Australian Homes Facing Rising Climate Risk: The Urgent Need for Resilience and Insurance Adaptation

Australia’s Climate Risk: Why Half a Million Homes May Soon Be Uninsurable


The Climate Change Authority warns nearly 600,000 Australian homes could become uninsurable within five years. Discover the urgent need for action and how Business Insurance Consulting can help you prepare.

Australia’s Growing Climate Crisis: Is Your Home at Risk of Becoming Uninsurable?

Australia is renowned for its beautiful landscapes and diverse climate, but this very diversity increasingly poses severe risks. According to a recent report by the Climate Change Authority, approximately 589,000 Australian homes could soon become effectively uninsurable due to heightened flood risks, extreme weather events, and the impacts of climate change. With potential annual costs of up to $8.7 billion by 2050 if no preventative measures are taken, Australians face a critical choice: adapt now or risk devastating financial impacts later.

At Business Insurance Consulting, we believe homeowners must understand these emerging risks and take proactive steps to protect their assets and livelihoods.

The Growing Threat: Why Australian Homes are Becoming Uninsurable

The Climate Change Authority’s latest findings highlight a stark reality: more Australian homes than ever are under threat from climate-driven disasters. The devastating flooding along the NSW Mid North Coast in May 2025 is just one recent example. Unfortunately, such incidents are predicted to become increasingly common as extreme weather patterns intensify.

The authority’s Chair, Matt Kean, underscored the urgency, stating clearly that the recent floods “won’t be the last”. This reflects a worrying trend where properties currently considered safe may become high-risk in the near future, pushing them closer to the dreaded label of being “uninsurable”.

Homes categorised as “uninsurable” often face prohibitively high insurance premiums or are simply unable to secure coverage at all, placing severe financial burdens on owners who must bear the full cost of recovery after disasters.

Why Immediate Action is Essential

The Climate Change Authority’s report makes it clear: doing nothing is not an option. Without coordinated national efforts to reduce climate risks, the annual economic impact of extreme weather events could skyrocket to nearly $9 billion within the next few decades.

The report calls for swift and decisive action from the federal government and state authorities, emphasising the need for updated and strengthened building codes. Regions such as coastal Queensland and Western Australia, currently not fully covered by cyclone-proofing standards, urgently require updated regulations. Such standards could dramatically reduce the damage from severe storms and cyclones.

The good news? Each dollar invested in resilience now can save up to $11 in disaster recovery costs. By proactively improving building standards, infrastructure, and community education, Australia can significantly lower its future financial exposure to climate disasters.

Practical Steps Towards Climate Resilience

The Climate Change Authority’s report outlines several critical actions Australia must take to safeguard homes and communities:

1. Strengthening Building Codes
 Upgrading construction standards to ensure all homes in cyclone and flood-prone areas can withstand extreme conditions is essential. Such measures can reduce property damage and protect homeowners from skyrocketing insurance premiums.

2. Coordinated Infrastructure Investment
 Investing in climate-resilient infrastructure—such as upgraded drainage systems, flood mitigation structures, and reinforced public facilities—provides broad community benefits beyond mere disaster prevention.

3. Improved Public Education
 Empowering Australians with better information allows homeowners to make informed decisions about property investments and disaster preparedness. Homeowners can proactively mitigate their risks through steps such as home retrofitting and ensuring they hold appropriate insurance coverage.

The Ongoing Problem of Underinsurance

Underinsurance, where properties are inadequately covered for their actual rebuilding costs, already poses a significant threat. With climate change increasing both the frequency and severity of natural disasters, the financial risk of underinsurance multiplies dramatically.

Rising construction costs, labour shortages, and more stringent building regulations mean that older insurance policies may no longer offer adequate protection. Regular insurance reviews, guided by expert consultants like Business Insurance Consulting, are essential to avoiding costly gaps in coverage.

How Business Insurance Consulting Can Help

Navigating the complexities of insurance in an era of climate change can be overwhelming. Business Insurance Consulting provides expert guidance and personalised solutions tailored to the specific climate risks you face.

Here’s how we help:

  • Detailed Risk Assessments: We carefully evaluate your home’s location, construction, and exposure to climate risks to determine your insurance needs.
  • Tailored Insurance Policies: We ensure your home insurance policy reflects the current and future climate risks in your area, preventing underinsurance and unnecessary financial exposure.
  • Expert Claims Advocacy: If disaster strikes, we support you throughout the claims process, ensuring a swift and stress-free resolution.
  • Ongoing Policy Reviews: Climate risks evolve, and so should your coverage. We provide regular policy updates to ensure your protection remains robust and effective.

Real-Life Scenario: Why Adequate Insurance Matters

Consider the scenario from the NSW Mid North Coast floods in May 2025. Homeowners who held comprehensive insurance were able to rebuild and recover efficiently, receiving essential support during a challenging time. In contrast, those with inadequate or no insurance faced catastrophic financial consequences, often unable to fully restore their homes and lives without substantial personal debt.

This stark contrast underscores the importance of having comprehensive and accurate insurance coverage tailored to your specific risk profile.

The Road Ahead: Building a Resilient Australia

With nearly 600,000 Australian homes potentially facing uninsurability within five years, the need for immediate action and proactive adaptation has never been more apparent. Practical strategies, including improved building codes, infrastructure investment, and public education, must be at the heart of Australia’s response to the climate crisis.

At Business Insurance Consulting, our mission is to ensure that you have robust and reliable insurance coverage, providing you with peace of mind, regardless of how uncertain the future may seem.

Australian Catastrophe Losses Fall to Historic Low: What it Means for Your Insurance

Australia’s Insured Catastrophe Losses Hit 20-Year Low, Insurance Insights.


Australia’s insured catastrophe losses have dropped to their lowest levels in two decades. Learn what this means for insurance premiums, underinsurance risks, and how Business Insurance Consulting can help protect your assets.

Australian Catastrophe Losses at Historic Low, But Risks Remain

Australia’s insured catastrophe losses dropped dramatically last year, reaching their lowest levels since 2004, according to Aon’s latest Climate and Catastrophe Insight report. In a notable break from decades of severe weather events, Australia experienced no officially declared catastrophe events in 2024, marking the first catastrophe-free year recorded by the Insurance Council of Australia (ICA) since 1982.

However, despite this welcome news, experts warn Australians not to become complacent. Climate risks, underinsurance, and premium affordability remain critical issues that still demand attention. At Business Insurance Consulting, we help Australians navigate this changing insurance landscape, ensuring that homes, businesses, and personal assets remain adequately protected against future events.

A Welcome Respite from Extreme Weather Events

The sharp reduction in insured catastrophe losses, from more than $3.6 billion in 2023 to just $500 million in 2024, is significant. As Aon’s Asia-Pacific head of climate analytics, Tom Mortlock, highlighted, the previous years saw record-high insurance losses, making last year’s decline particularly notable.

Australia and New Zealand’s catastrophe-free year contrasts sharply with the global picture, where insured losses from natural disasters soared to approximately US$145 billion (AU$224 billion), making it the sixth-costliest year globally. Major international events, such as Hurricane Helene in the United States, the Noto earthquake in Japan, and severe flooding in Spain, underscore the ongoing global vulnerability to extreme weather events and natural disasters.

This temporary drop in catastrophe events in Australia, while reassuring, doesn’t mean Australians should relax their vigilance. Past events such as the catastrophic bushfires, devastating floods, and intense storms remain stark reminders of our vulnerability.

Why Australians Shouldn’t Become Complacent

While the significant decrease in insured losses offers temporary relief to policyholders and insurers, it’s essential to recognise that climate risk remains a substantial and growing threat. Experts predict that climate change will continue to increase both the frequency and severity of weather events, even if last year was unusually quiet.

The risk of complacency is substantial, particularly given that Australia continues to struggle with underinsurance and affordability issues for premiums. Aon’s Dr Mortlock notes that many Australians remain underinsured, unaware that their coverage may be insufficient to fully cover the costs of rebuilding after significant damage or loss.

Further, despite the recent reprieve, insurance premiums are not necessarily declining. Due to past disasters and ongoing risk reassessments, many Australians continue to experience rising premiums. As extreme events become more intense and frequent in the years to come, maintaining affordable insurance will remain a significant challenge.

Underinsurance: The Hidden Risk

One of the primary concerns highlighted by the Aon report and other industry analysts is the widespread problem of underinsurance in Australia. Many Australians underestimate the actual cost of rebuilding their homes or businesses after a disaster. Rising building costs, inflation, and increased regulatory requirements following a disaster often render previously adequate coverage insufficient.

Underinsurance can leave Australians exposed to significant financial hardship after even a modest disaster. Despite fewer catastrophic events last year, the risk of severe loss due to inadequate coverage remains a very real concern. Policyholders must regularly review their coverage limits to ensure that their policies accurately reflect current market conditions and actual rebuilding costs.

At Business Insurance Consulting, we actively guide our clients through this process, providing them with tools, market insights, and expert advice to ensure their insurance coverage remains accurate, comprehensive, and cost-effective.

Rising Insurance Premiums: Why Costs are Still High

Even with fewer catastrophic events, insurance premiums have not shown signs of a substantial decline. Past losses, especially the record-breaking $3.6 billion in insured catastrophe losses in 2023, have a lingering impact on insurers’ premium calculations.

Insurance providers must balance the risks they carry, which are influenced not just by immediate events but also by long-term trends and climate projections. The global reinsurance market also affects Australian premiums. Events like Hurricane Helene in the US and severe floods in Europe increase global reinsurance costs, which in turn trickle down to Australian policyholders.

As a result, premium affordability remains a critical challenge for both residential and commercial insurance buyers. It highlights the importance of working with specialists, like Business Insurance Consulting, who can leverage market access and expert negotiation to secure comprehensive yet affordable coverage.

Investing in Resilience: A Long-Term Solution

Aon’s Climate and Catastrophe Insight report emphasises that resilience-building remains key to managing future risks. Investments in mitigation measures—such as storm-resistant construction, improved drainage systems, and wildfire risk management—can significantly reduce damage from future events and ultimately lower premiums.

Australian homeowners, businesses, and insurers alike need to prioritise resilience and mitigation strategies as core components of their risk management plans. Government incentives and industry collaborations aimed at enhancing resilience can also play a crucial role in ensuring that insurance remains affordable and accessible.

Business Insurance Consulting can assist policyholders by recommending proven risk reduction strategies, negotiating better premiums, and ensuring coverage aligns with real-world threats. We help clients understand their vulnerabilities, make informed decisions, and adopt proactive strategies to protect their assets.

Building Protection into Your Future
