Across Australia’s five largest capital cities, household insurance costs are climbing to unprecedented highs, with homeowners in Sydney and Brisbane now facing average annual premiums exceeding $3,000 for combined home and contents coverage. The sharp uptick in pricing for both home and car insurance has been linked to three core forces reshaping the market, according to new analysis from leading Australian price comparison platform Compare the Market.
Compare the Market’s research tracked average insurance quote changes across Sydney, Melbourne, Brisbane, Adelaide and Perth, revealing uniform double-digit percentage increases for home coverage nationwide. Sydney homeowners recorded the steepest absolute jump, with average quotes rising $334.01 year-over-year. Adelaide followed closely with a $324.68 increase, while Melbourne saw an average rise of $321.11. Brisbane and Perth were not spared, with average increases hitting $310.62 and $308.71 respectively, pushing annual premiums over the $3,000 threshold for consumers in both cities.
The trend extends beyond property insurance, with car insurance premiums also jumping sharply across all five major capitals over the past 12 months. Melbourne recorded the largest increase for auto coverage, with average quotes rising $285.03 year-over-year, as total motor vehicle theft payouts in Victoria surged to $243 million. Sydney followed with an average $225.74 car premium increase, Adelaide saw a $182.70 rise, while Brisbane and Perth recorded more modest increases of $152.88 and $131.73 respectively.
David Koch, Economic Director at Compare the Market, explained that while many Australian households are now facing hundreds or even thousands of dollars in extra annual insurance costs, the price hikes are not simply driven by insurer profit-seeking. Instead, three interconnected structural factors are pushing industry-wide costs higher.
“The first is persistent inflation, which has driven up the price of every input required to repair or rebuild damaged property – from construction materials to skilled labor and freight,” Koch explained. “By 2025, those cumulative cost increases have made restoring a home far more expensive than it was just a few years ago, and insurers have to adjust their pricing to match that new reality.”
The second major driver is the rising frequency and severity of extreme weather events across Australia. Koch pointed to the catastrophic hailstorms that hit New South Wales and Southeast Queensland in 2024, which alone triggered $1.78 billion in insurance claims. More frequent and intense natural disaster events have forced insurers to increase collective payout reserves, a cost that is ultimately passed to consumers.
Third, Koch noted that structural changes to how insurers calculate and set risk-based premiums also contribute to the current price increases, as firms update their models to reflect the new higher-risk economic and climate environment.
For consumers facing sticker shock on renewal notices, Koch offered actionable advice: many Australian households are overpaying for coverage, and can cut significant costs by comparing policies from different providers. He also urged motorists to review their car insurance policies annually, updating their details to reflect lifestyle changes that could lower premiums – including moving to a lower-risk address, reducing annual driving mileage, or securing a car in a locked garage overnight.
The report adds to growing concerns about rising cost-of-living pressures across Australia, with essential household services continuing to outpace baseline inflation for many families.
