfire risk.[3] Black Summer killed 33 people, and smoke caused another 429 premature deaths.[4] Cutting bushfire damage by a fifth could prevent $39.4 billion in losses and protect more than 5,600 jobs a year.[1] Climate hazards could cause up to $744 billion in property damage by 2100, and adaptation could avert up to $240 billion.[5]

Cobargo, on the New South Wales south coast, is still rebuilding after the Black Summer fires. 

Former ACT Emergency Services Authority commissioner Peter Dunn says that toll extends well beyond money. 

His message to governments is direct: start preparing now.^[1]

Emergency Leaders for Climate Action, a group of former senior fire and emergency service leaders, commissioned the analysis. 

Titled Prepare or Pay, the report uses ConnellGriffin modelling to project $181.7 billion in losses over 30 years. 

Authorities warn of an unusually warm summer and an early bushfire season.^[1]

Report and Methodology

Emergency Leaders for Climate Action commissioned the modelling from ConnellGriffin. 

Economic advisory lead Jessica Yu says the figures count idle farms, closed businesses, lost jobs and harm to health. 

The report appendix sets out the full methodology.^[2]

The report treats climate-fuelled bushfires as fires that pollution from coal, oil and gas makes more extreme. 

Its modelling assumes the current high-emissions scenario continues without major change. 

An emissions scenario is a projected pathway for future greenhouse gas pollution.^[2]

Co-author Janice Lee calls the estimates conservative. The modelling leaves out losses to wildlife, ecosystems and cultural heritage. She says fires that struck once in a generation now occur more frequently.^[1]

Resourcing gaps in fire services compound the risk as seasons lengthen. Firefighting volunteer numbers fell by 10,336 between 2019 and 2023/2024, while paid positions grew by only 433. Greg Mullins, who founded the group, says firefighters need long-term government backing.^[2]

Economic Costs

Health and wellbeing account for 32 per cent of the $6 billion annual bill. Lost business output follows at 25 per cent, then damaged schools and workplaces at 20 per cent. Damaged homes represent 17 per cent and lost work 6 per cent.^[2]

A disaster on the scale of Black Summer would cost $27.7 billion, the modelling shows. Major fires would cost $16.1 billion every three to four years. Harm to health ranks first among the losses, followed by lost business output, damaged buildings and destroyed homes.^[1]

Insurance data captures a fraction of that bill. The Insurance Council attributes about $2 billion of the $2.58 billion in bushfire claims since 2019 to Black Summer. Research puts the tourism loss alone near $3 billion.^[3]

Longer-run evidence points the same way. The Royal Commission into National Natural Disaster Arrangements cited projections of rising costs. Annual disaster costs would climb from $18.2 billion to $39 billion by 2050, even without climate change.^[6]

Health and Communities

Black Summer killed 33 people, and smoke caused another 429 premature deaths. Peak health bodies warned that the mental health effects were likely to last decades. Such harm explains why health and wellbeing form the largest share of projected losses.^[4]

Smoke particles aggravate existing illness, especially in older people and anyone with heart or lung disease. For people with heart disease, exposure raises the risk of angina (chest pain), heart attack and stroke. Repeated heavy smoke seasons may also affect lung development in some children.^[7]

Half of Australian households, about 5.6 million, face some bushfire risk. More than one million Australians lived within one kilometre of an active fire front between 2003 and 2020. El Niño often brings hotter and drier conditions to southern and eastern parts of Australia.^[3]

Intangible costs, such as trauma and lost wellbeing, carry no market price. A study of Black Saturday used life satisfaction data to show bushfires significantly reduce reported wellbeing. Its authors identified a gap between current spending on bushfire response and mitigation and the level that would maximise welfare.^[8]

Climate and Fire Risk

Fire seasons are 21 per cent longer than in 1979. That shrinks the windows for hazard reduction burns, which are planned fires that cut flammable fuel. It also limits how much states and territories can help each other.^[2]

The report links pollution from coal, oil and gas to worsening extreme fire weather. Former Fire and Rescue NSW commissioner Greg Mullins says fire-generated storms are six times more common than 20 years ago. He urges political leaders to stop approving new coal and gas projects.^[2]

The report describes a new era of fire, with major events striking every three to four years. A hotter baseline now combines with El Niño, an unusual warming of the central Pacific that is shaping as record-breaking. Mullins warns that the 2027/2028 summer could prove hotter still.^[2]

Black Summer shows how far one catastrophic season spreads. WWF-Australia commissioned scientists who estimated that the fires killed or displaced nearly three billion animals. WWF-Australia chief executive Dermot O’Gorman called the findings shocking.^[9]

Prevention and Adaptation

Cutting bushfire damage by a fifth could prevent $39.4 billion in losses, according to Janice Lee. That reduction would protect $17 billion in tax revenue. It would also sustain more than 5,600 jobs each year.^[1]

Protecting homes and infrastructure could avoid about $600 million in bushfire losses each year. Priorities include upgrading homes to bushfire standards so that they withstand fire. Communities also need electricity and communications after a fire.^[3]

The report urges the Australian Government to finalise and fund a detailed National Adaptation Plan. It recommends retrofitting at-risk homes to national bushfire standards at an estimated $39,466 per home. It also seeks 48 hours of backup power for mobile towers in high-risk areas and a domestic aerial firefighting capability.^[2]

The Productivity Commission’s inquiry report projects that climate hazards could cause up to $744 billion in property damage by 2100. Adapting existing properties and improving land planning could cut that damage by up to $240 billion. Analysis by XDI modelled the reduction from greater housing resilience measures.^[5]

The $181.7 billion projection exposes a gap between what bushfires cost and what Australia invests to prevent them. Health, business and housing losses accumulate each year, long before any single catastrophe arrives.

Accountability rests with governments that set emissions policy, approve fossil fuel projects and fund fire services. Shrinking volunteer ranks and unfinished adaptation planning show where preparation lags. Responsibility for closing that gap sits with the Commonwealth and every state and territory.

The modelling gives prevention a measurable value. Cutting damage by a fifth could protect $39.4 billion and thousands of jobs. That gives governments a financial case to act before the next major fire.

Australia's Supercharged Fire Seasons Now Cost $6 Billion a Year, Report Finds - Lethal Heating Editor BDA

Australia confronts its costliest fire era
as a record El Niño gathers strength offshore

Key Points

Bushfires now cost Australia about $6 billion a year, projected to exceed $180 billion over 30 years.[1] Health and wellbeing absorbs 32 per cent of that bill, ahead of lost trade and damaged property.[1] Recorded extreme fire-generated storms rose six-fold, from 20 in 1983–2003 to 121 in 2004–2024.[1] Black Summer stripped $2.8 billion from tourism supply chains and 7,300 jobs nationwide.[3] The Snowy Valleys lost 12,400 hectares of softwood plantations, delaying full production until about 2040.[2] Better protection of homes and infrastructure could save $600 million and 5,600 jobs annually.[1]

Six years after fire tore through the Snowy Valleys, pine seedlings stand in rows where mature plantations once grew. 

A former timber worker drives the same road he drove before Black Summer, past paddocks that still carry the faint scars of that season. 

The hills have greened, yet the mill that fed his family remains quiet, waiting on trees that need two more decades to mature.

His wait measures something Australia struggles to count. 

The country's fire seasons have lengthened by 21 per cent since 1979, extending the danger window and the damage it delivers.^[2]

New modelling commissioned by Emergency Leaders for Climate Action puts the annual cost of that longer season at $6 billion.^[1]

The Cost of Longer Fire Seasons

Emergency Leaders for Climate Action is a coalition of former fire and emergency chiefs pressing for faster emissions cuts. Its Prepare or Pay report models the average annual bushfire burden on the Australian economy across the next 30 years.^[1]

That burden reaches $6 billion each year, and cumulative losses exceed $180 billion without stronger action.^[1]

Health and wellbeing absorbs 32 per cent of the total, through smoke illness and psychological trauma. Lost trade accounts for 25 per cent, damaged businesses and public buildings 20 per cent, lost homes 17 per cent and lost work 6 per cent.^[1]

Fire behaviour has shifted alongside the ledger. Recorded extreme fire-generated storms rose from 20 between 1983 and 2003 to 121 between 2004 and 2024, a six-fold increase.^[1]

What Black Summer Cost

Black Summer delivered the clearest accounting yet of what a supercharged season extracts from a nation. University of Sydney researchers traced the 2019–20 fires through tourism supply chains and found $2.8 billion in lost output, with 7,300 jobs disappearing nationwide.^[3]

The Insurance Council of Australia recorded $2.32 billion in insured losses across the four affected states for that season.[4]

New South Wales alone lost 26 lives, 2,448 homes and 5.5 million hectares, its worst season on record.[4]

Suncorp analysis submitted to Treasury estimated total economic costs near $4.4 billion from the fires.[5] 

 

Snowy Valleys: A Case Study in Slow Recovery

The Snowy Valleys Council area lost roughly a third of its landscape to fire in 2019–20. Council records put direct recovery spending at about $5.7 million.^[2]

Fire killed an estimated 12,400 cattle and 9,600 sheep across the local government area. It burned through 68,000 hectares of softwood and native forest.^[2]

Softwood production will stay well below capacity until around 2040. Radiata pine takes 25 to 30 years to reach harvest maturity.^[2]

Housing recovery has moved at a similar pace. More than six years on, hundreds of homes remain unbuilt across the region.^[6]

El Niño and the Season Ahead

The Bureau of Meteorology declared El Niño in June 2026 and forecasts persistence into the 2026–27 summer. Models indicate it may rank as the strongest event since reliable records began in 1950.^[7]

Drier-than-average conditions have settled across north-eastern New South Wales, southern Queensland and southern Victoria since January.^[8]

Rainfall deficits dry out soils, grasslands and forest fuels, priming landscapes for ignition.^[8]

Bureau climatologists caution that event strength rarely predicts impact. ENSO remains one influence among several, including the Indian Ocean Dipole and local conditions.^[9]

Preparation, Resilience and What Could Be Saved

Approximately 1.5 million Australian households face some bushfire risk. More than half a million sat within one kilometre of an active fire front between 2003 and 2020.^[2]

ELCA modelling suggests that making fires one-fifth less damaging would protect over 5,600 jobs and $600 million in losses each year.^[1]

The federal Disaster Ready Fund has committed $600 million across more than 450 projects in its first three rounds. That $1 billion program runs over five years.^[10]

Retrofitting a home to the national bushfire standard costs about $39,466 on average, and lifecycle benefits exceed those outlays.^[1]

The evidence assembled here traces a consistent pattern. Longer seasons, fiercer storms and heavier bills now define the Australian fire year, and the public purse carries much of that weight.

Governance has lagged the science. Prevention spending remains modest beside the damage it might avert, while insurance retreat leaves exposed households bearing risks alone.

Accountability belongs to governments at every level. Their choices on emissions, land management and household resilience will decide how Australia's next fire season is counted.
