NSW Better Regulation Minister Kevin Anderson says 553 NSW buildings still require detailed assessment over flammable cladding concerns.

This figure includes 153 high-rise residential buildings.

Meanwhile, Victorian Premier Daniel Andrews has warned that lives will be lost unless state and federal governments work together to solve the cladding crisis.

As insuranceNEWS.com.au has previously reported, the Andrews government has committed $600 million to remove combustible cladding from high-risk buildings.

But Mr Andrews says some issues – including the importation, customs and labelling of building materials – are Federal Government responsibilities.

“All of those matters are not handled at a state level,” he said. “They are handled at a national level, so we will continue what have been pretty positive discussions with the Commonwealth Government on those very issues.”
