Australia’s Home Insurance Crisis: Rising Premiums and the Impact of Natural Disasters

Australian homeowners are facing a rapidly escalating home insurance crisis, with premiums soaring across the country, particularly in regions prone to natural disasters. What was once an affordable necessity is becoming increasingly out of reach for many, prompting concerns about a growing protection gap and the future of homeownership in vulnerable areas.

The Rising Cost of Coverage

The average cost of home insurance in Australia has increased significantly in recent years. According to analytics firm Finity, the average home insurance cost rose by 51% over the past five years, from $1,940 in 2020 to $2,938 by October 2025. Some homeowners are experiencing even more dramatic increases. Paul and Denise Cameron, retirees in Dargen, New South Wales, saw their annual premium nearly double from $2,603 in 2019 to $5,071 today, even with a 30% discount for long-term loyalty and multiple policies with NRMA.

Regional Disparities in Insurance Costs

Insurance costs vary considerably depending on location. As of October 2025, Darwin residents pay the highest average premiums at $4,015 per year, followed by Sydney ($3,964) and Brisbane ($3,872). Other cities and their average costs include: Canberra ($2,622), Melbourne ($2,520), Hobart ($2,268), Perth ($2,203), and Adelaide ($2,042). Within these cities, certain areas bear a disproportionate burden. Residents in Brisbane’s west face the highest premiums, averaging $8,396 annually, while those in Darwin City and Sydney’s outer west and Blue Mountains region average $5,410 and $5,350, respectively.

Drivers Behind the Price Hikes

Several factors are contributing to the surge in home insurance premiums. According to Stephen Lau, a principal at Finity, the increasing frequency and severity of disasters linked to climate change, coupled with rising building costs, are the primary drivers. Insurers are grappling with a substantial increase in claims, with around 300,000 claims filed for the 2022 floods alone, creating significant pressure on repair and building material demand. Rising construction costs and persistent inflation are as well contributing to the problem.

Suncorp, a major insurance provider, acknowledged that extreme weather events, rising construction costs, and inflation are impacting insurance affordability for all Australians. The company employs data modeling and risk assessment to determine premiums for individual properties.

The Impact of Natural Disasters

Australia has experienced a series of devastating natural disasters in recent years, including the 2019-2020 “Black Summer” bushfires and numerous floods. These events have resulted in billions of dollars in insurance claims. Since 2020, extreme weather events have cost insurers a total of $25.3 billion, averaging $4.8 billion per year – a 38% increase compared to the previous five years. In the first half of 2025 alone, over $1.8 billion in claims were filed due to extreme weather, with costs expected to be passed on to consumers.

Mitigating Risk and Reducing Premiums

Homeowners can take steps to reduce their risk and potentially lower their premiums. The Resilience Building Council (RBC) offers a free service to help homeowners identify and address vulnerabilities. The RBC assesses properties and provides a risk rating from one to five stars, recommending specific actions to improve resilience. These actions may include strengthening structures against floods, upgrading materials to be more flood-resistant, protecting windows and roofs from storms, and clearing flammable materials around the home to mitigate bushfire risk.

The Camerons, for example, reduced their annual premium by approximately $500 by implementing fire risk mitigation measures and presenting a certificate from the RBC to their insurance provider.

The Affordability Crisis and the Future of Insurance

Despite mitigation efforts, affordability remains a significant concern. Actuaries Institute data indicates that 15% of Australian households already cannot afford home insurance, and this number is expected to grow. Kate Cotter, CEO and founder of the RBC, warns that unless proactive measures are taken to adapt buildings and reduce risk at the community level, the insurance market could face significant challenges.

The Insurance Council of Australia is collaborating with the federal government to explore solutions, including public-private partnerships and improved land use planning. Businesses are also feeling the strain, with BizCover data showing that business claims for severe weather events have almost doubled in the last three years. Power outages, fires, and storm damage are the top threats to business operations nationwide.
