Dozens of South Australian buildings require urgent remedial work for flammable aluminium cladding, but the State Government will not say which ones specifically.

A statewide review was launched in mid-2017 in the wake of fatal London's Grenfell Tower fire, identifying around 30 buildings that contain the potentially flammable cladding.

The State Government audit interim report said seven of the privately-owned buildings are at “extreme risk” and require immediate remediation.

Other were assessed as “high risk”, requiring remedial action in the next 12 months.

Tenants could be forced to cover some of the costs of remediation, after the State Government ruled out following Victoria’s lead in putting up hundreds of millions of taxpayer dollars to reduce the fire risk.

Infrastructure Minister Stephan Knoll has refused to identify which buildings are at risk, saying responsibility falls to building owners.

“Security and safety have always been one of the primary reasons that we do not reveal the exact locations of buildings with significant cladding issues in line with other states,” he said.

“We don't want to put a massive sign on the front of a building to say to an arsonist; ‘Come here, and you can wreak havoc’.

“It is our expectation that building owners will notify occupants of their respective buildings and keep them informed throughout the remediation process as appropriate.

“None of these buildings has been assessed as needing to have the occupants evacuated. All of these buildings are buildings in the short-term that are able to be occupied.”

The Minister said building owners have a “duty of care” to notify tenants in affected buildings.

He has left it to South Australian councils to ensure that the owners of private buildings undertake necessary work to reduce the risk.

“The [Department of Planning, Transport and Infrastructure] will be working very closely with councils and building owners to ensure remediation works are carried out and these buildings meet the acceptable standard,” Mr Knoll said.

“The way that we deal with defects in buildings essentially places the responsibility with councils under the Development Act to be able to have that discussion with building owners.

“We firmly expect building owners to take their duty of care seriously and have those conversations with the occupants inside those buildings.

“Targeted recladding of some high-risk areas, in a number of situations, will be sufficient to reduce the life safety risk.”

The Opposition insists the public has a right to know.

CFMEU assistant national secretary Andrew Sutherland said he is “appalled”.

“I can't understand how they can be putting the tenants of those buildings at risk and in the same breath be saying they've got the safety of all South Australians at the forefront,” he said.

“It's two years since the Grenfell fire and here we are — one of the buildings that is publicly owned is still under construction and is containing the flammable [aluminium composite] panels.”
