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 has found 880 buildings require further investigation and at least 70 need rectification work.
The taskforce was set up by the state government in the wake of the 2017 Grenfell disaster, which killed 71 people including two Australians, to assess how many buildings carry the aluminium composite panels (ACP).
It's understood the taskforce is preparing to assess an additional 12,000 privately owned buildings, including about 1200 residential structures.
Housing and Public Works Minister Mick de Brenni has told the ABC that while it would cost millions to complete rectifications, the government could not put a price on safety.
The taskforce's 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 was prepared by former MP Terry Mackenroth, who died last month, and is expected to be tabled in state parliament by the Labor government on Thursday.
