Home Insurance in Australia 2026: Why Premiums Are Rising and How Cover Is Calculated
Home insurance premiums in Australia have risen alongside the cost of repairing and rebuilding damaged homes, and an industry report published in September 2026 sets out the scale of both. Insurers received about 400,000 claims to repair or rebuild homes damaged in declared events between 2022 and 2026, at a cost of $11.3 billion, while the materials used in those repairs rose far faster than general inflation: roof tiles by more than 70%, and windows, plasterboard and concrete by upwards of 37%. Building costs rose by around 30% nationally over five years and by as much as 44% in Queensland and northern Australia. This guide explains how a home insurance premium is constructed, what a sum insured is meant to represent and how rebuild costs feed into it, why premiums differ between regions with different exposure to declared events, and what a policyholder can review on their own policy before a renewal.
Rising premiums rarely happen for a single reason, and the current environment for home insurance in Australia reflects a mix of claims history, construction costs and regional risk factors. Homeowners reviewing their policies in 2026 are likely to notice changes not just in price but in how insurers calculate the value of their cover.
What Do Recent Claims Figures Show?
The September 2026 industry report set out the total value and volume of home damage claims paid since 2022, alongside the declared events they arose from. These figures typically cover storms, floods, bushfires and other weather-related events that triggered large-scale claims activity. When claims volumes rise sharply following a declared event, insurers often adjust pricing models to reflect the increased likelihood of future payouts in affected regions. This pattern has been consistent across several recent underwriting cycles, with claims data feeding directly into how premiums are set for the following year.
Why Are Rebuild Material Costs Increasing?
Repair and rebuild materials have risen faster than general inflation, with reported movements in the cost of roof tiles, windows, plasterboard and concrete. Supply chain pressures, labour shortages in the construction sector and higher transport costs have all contributed to these increases. When material costs rise, the expense of rebuilding a damaged home increases correspondingly, and insurers factor this into premium calculations. This means that even homeowners who have not made a claim may see their premiums rise simply because the cost of repairing or rebuilding their home has increased.
How Does Sum Insured Differ From Market Value?
A sum insured is meant to represent the cost of rebuilding a home rather than its market value, and the gap between the two can be significant. Market value includes land value and is influenced by location desirability, while sum insured reflects only the cost of construction, materials and labour required to rebuild. When building costs rise, this gap tends to widen, and homeowners who have not updated their sum insured in recent years may find themselves underinsured. Reviewing this figure regularly, particularly at renewal, helps ensure that cover keeps pace with actual rebuilding costs rather than lagging behind them.
Are Regional Building Costs Rising Unevenly?
Building cost inflation has not been uniform across the country, with higher figures recorded in Queensland and northern Australia compared to other regions. Factors contributing to this include higher exposure to cyclone and flood risk, stricter building codes in some areas, and logistical costs associated with transporting materials to more remote locations. As a result, homeowners in these regions may notice steeper premium increases than those in areas with lower reported building cost inflation. Insurers typically adjust regional pricing models annually based on updated construction data and claims history specific to each area.
What Should Homeowners Check at Renewal?
A policyholder approaching a renewal can review the sum insured, the excess, the listed perils and any flood or storm inclusions to understand what each setting changes. Increasing the sum insured raises the premium but reduces the risk of underinsurance, while adjusting the excess can lower premiums in exchange for higher out-of-pocket costs during a claim. Checking which perils are listed, and confirming whether flood or storm cover is included or optional, is particularly important in regions with elevated weather risk. Taking time to review these settings each year, rather than automatically renewing, allows homeowners to align their cover with both their budget and their actual risk exposure.
Home insurance pricing in Australia is influenced by a combination of national claims trends and regional cost pressures, meaning premiums can vary considerably depending on location and property type. General benchmarks suggest that annual premiums for a standard home and contents policy can range broadly depending on the state, the sum insured and the level of cover selected.

Understanding the forces behind rising home insurance premiums, from claims data and material costs to regional risk differences, gives homeowners a clearer picture of what drives their annual costs. Reviewing policy settings at each renewal remains one of the most practical ways to ensure cover stays aligned with both rebuilding costs and household budgets.
