Worsening extreme weather means increased costs of maintenance, repair and replacement to properties – homes, workplaces and commercial buildings. As the risk of being affected by extreme weather events increases, insurers will raise premiums to cover the increased cost of claims and reinsurance.

Insurance will become increasingly unaffordable or unavailable in large parts of Australia due to worsening extreme weather.

This report outlines the top 20 most at-risk federal electorates to climate change-related extreme weather events, providing a brief profile of the top 10. The report also outlines the most at risk electorates for each state and territory.

Key findings:

• Climate change is creating an insurability crisis in Australia due to worsening extreme weather and sky-rocketing insurance premiums.
• Climate change affects all Australians, but some federal electorates face far greater risks than others.
• Riverine floods are the most costly disaster in Australia.
• Decisions and actions over this next term of government will influence the future impacts of climate change for generations to come.
