Secret documents obtained by the NSW Greens have revealed 340 buildings in Sydney are at risk from flammable cladding.

The list of buildings, obtained under Freedom of Information laws, includes University of Sydney lecture theatres, a child care centre and student housing.

NSW Greens MP David Shoebridge says the Coalition state government is doing nothing to address the issue, and have “handed the whole mess to local councils without providing any new powers or resources to fix it.”
