Icon has claimed victory over the $42 million it has spent to date on rehousing, relocating and providing services to Opal Tower tenants after the federal court found insurers Liberty Mutual and QBE should share those costs under the builder's third-party liability insurance policies.

The judgment dated last month meant the insurers would pay about half of what it had spent on residents since they were forced to evacuate on Christmas Eve 2018 from the high-rise apartment tower it had completed less than five months earlier, Icon said.
