Billion-Dollar Hail: Australia’s November Storms Trigger Staggering $1.78bn Industry Loss
BRISBANE/SYDNEY — The financial toll of the violent weather systems that tore through Australia’s East Coast in late 2025 is coming into sharp focus. PERILS, the independent Zurich-based organization that provides industry-wide catastrophe insurance data, has officially released its initial loss estimate for the Severe Convective Storms (SCS) that battered Queensland and New South Wales between November 21 and November 27, 2025.
The numbers are sobering: PERILS estimates the total insurance market loss at A2.66billion(approximatelyUS1.78 billion). This massive figure places the November outbreak among the top five most destructive convective storm events in Australian history over the last 60 years, highlighting a worrying trend of increasing frequency and intensity in atmospheric volatility.
A Month of Atmospheric Fury
The November storms were not an isolated incident but rather the second “billion-dollar” event to strike the region in a single month. Coming on the heels of destructive October storms, the November system benefited from “optimal meteorological conditions” for extreme weather.
For nearly a week, a corridor stretching from Brisbane to Sydney was hammered by a series of thunderstorm cells. These were not typical summer rains; they were high-energy convective outbreaks that produced:
- Tennis-ball-sized hail (and larger) in suburban Brisbane.
- Damaging wind gusts exceeding 100 km/h in localized areas.
- Flash flooding resulting from intense, concentrated rainfall.
According to Darryl Pidcock, Head of Asia Pacific and Cyber at PERILS, the destruction far exceeded previous benchmarks. “This was a significantly more destructive event than the October storms,” Pidcock stated. “Hailstones the size of tennis balls caused substantial damage to residential roofs, commercial facade claddings, solar panels, and thousands of motor vehicles.”
The Economic Ripple Effect: Property and Motor Hull
The A$2.66bn estimate covers two primary sectors: Property and Motor Hull lines of business.
- Residential Damage: The modern Australian home is increasingly equipped with solar panels and high-end facade materials. While sustainable, these components are highly vulnerable to large-scale hail. The November event saw a record number of claims for shattered solar arrays and compromised roofing systems.
- The Motor Crisis: Car dealerships and private owners in the Brisbane-Sydney corridor bore the brunt of the “hail cannons.” Thousands of vehicles were declared total losses due to extensive denting and smashed windscreens, further straining the regional automotive supply chain.
Why the Costs Are Skyrocketing
Experts point to a “triple threat” driving these record-breaking losses:
- Urban Density: As the population grows between Brisbane and Sydney, more assets (cars, homes, businesses) are placed in the direct path of historical “hail alleys.”
- Climate Adaptation Gaps: The Actuaries Institute recently warned of chronic underinvestment in climate adaptation. Many structures are not built to withstand the impact of 5cm+ hailstones, leading to systemic failures during SCS events.
- Inflationary Pressures: The cost of building materials and automotive parts has risen sharply, meaning each individual claim costs insurers significantly more than it did a decade ago.
The Reinsurance Outlook
This event will likely trigger significant payouts from the Australian Cyclone Reinsurance Pool and private reinsurance treaties. As insurers face their second billion-dollar payout in 30 days, the industry is bracing for a potential hardening of premiums for residents in high-risk postcodes.
PERILS has indicated that they will release an updated, more granular market loss estimate on February 27, 2026, once more claims data has been processed from the affected insurers.

Australia Severe Storms & PERILS Loss Estimates: Frequently Asked Questions
Q1: What exactly happened during the November 2025 storm event? Between November 21 and November 27, 2025, a series of severe convective storms (SCS) battered the East Coast of Australia, specifically targeting regions between Brisbane and Sydney. The weather systems were fueled by optimal atmospheric conditions that produced “giant hail” (some measured up to 14 cm in diameter), destructive wind gusts, and intense flash flooding.
Q2: What is the current insurance loss estimate for this event? As of January 9, 2026, PERILS AG has released an initial industry loss estimate of A2.66billion(approximatelyUS1.78 billion). This figure covers claims from both property and motor hull lines of business. It is currently ranked as one of the top five most expensive convective storm events in Australia over the last 60 years.
Q3: How does this compare to the storms in October 2025? The November event was significantly more destructive. While the October 2025 storms resulted in an initial loss estimate of A$1.1 billion, the November outbreak doubled that figure. The primary difference was the size of the hail; November saw “tennis-ball-sized” hail in densely populated Brisbane suburbs, leading to widespread structural damage that the earlier storms did not produce.
Q4: Which areas and assets were hit the hardest? South East Queensland bore the brunt of the most intense activity, particularly on November 24th. The most significant damage was reported in:
- Residential & Commercial Property: Massive damage to roofs, facade claddings, and skylights.
- Solar Infrastructure: Thousands of solar panels were shattered by giant hail.
- Motor Vehicles: A “catastrophe-level” number of motor hull claims due to smashed windscreens and heavy denting.
Q5: What is a “Severe Convective Storm” (SCS)? An SCS is a meteorological term for intense thunderstorms characterized by strong updrafts. These storms are the primary drivers of large hail, tornadoes, and “downburst” winds. In Australia, they are most common between September and March when solar energy is at its peak.
Q6: Why are these losses reaching “billion-dollar” status so frequently now? Darryl Pidcock, Head of PERILS Asia-Pacific, noted that this is the second billion-dollar event within a single month. Factors contributing to the rising costs include:
- Urban Sprawl: More high-value assets (homes and cars) are located in historical “hail alleys.”
- Vulnerable Technology: The widespread adoption of solar panels adds a fragile, expensive-to-replace asset to most rooftops.
- Inflation: The rising cost of building materials and automotive parts has increased the “per-claim” cost for insurers.
Q7: When will the final loss figures be known? The current figure is an initial estimate. Following the standard reporting schedule, PERILS will provide an updated market loss estimate on February 27, 2026. This three-month lag allows insurers to process the bulk of claims and provide more accurate data on the total financial impact.
Q8: Will this affect my insurance premiums? While individual premiums depend on many factors, the “clustering” of multi-billion-dollar events often leads to a “hardening” of the insurance market. This may result in higher premiums or increased deductibles for residents in high-risk zones along the East Coast.
