A Nation Confronts a Warming Future

Report

The National Climate Risk Assessment 2025 is the first government-wide assessment of climate threats to Australia’s society, economy, and environment. It was commissioned by the Commonwealth Government to provide a structured understanding of the risks climate change poses across critical systems. The assessment was coordinated by the Department of Climate Change, Energy, the Environment and Water (DCCEEW), drawing on data and expertise from agencies including CSIRO, the Bureau of Meteorology, Infrastructure Australia, and health authorities. Its purpose is to inform national decision-making by identifying priority risks and vulnerabilities that require urgent attention. The report also integrates consultation with states, territories, industry, and Indigenous communities to ensure diverse perspectives are represented. Ultimately, it is intended as a foundation for future national adaptation planning, guiding policy, investment, and community resilience.

Key Points

Heat, drought, and fires disrupt daily life[1] Insurance and housing pressures are rising[6] Indigenous communities face severe cultural risks[13] Economic costs from climate damage are escalating[5] Policy decisions in the next five years are critical[23]

Social Impacts

The Climate Risk Assessment warns that vulnerable populations, including the elderly and outdoor workers, face disproportionate health risks^[1].

The report notes that without intervention, social divisions could deepen^[2].

This adds pressure to healthcare systems that are already stretched^[3].

Economic Consequences

Farmers in the Murray-Darling Basin are already reporting crop losses and water scarcity^[4].

A single disruption in coal or gas exports could trigger billions in losses^[5].

This creates a feedback loop of declining property values and social stress^[6].

Ecological Pressures

Coral loss threatens biodiversity and undermines tourism revenue^[7].

Species with limited mobility, including koalas, are particularly vulnerable^[8].

This has already contributed to mass fish kills in inland river systems^[9].

Political and Policy Challenges

Critics argue that approving new gas and coal projects undermines Australia’s credibility in global negotiations^[10].

Others remain tied to resource exports, creating a fragmented national strategy^[11].

Failure to respond effectively risks fuelling political disillusionment^[12].

Cultural and Indigenous Dimensions

Traditional knowledge offers adaptive insights, but communities often lack structural support^[13].

Many Indigenous leaders call for co-management of climate adaptation plans^[14].

Exhibitions, literature, and performances increasingly frame climate change as a shared cultural struggle^[15].

Community Responses

Communities in fire-prone regions are creating volunteer networks to build resilience^[16].

Yet critics warn that voluntary action is insufficient without systemic regulation^[17].

Younger generations are driving advocacy, demanding urgent reforms across politics and business^[18].

Global Context

The report warns that continued reliance on carbon exports risks long-term economic isolation^[19].

This vulnerability underscores the need for resilience planning^[20].

Australia’s response will shape regional alliances and influence global negotiations^[21].

Outlook

Climate impacts will test not only physical infrastructure but also the resilience of democratic institutions and cultural identity^[22].

The choices made in the next five years will be decisive^[23].

The report argues that collective action across all sectors of society can still bend the trajectory^[24].
