The industry has received about 25 claims linked to the Bondi terror attack, the Insurance Council of Australia says.

“The majority ... are motor claims and a small number are business interruption claims,” a council spokesperson said. “It’s too early to estimate the insurance bill for these claims.”

Insurers are prioritising support for claimants after ICA declared the deadly assault a significant event.

Treasurer Jim Chalmers has declared the mass shooting a terrorist attack, activating the Commonwealth-backed terrorism reinsurance pool.

Pool activation overrides any terror exclusions in businesses’ policies, allowing them to claim for damage.

A spokesperson for the Australian Reinsurance Pool Corporation, which oversees the scheme, said: “We have been in contact with insurers managing the claims and, at this stage, no claims have been identified that would trigger reinsurance coverage.”

The reinsurance pool was introduced in 2003 after cover became unavailable in the private market following the September 11 2001 attacks in the US.

It is backed by a $10 billion government guarantee. The Lindt Cafe siege in Sydney in December 2014 is the only other declared terrorist incident under the scheme.
