Residents of the Opal Tower were first evacuated from the building on Christmas Eve after some people heard cracking noises and emergency services were called.

Most had moved back in to the Sydney Olympic Park building when they were told by developers that the entire tower would need to be emptied so their investigations could continue for at least 10 days.

The New South Wales government has requested an urgent update on the investigation.
