Demand action from governments to mitigate the costs from escalating climate-driven "natural" disasters

CLIMATE BRIEFING
Each summer in Australia brings more frequent, more severe, and more expensive weather events to Australia - heatwaves, bushfires, flooding and cyclones intensified by climate change. These events are an increasing risk to lives, communities, the environment and the economy. Australian governments must act now to reduce emissions, strengthen resilience, and protect the most vulnerable Australians from the escalating impacts of climate-driven disasters.
This climate briefing is part of our series of simple, easy-to-follow guides and email templates on big climate topics for Australia. They’re designed to help you get across the issues, feel more confident speaking up, and make it easy to send a message to your MP about the things you care about.

Background and context:

In the first three months of 2026, we’ve already experienced a record-breaking heatwave, the wettest summer in a decade, and a bushfire with speed and scale unlike anything ever seen - as well as widespread flooding and a handful of cyclones. Australians are no stranger to extreme weather events, but even by our standards, this summer was brutal - and it is a sign of what is to come under a climate change future. While these extreme events do occur naturally in the weather system, the devastating intensity, frequency and scale is the inevitable consequence of climate change, and the links between climate change and extreme weather events is made clear by the IPCC: human-induced greenhouse gas emissions have increased the frequency and intensity of many extremes - including heatwaves, heavy rainfall, droughts, tropical cyclones and fire conditions - and even small rises in global temperature significantly amplify these risks across regions worldwide. Australia being flung from one extreme event to another has been called climate whiplash, a phenomenon that causes more harm than individual events alone due to cascading impacts across agriculture, infrastructure, biodiversity and human health.

On average, the Australian government spends $1.6 billion each year on disaster recovery as we experience some of the highest per capita losses in the world. Around $4.5 billion in insurance claims related to extreme weather are made annually, nearly three times higher than the 1990s. Australia’s poorer communities are often disproportionately burdened - for example the majority of homes that are unable to have flood insurance coverage are in regions with average incomes below the national median, meaning the most vulnerable Australians are unlikely to have a safety net if they are impacted. 

The non-economic impacts are also vast. People are displaced, the cost of groceries increases, and farmers struggle to provide food and other agricultural products. Our health system faces additional pressure during and after extreme events due to increased numbers of injuries and deaths (including more than 1,000 hospitalisations per year due to extreme weather-related injuries) and the mental health burden faced by people that experience, or worry they might experience, extreme weather. Our wildlife and environment suffers extreme losses, including mass mortality of affected species and habitat disruption when ecosystems are damaged or destroyed.Record global levels of fossil fuel pollution are influencing our extreme weather events more than natural drivers like the ENSO cycle. Already, attribution analysis has been published that shows the heatwave experienced in January 2026 was made five times more likely by anthropogenic climate change - particularly concerning as heatwaves are our deadliest natural hazard, causing more fatalities in the last 125 years than bushfires, cyclones, earthquakes and floods combined. It’s a sign of what is to come: the 2025 National Climate Risk Assessment warns the number of days of heatwave we experience each year, and the number of heat-related deaths, could quadruple if greenhouse gas emissions are not reduced. The same assessment also estimates that millions of people will be at risk due to worsening bushfires, rainfall, riverine and coastal flooding and tropical cyclones.

The financial toll will also worsen, as many properties and assets are falling outside of insurance schemes as they become increasingly unaffordable in the wake of extreme weather events, and one in every 25 properties will be effectively uninsurable by 2030 due to the risk of extreme weather. Economic modelling estimates that by 2060, the cost of natural disasters could increase to $73 billion per year - even under a low emissions scenario - due to worsening coastal inundation, bushfires, floods and tropical cyclones driven by climate change, and could trigger cascading shocks to Australia’s communities, economy, national security, infrastructure, healthcare, primary industries and natural environment. 

Today’s choices shape the world we will live in. The Australian government must act decisively to reduce greenhouse gas emissions and exceed our 2035 emissions reduction target, while strengthening climate adaptation measures to ensure Australians are prepared for the growing impacts of extreme weather. This could mean investing in resilient infrastructure and services, reforming the insurance schemes, and improving the health of our ecosystems to provide natural protection.

Why is this important?

  • Heatwaves, bushfires, floods, and cyclones are becoming deadlier and more frequent, disproportionately affecting vulnerable Australians
  • Extreme weather is driving up insurance costs, disaster recovery spending, and could cost Australia $73 billion annually by 2060
  • Without immediate government intervention on emissions reduction and climate adaptation, the severity and frequency of disasters will continue to escalate and Australians will remain unprepared

Desired outcomes:

  • Exceed Australia’s 2035 emissions reduction target, particularly by halting new approvals for fossil fuel projects
  • Invest in adaptation and resilience initiatives that help at-risk communities prepare for, adapt to, and recover from bushfires, floods, cyclones, and other disasters

Who to contact:

  • Your local Federal MPs (check on this website if you’re unsure who that is)
  • Key Federal Ministers (addresses in link) including: Prime Minister Anthony Albanese; Environment Minister Murray Watt; Climate and Energy Minister Chris Bowen
  • Federal Senate Crossbenchers (addresses in link) including the Greens, Independents David Pocock (ACT) and Fatima Payman (WA), and Jacquie Lambi (JLN), who hold the balance of power in the Senate

Other resources

  • The Climate Council has a Climate Risk Map and a Climate Heat Map available. You can enter your postcode into these tools to get a clearer idea of what natural disasters pose the biggest risk in your area. We encourage you to use this information to personalise MP emails, calls or visits to those disasters that post the biggest risk to your suburb or electorate.
  • Climate Council research also estimates the overwhelming majority of Australians - 84% - have been directly affected by at least one climate-fuelled disaster since 2019. Think back on the last few years and see if you can localise your MP contact to different events you, your family, and your neighbours might have experienced.

  • Guidelines and tips for writing emails

Actions you can take:

1. Email your MP or relevant Ministers

If you need some help getting started with your email, here is an example. 

Please don’t copy it exactly - personalise it and tailor it to the MP you are writing to. 

In addition, when writing to a Minister or Shadow Minister, start by saying that you’re writing to them in their role as Minister for xxxx, otherwise they will probably just forward your email to your local MP.

[MP name]

[Member for …. or  Minister for ….]

Dear …

[Include a personal statement - who you are and why you care]

In the first three months of 2026 alone, we have already experienced record-breaking heatwaves, widespread flooding, devastating bushfires, and multiple cyclones. These events are becoming more frequent, intense, and costly due to human-induced climate change, placing lives, communities, and the economy at risk. Vulnerable Australians, including those in low-income regions, are disproportionately affected, while insurance costs and recovery expenses continue to rise. Without immediate action to reduce emissions and strengthen resilience, the scale and severity of disasters will only worsen.

[add a personal reflection on your experience with extreme weather events, or those that might occur in your electorate, using the Climate Council tools linked above]

How will you support stronger emissions reductions to limit global warming and protect Australians from escalating climate disasters? 

What plans do you have to invest in resilience measures to help our community prepare for, adapt to, and recover from bushfires, floods, cyclones, and other climate-driven events?

Will you support a tax on gas exports to help fund resilience and adaptation measures? 

I look forward to your response.

Sincerely

2. Call your MP

Here is a suggested script to get you started:

Hi, my name is ….. and I’m a voter in [your electorate].

I’d like to speak to …..[name of MP]

(Staffer will probably say: I’m sorry they’re not available, can I take a message?)

Yes, thank you! Would you please tell them:

  • I’m really worried about the increasing frequency and severity of extreme weather across Australia - I’ve seen the news about bushfires, floods, heatwaves, cyclones and I am concerned climate change is putting lives, livelihoods, and our economy at risk.
  • I’m worried because my insurance premium has increased this year, and I think climate change is going to force it up further, making it unaffordable - which will leave my home and family at risk.

And ask them to:

  • Commit to stronger emissions reductions to limit global warming and reduce the risk of extreme weather
  • Invest in resilience measures that help [my electorate] prepare for, adapt to, and recover from bushfires, floods, cyclones, and other climate-driven disasters
  • Support a tax on gas exports

Thank you!

3. Visit your MP

HOW GLOBAL WARMING AFFECTS WATER CYCLES AND FRESH WATER

Disrupting the water cycle

Global warming is changing how water moves through Australia’s environment, with serious consequences for fresh water availability. Rising temperatures increase evaporation from soil, rivers, and reservoirs, which in turn creates more precipitation and more frequent, more intense storms. These changing rainfall patterns also change the frequency and severity of floods and droughts, and can lead to depletion of groundwater as irrigated agriculture, farms and cities rely heavily on ever-decreasing freshwater supplies. While northern Australia is expected to receive more rainfall in a climate-impacted future, the heavily-populated southern and eastern areas of the mainland will receive less
