Rising home insurance premiums driven by climate disasters have left Australians facing a widening protection gap, with property owners in high-risk flood zones seeing annual quotes skyrocket to as high as $50,000, according to industry analysis and affected residents.
Climate Disasters Drive Australian Home Insurance Premiums to Record Highs
Escalating climate disasters across Australia are triggering a severe insurance affordability crisis, forcing growing numbers of property owners to drop flood coverage or abandon policies altogether. According to data from actuarial firm Finity, regions with the highest insurance premiums directly correlate with extreme flood risk, particularly along the country’s east coast.
Megan Vicary, a 52-year-old resident of Yarramundi in the Hawkesbury region, watched her annual home insurance jump from $6,000 to $35,000 following four floods in 2022, before reaching quotes as high as $50,000. She told reporters that many insurers no longer offer flood coverage for her postcode, leaving her policy entirely devoid of water damage protection. “If we have a major flood, it is going to be a crisis because none of us can afford it,” Vicary said.
Nationally, about 1.4 million properties face some level of flood risk, including nearly 300,000 facing severe-to-extreme annual threats primarily across New South Wales, Queensland, and Victoria, according to the Insurance Council of Australia.
East Coast Flood Zones Bear the Heaviest Financial Burden
Geographic analysis reveals stark regional disparities in insurance cost spikes. On the east coast, the Richmond-Tweed region in the New South Wales Northern Rivers recorded an 81 per cent premium increase since January 2021, pushing the average quote for a new policy to $8,836 a year, according to Finity’s findings. This statistical area encompasses Lismore, Tweed Heads, Murwillumbah, Byron Bay, and Ballina.
In Victoria, the Shepparton region experienced a 77 per cent increase, with average quotes reaching $4,871 annually. Queensland’s west of Brisbane saw average home insurance climb 74 per cent to $6,173. All three regions share a history of devastating floods over the past decade, peaking during the 2022 disaster season. New South Wales premiums carry an additional weight due to an emergency services levy of 15 to 18 per cent, prompting the state government to consider financial reforms.
By contrast, Cairns regional premiums dropped over a five-year period to an average of $3,985 a year. Finity principal Stephen Lau attributed this localized decline to the federal government’s establishment of a northern Australia cyclone reinsurance pool, which is monitored by the Australian Competition and Consumer Commission.
The Hidden Costs of Self-Insuring and Rebuilding Better
As insurance becomes financially untenable, many homeowners choose to self-insure or rely on personal savings for disaster recovery. Vicary reported spending $65,000 of her own savings to replace fences, clear out low-lying sheds, and dispose of river-dumped debris, including a washing machine and half a speedboat.
For those who can afford to rebuild, upgrading structural resilience does not guarantee lower insurance bills. Sarah Thomson, 53, and Bec Nicoll, 56, spent $500,000 of their own money alongside an insurance payout to reconstruct their Kialla home near Shepparton 1.25 metres higher than their previous dwelling, incorporating Passivhaus principles and bushfire codes. Despite building well above mandated flood levels, their new annual insurance premium reached $6,100—with some quotes hitting $18,000—because sales agents noted that resilience features are not factored into standard pricing models.
Insurance Council chief executive Andrew Hall warned that vulnerable communities face a compounding trap. “When the worst happens to them… they just go backwards, and [that] creates this intergenerational cycle of poverty because they’re caught in a trap that they can’t get out of,” Hall said.
Proposed Reforms and Community-Level Defenses
To address the disconnect between home improvements and premium pricing, the Housing Resilience Action Plan proposes a national rating system. Developed collaboratively by Finity, the Resilient Building Council, Monash University, and consumer advocacy groups, the framework would assign every Australian home a star rating based on natural disaster risk and structural resilience.
Finity principal Sharanjit Paddam explained that the system aims to establish a common language for consumers, insurers, and banks. Under the proposal, renewal notices would explicitly show how a home’s star rating impacts its insurance cost, empowering owners to make informed investment decisions.
However, industry leaders emphasize that household upgrades alone cannot solve macro-level risks. The Insurance Council has urged governments to establish a 10-year, $30 billion flood defence fund to construct hard infrastructure like levees in 24 priority eastern state catchments.

Frequently Asked Questions
Why are home insurance premiums increasing so rapidly in Australia?
Premiums are surging primarily due to mounting climate disasters, particularly frequent and severe flooding events along the east coast, which have driven up underwriting risks for insurers.

What regions in Australia currently have the highest insurance quotes?
According to Finity data, the Richmond-Tweed region in New South Wales holds the highest average east coast premiums at $8,836 annually, followed by west of Brisbane in Queensland at $6,173 and Shepparton in Victoria at $4,871.
Do home resilience upgrades lower insurance premiums?
Currently, many insurance sales agents do not factor property-level resilience improvements—such as elevated foundations or flood-resistant materials—into policy pricing, though proposed rating systems aim to change this in the future.
What is the proposed Housing Resilience Action Plan?
It is a collaborative initiative designed to create a standardized star-rating system for Australian homes, allowing insurers, banks, and consumers to link property disaster resilience directly to insurance pricing.
