Flammable cladding blamed for London's Grenfell Tower fire may have been used on as many as 12,000 buildings in Queensland, a taskforce has found.
A year-long inquiry by the taskforce into 28,000 buildings constructed or renovated since 1994 has found 880 require further investigation and at least 70 need rectification work.
The taskforce was set up by the state government after the 2017 Grenfell disaster, which killed 71 people including two Australians, to assess how many buildings carry the aluminium composite panels (ACP).
It is preparing to assess an additional 12,000 privately-owned buildings, including about 1200 residences.
A lack of central data collection and inconsistency of documentation detailing approvals has hindered the work of the taskforce, it said.
"The complexities and challenges that this brings to the identification process means there is a risk that not all affected buildings might be identified or identifiable," the taskforce's report says.
"Private owners and local governments are encouraged to make their own enquiries about the buildings that they control."
Housing and Public Works Minister Mick de Brenni says while it would cost millions to complete rectifications, the government could not put a price on safety.
He told state parliament on Thursday the government had accepted all six of the report's recommendations, including creating a central database of information and an education guide for builders, owners and management bodies.
The report says there "may be as many as 12,000 buildings across the state built since the introduction of ACP into Queensland that will need assessment by the building owner, private certifier or other building professional".
While private owners would be asked to remove the cladding, Mr de Brenni said the government could increase its powers to ensure safety measures were enforced.
The report, tabled in state parliament on Thursday, was prepared by former MP Terry Mackenroth, who died last month.
