The Queensland government has been accused of dragging its feet on a statewide property development review under way for almost 18 months.
The probe into the financial and operational capacity, ethical behaviours and work practices of developers was announced in November 2021.
But it's been dragging on too long, the construction union said on Thursday, and Premier Annastacia Palaszczuk should intervene to speed up the process.
CFMEU state secretary Michael Ravbar claimed the review had been "bogged down by a change-averse bureaucracy and a minister in Mick de Brenni who is a grand master of over-promising and under-delivering".
A spokesman for Public Works and Procurement Minister Mr de Brenni said the review had been extended to allow stakeholders more time for submissions.
"I anticipate I will receive the report soon, with the report to be further considered by government prior to its release," he told AAP in a statement.
The review was designed to further reforms and ensure accountability and financial security within the building industry.
Mr Ravbar said any delay in the review process would be felt by home buyers and renters.
"If Ms Palaszczuk does want to make a real, positive difference in the housing sector she will act to speed up reforms that will make developers subject to the same sort of licensing and regulatory oversight as others operating in the sector," he said.
