Home insurance in Australia has become a luxury many households can no longer afford. Around 1.6 million households are now experiencing insurance affordability stress, meaning premiums consume more than four weeks of their gross income. The number experiencing stress has jumped 30 per cent in a single year.
The scale of the squeeze is stark. Average home insurance premiums have climbed 51 per cent over five years, rising from $1,940 in 2020 to $2,938 by October 2025. In the past 12 months alone, premiums jumped an average of $343, or roughly 14 per cent. New South Wales has been hit hardest with year-on-year increases of 18 per cent, while the national trend shows costs rising across every capital city and region.
Geographic disparities reveal why the crisis feels worse in some places than others. Darwin records the highest average capital city premium at $4,015, followed by Sydney at $3,964 and Brisbane at $3,872. In high-risk areas such as southwest Queensland, the Northern Rivers region of NSW, and regional parts of the Northern Territory and Western Australia, roughly half of all households face affordability stress. The gap between safe suburbs and disaster-prone ones is widening.
The cost explosion reflects genuine financial pressures on insurers. Victoria's January 2026 bushfires alone generated more than 1,400 claims within weeks, with 30 per cent classified as total losses and insured costs exceeding $200 million. The increasing frequency of extreme weather events, combined with rising construction and rebuilding costs, has forced insurers to reset their risk models upward. Reinsurance costs, which insurers pay to protect themselves against catastrophic losses, have also climbed sharply.
Yet the financial burden is becoming unsustainable for households already squeezed by mortgage rate rises and energy costs. In late 2025, a poll found that 80 per cent of households now worry about their insurance costs, the highest level in a decade. More concerning, 22 per cent of respondents said they might drop insurance altogether if prices continue climbing. That decision exposes homeowners to financial ruin if disaster strikes.
The Australian Competition and Consumer Commission, while monitoring the crisis, has no power to regulate insurance prices directly. However, the Australian Prudential Regulation Authority has flagged a widening "insurance protection gap" as a risk to financial system stability. Half a million Australian properties may become uninsurable by 2030 due to climate exposure, according to recent research.
For households seeking relief, options remain limited. Shopping around between providers can yield savings of several hundred dollars annually, but the competition is narrowing as smaller insurers exit high-risk markets. Some households are reducing coverage limits to lower premiums, a dangerous compromise that leaves them exposed. Government policy reforms were flagged for 2026 with promises of up to $1,200 in annual savings for eligible households, though details remain sparse on who qualifies and when relief will arrive.
