Claims have surfaced that the Gold Coast’s famed ‘world’s tallest residential building’ is rusting at just six years old.

The 80-storey steel structure is allegedly riddled with corrosion, and the corporate body that represents the apartment owners is now suing Queensland developer Sunland Group for millions of dollars worth of repairs, the Brisbane Times reported today.

The paper says a couple of years ago reports emerged the tower was falling into a state of disrepair, including paint peeling from steel beams, leaving them exposed and rusting.

It is claimed that the tower's steel frame was not coated properly to protect it from corrosion, the defect findings based on a report prepared by a corrosion material engineering and testing consultant.

Sunland has played down the allegations, saying the matter does not impact the structural integrity of the building.
