Key Takeaway

Home insurance premiums in high-risk Australian areas have surged by up to 50%, driven by increased natural disaster claims, rising reinsurance costs, and climate change impacts. Many homeowners are considering dropping their cover to save money, but this creates severe financial exposure. Going uninsured or underinsured leaves you personally liable for the full cost of rebuilding after a disaster, and most mortgage lenders require adequate building insurance as a loan condition.

Why Home Insurance Premiums Are Rising Sharply

Australian home insurance premiums have climbed dramatically in recent years, particularly in areas exposed to cyclones, floods, bushfires, and severe storms. According to the Insurance Council of Australia, the frequency and severity of natural disaster events have increased significantly, resulting in billions of dollars in claims that insurers must pay out.

When insurers face higher claims costs, they adjust premiums to maintain their financial stability and meet regulatory capital requirements set by the Australian Prudential Regulation Authority (APRA). As explained in foundational texts such as Principles of Finance, insurance pricing fundamentally reflects the expected cost of claims plus operating expenses and a margin for uncertainty. When disaster risk rises, premiums follow.

Reinsurance costs have also escalated. Reinsurance is the insurance that insurers buy to protect themselves against catastrophic losses. Global reinsurers have repriced Australian risk upward in response to the country’s mounting disaster losses, and these increased costs flow directly through to homeowners’ premiums. Properties in cyclone-prone North Queensland, flood-affected regions of New South Wales, and bushfire zones across multiple states have seen the steepest increases, with some areas experiencing premium jumps of 50% or more over a two to three year period.

The Underinsurance and Non-Insurance Problem

Faced with unaffordable premiums, a growing number of Australian homeowners are making the risky decision to reduce their cover or drop home insurance entirely. ASIC’s MoneySmart service warns that underinsurance and non-insurance expose households to catastrophic financial loss.

If your home is damaged or destroyed and you have no building insurance, you bear the full cost of repairs or rebuilding yourself. For most Australians, this represents hundreds of thousands of dollars they simply do not have. Even partial underinsurance (insuring for less than the true replacement cost) leaves a significant gap that you must fund out of pocket after a disaster.

Beyond the financial exposure, mortgage lenders universally require borrowers to maintain adequate building insurance as a condition of the loan. If you drop your cover or let it lapse, you breach your mortgage contract, and the lender can demand immediate repayment of the full loan balance or arrange cover on your behalf (at a higher cost, which they add to your loan). Voluntary non-insurance is not a viable option for anyone with a mortgage.

What Is Driving Abandonment of Cover

The decision to abandon or reduce home insurance is almost always driven by financial stress. When premiums consume a large portion of household income, particularly for retirees on fixed incomes or families in regional areas with lower wages, affordability becomes the overriding concern. The immediate cash flow relief from skipping an insurance payment feels tangible, while the risk of a disaster (which may not have occurred in decades) feels abstract and distant.

However, the Insurance Council of Australia has repeatedly emphasised that the risk is real and growing. Climate change is increasing the frequency of extreme weather events, and properties once considered low-risk are now facing elevated exposure. Abandoning cover precisely when risk is rising compounds the problem: the households most likely to need insurance are the ones cutting it to save money.

Options for Homeowners Facing Premium Increases

Before abandoning your home insurance, explore these strategies to manage costs while maintaining essential cover:

Shop around annually. Premium increases are not uniform across insurers. Obtain quotes from multiple insurers each year, as a competitor may offer substantially lower pricing for the same level of cover. Use comparison websites and contact insurers directly, ensuring you compare equivalent cover (same sum insured, same excess, same inclusions).

Increase your excess. Agreeing to pay a higher excess (the amount you contribute to any claim) reduces your premium. This shifts more of the small-claim risk to you, but maintains full cover for major losses. A higher excess makes sense if you have savings to cover minor damage yourself.

Review your sum insured. Ensure your sum insured accurately reflects the cost to rebuild your home (not the market value or sale price). Overinsuring wastes premium, while underinsuring leaves you exposed. Most insurers offer a sum insured calculator, or you can obtain a professional valuation from a quantity surveyor.

Implement risk mitigation measures. Some insurers offer premium discounts for homes with bushfire-resistant construction, flood barriers, secure locks, smoke alarms, and monitored security systems. While these upgrades require upfront investment, they can reduce premiums and genuinely lower your risk.

Consider switching from agreed value to market value cover. Agreed value cover pays a fixed sum insured regardless of actual rebuilding costs, while market value cover pays the cost to rebuild at the time of loss (up to the sum insured). Market value policies are often cheaper, though they carry the risk of underinsurance if your sum insured is too low or building costs spike after a widespread disaster.

Seek government or industry assistance programs. In some high-risk areas, government initiatives or industry schemes may offer subsidies, reinsurance pools, or alternative cover arrangements to improve affordability. Check with your state government and the Insurance Council of Australia for current programs.

The Broader Implications

A wave of homeowners abandoning insurance creates a systemic risk. After a disaster, uninsured households require government assistance and emergency relief, shifting costs from the insurance market to taxpayers. Communities with high rates of non-insurance recover more slowly, as residents lack the funds to rebuild promptly. The problem is particularly acute in regional and remote areas, where premiums are highest and incomes lowest.

Policymakers, insurers, and regulators are grappling with the long-term sustainability of home insurance in high-risk areas. Potential solutions include government-backed reinsurance pools (similar to the Cyclone Reinsurance Pool introduced in 2022), land use planning that restricts development in extreme-risk zones, and mandatory minimum cover requirements. However, no single solution addresses affordability and risk simultaneously, and the issue remains one of the most challenging in Australian insurance.

General Advice Warning

This article provides general information only and does not take into account your personal objectives, financial situation, or needs. Home insurance products, premiums, cover terms, and exclusions vary significantly by insurer, location, and property characteristics. Before making any decision about home insurance, read the relevant Product Disclosure Statement (PDS) and Target Market Determination (TMD), compare quotes from multiple insurers, and consider obtaining personal advice from a licensed insurance adviser or financial planner who can assess your individual circumstances. Going uninsured or underinsured creates severe financial exposure; seek professional guidance before reducing or cancelling your cover.
