A fire has broken out at the new Australian Tax Office tower in Box Hill.
The 19-storey office building is currently under construction on Whitehorse Road.
A spokesman from the Metropolitan Fire brigade said the blaze was under control, with about eight appliances on the scene.
He said it was too early to say how much of the building had been burnt.
Construction on the tower began in early 2013, according to developer Grocon. Their website says that the project was due to open next year, becoming home to 1250 staff.
More to come.
