The Insurance Council of Australia’s (ICA) latest figures illuminate a year of unprecedented weather-driven losses in 2025, with insured damages soaring and regional impacts varying widely.
This blog distills the ICA data, explains what drove the spike, and discusses policy implications for resilience and risk management based on three decades of experience studying climate risks and public infrastructure needs.
What the ICA data reveals about 2025 insured losses
In 2025, insured losses reached AUD 4.8 billion—a staggering 727% above 2024—while total claims climbed to 294,000, almost six times the previous year.
The average claim cost rose by 39% to AUD 16,471, underscoring the growing cost of extreme-weather events for households and insurers alike.
These numbers reflect a broad mix of convective storms, floods, and tropical remnants that tested resilience across most states, with Queensland bearing the heaviest burden.
Regional concentration: Queensland bears the brunt
Queensland accounted for more than AUD 4.1 billion of the total losses, as four severe events struck within 12 months.
The scale of impacts across this single state highlights how climate variability translates into concentrated financial risk for communities, insurers, and public services in the Sunshine State.
Top events by claims and losses
The ICA notes several standout events in 2025.
November storms were the costliest, generating 92,900 claims and AUD 1.7 billion in losses, while Ex-Tropical Cyclone Alfred had the highest claim count, with more than 133,000 claims totaling AUD 1.5 billion.
A broad convective storm and hail event across Queensland and New South Wales produced nearly 93,000 claims and AUD 1.78 billion, illustrating how scattered severe weather can accumulate substantial insured costs.
Other notable regional impacts
Beyond the largest events, several regional patterns shaped the insurance landscape in 2025:
- South East Queensland and Northern New South Wales spring storms approached AUD 900 million across 41,200 claims.
- North Queensland floods triggered 11,770 claims, with losses around AUD 316 million.
- Mid North Coast and Hunter region floods produced 14,700 claims totaling AUD 275 million.
- Bondi Event remained comparatively small, with 39 claims and AUD 0.6 million in losses to date.
Broader economic costs and forecasting challenges
Beyond the insured tab, the ICA estimates the broader economic cost of 2025’s extreme weather at over AUD 8.6 billion.
The report emphasizes that such volatility is hard to forecast year-to-year, complicating planning for homeowners, insurers, and governments.
Ongoing supply-chain pressures have amplified rebuild and repair costs, underscoring the interconnected nature of risk, infrastructure, and markets.
Policy implications: investing in resilience
ICA CEO Andrew Hall urged governments to increase investments in mitigation infrastructure—levees, dams, and related flood defenses—to shield vulnerable communities and dampen future rebuild costs.
As climate risk intensifies, proactive resilience measures can reduce economic disruption, shorten recovery timelines, and improve the reliability of critical services during extreme events.
The data support a shift toward integrated risk management that combines engineering resilience with smarter land-use planning and building standards.
Why this matters for communities and decision-makers
From a scientific and public-interest perspective, the 2025 ICA data illustrate not only the growing scale of insured losses but also the geographic concentration of risk.
For researchers, planners, and policymakers, the report reinforces the need for targeted adaptation—whether through robust flood defenses, upgraded drainage, or climate-informed infrastructure investments.
