Suncorp expects $350 million hit from supercell storms

Suncorp has shifted swiftly into disaster-response mode following a series of violent supercell storms that carved a path through southeast Queensland and parts of northern New South Wales, leaving thousands of properties and vehicles damaged across a broad swathe of the region.

The insurer confirmed it had activated its Disaster Management Centre in Brisbane soon after the storms hit, deploying customer support teams to the worst-affected suburbs. The weather system delivered giant hailstones — some measuring up to 13 centimetres — alongside destructive winds that toppled trees, downed powerlines and left homeowners facing extensive clean-ups.

By early Monday afternoon, Suncorp had logged more than 6,890 claims, split between approximately 3,060 home claims and 3,700 motor claims. By 4pm yesterday, that number had hit 10,000 - pretty equally split between home and motor. Lodgements were heaviest in Beenleigh, Shailer Park, Manly West, Cornubia, Capalaba, Loganholme, Keperra, Wynnum, Birkdale and Alexandra Hills, pointing to a concentrated damage belt across Brisbane’s southern and bayside suburbs.

Suncorp severe weather meteorologist Andrew Bufalino said the supercell outbreak reflected atmospheric conditions seen during past major events. “The largest hailstones and most substantial impacts occurred along a corridor from Logan Village through Burbank and Manly, where highly dense and spherical hailstones between eight and 13 centimetres were observed,” he said. He added that destructive winds compounded the impacts, with Gladstone recording gusts of 120 kilometres an hour and Brisbane Airport registering 107 kilometres an hour.

For brokers, the scale and location of the losses signal significant demand for triage, early assessment and guidance for clients managing both property and motor impacts. While insurers expect claim numbers to rise as access improves and power is restored, the immediate bottleneck lies in emergency repairs and prioritisation of severely affected homes.

Cath Stewart, Suncorp’s acting executive general manager for home claims customers, urged policyholders not to delay contacting their insurer. “This helps us organise support for customers sooner and helps us manage emergency repairs,” she said. “Our team are working hard to respond to every customer as quickly as possible. We understand how stressful this time is for everyone affected, and we appreciate your patience and understanding while we work through the high number of claims received in such a short period.”

Suncorp has also cautioned residents about the emergence of “disaster chasers” — contractors or third parties who appear in storm-hit neighbourhoods shortly after severe weather events and may present themselves in a way that resembles official insurance representatives. Ms Stewart said households should be wary of unsolicited offers for debris removal, roof inspections or contract-management services, noting that these operators may charge fees that sit outside the insurer’s standard repair process.

Although the Insurance Council of Australia has designated the Queensland event a catastrophe, with thousands of claims lodged across more than 140 postcodes, northern NSW has so far avoided a formal declaration. Nonetheless, damage assessments are ongoing, and insurers expect a second wave of claims as residents return home or gain access to affected areas.

For the insurance sector — particularly brokers navigating property, motor and commercial exposures — the storms are likely to generate elevated claim complexity. Water ingress, structural compromise, business interruption, and large-scale vehicle losses will form part of the broader recovery picture.

With multiple severe-weather systems tracking across the east coast this season, insurers and intermediaries are bracing for sustained operational pressure. Suncorp’s early mobilisation suggests the industry is preparing for a prolonged period of claim intake and community support, with further meteorological instability forecast in the weeks ahead.
