This blog post analyzes the Insurance Council of Australia’s 2025 report on insured losses from extreme weather. It highlights where losses occurred, which events drove the costs, and what this means for communities, insurers, and policy makers.
It distills the data to show how Australia’s weather extremes translated into financial pressure on both households and the insurance sector. It discusses the policy levers that could bolster resilience in the years ahead.
What the ICA data reveals about insured losses in 2025
The ICA’s latest figures show insured losses reached $4.8 billion, a dramatic 727% increase on 2024. Queensland accounted for the vast majority, with more than $4.1 billion in claimed damage across four severe events in the year.
These numbers reflect a year of frequent, costly extremes and a shift in the balance of where losses occur within Australia.
Major weather events driving the costs
Several events dominated the tally, illustrating the two driving forces behind the rising totals: the severity of individual events and the cumulative effect of hail-driven claims that accrue over months.
The year’s most expensive single event was November’s severe storm and hail across Queensland and New South Wales, which generated almost 93,000 claims worth $1.78 billion.
- Spring storms in South East Queensland and Northern New South Wales added nearly $900 million across 41,200 claims.
- Ex-Tropical Cyclone Alfred produced the highest volume of lodgements for a single event, with over 133,000 claims totalling $1.5 billion.
Beyond the headline events, the Insurance Council notes the long-tail nature of hail-driven catastrophes. Claims continue to accumulate over months as repair costs rise and visibility of damages expands.
Costs, claims, and market dynamics
Across 2025, insurers processed roughly 294,000 claims from declared extreme weather events — almost six times 2024’s total. The average cost per claim rose 39% to about $16,471.
When you factor in broader economic impacts, the total cost of extreme weather in 2025 is estimated at more than $8.6 billion.
Australia’s general insurers paid $58.9 billion in claims across 90 million policies in 2025, up 18% year on year.

Implications for policy and resilience
The ICA notes that the scale and unpredictability of severe weather in 2025 highlight an urgent need for strategic public investment in resilience infrastructure to protect vulnerable communities and help stabilize insurance markets.
The data argue for a forward-looking approach that pairs disaster risk financing with durable physical protections.
Mitigation infrastructure priorities
- Levees and flood defenses to reduce inundation in high-risk basins.
- Dam safety upgrades and reservoir management to prevent cascading losses in flood years.
- Floodplain restoration and nature-based solutions to absorb rainfall and slow runoff.
- Early warning systems and weather monitoring to improve preparedness and response times.
- Smart building codes and land-use planning to lower exposure in high-risk areas.
