Asbestos removal in Queensland’s parliamentary annexe has cost the state $300,000, a budget estimates hearing has been told.
Clerk of the Parliament Neil Laurie told an estimates hearing there were unforeseen issues with asbestos within the building's 24-tonne pool, squash court and plant boxes.
Renovations on the seventh level of the 40-year-old building have been delayed due to unexpected heavy rain.
"Quite frankly, there was just asbestos everywhere we went and turned over things," he said.
Construction has had to be halted because it was excessively noisy, while the building of a new government tower across the road has also interfered with the work.
"A contributing cause has been actually the establishment of 1 William Street because it's put a shadow over us and we're not getting much sunlight on level seven," Mr Laurie said.
But the $300,000 cost of removing asbestos was similar to an amount spent in the NSW parliament, he added.
Speaker Peter Wellington said there would always be a requirement for further work.
"We will work within the budget that we have as best we can," he said.
Opposition Leader Tim Nicholls, the former LNP treasurer, acknowledged treasurers were "notoriously tight with these things".
