The declaration marks the resolution of a long-running dispute at the 36-storey complex in Sydney Olympic Park. Cracks discovered on Christmas Eve 2018 prompted fears of a collapse, leading to the evacuation of thousands of residents and the closure of the nearby train station and surrounding roads. Police at the time said the tower had moved "1 to 2 millimetres", and further cracks were later found on other levels.
Opal Tower Owners Corporation chairman Shady Eskander, who has led the campaign for repairs and compensation, said the saga was about more than structural defects. "The story is about defects, but really it's about devastation to people's lives when something goes wrong in your home, it completely up-ends you," he said. "It's fantastic to announce that Opal Tower is defect-free."
Mr Eskander said millions of dollars had been spent on rectification work, carried out collaboratively with developer Ecove, backed by Japanese firm Kajina Corporation, engineers WSP, and builder Icon. An engineer's report commissioned by the NSW government in 2019 attributed the cracks to a combination of "design and construction matters, in particular changes made after the original design".
The high-rise, which contains 392 units, is now protected by a 20-year structural warranty, which Mr Eskander described as an Australian-first. All owners have been fairly compensated and all legal matters resolved. Nutan Borkar, who was out of her unit for 11 months after the incident, welcomed the end of the ordeal, saying there was finally "light at the end of the tunnel after a big struggle".
"This is the greatest property comeback story in Australian history," Mr Eskander said in a statement.
