Owners of Sydney’s embattled Opal Tower complex are facing possible financial ruin with no solution to the disaster in sight, a resident says.

The nightmare began on Christmas Eve, when residents of the four-month-old, 36-storey building reported hearing a disturbing, loud “cracking” sound.

Those living in 51 units deemed unsafe to occupy were promptly evacuated, and as investigations are still under way, the cause of the building’s damage is not yet known. chief economist Nerida Conisbee said it was impossible to predict just how much money Opal owners stood to lose, as any potential price drop would depend on whether or not the issues could be resolved.
