Public Works Minister Mick de Brenni says former public administrator Jim Varghese will lead the inquiry into the building watchdog’s structure.

The review comes after series of Liberal National Party allegations and Courier-Mail reports about poor culture and decision-making processes at the QBCC.

“Today I can advise my department has commissioned an independent governance review of the independent regulator, the QBCC,” Mr de Brenni told parliament on Tuesday.

“The review will be led by respected administrator Jim Varghese and will ensure the regulator continues to perform in an industry that thrives on innovation and agility.

“It will continue our track record of reform that has delivered the strongest and fairest building and construction industry in the country.”

Opposition public works spokesman Tim Mander said last week the QBCC was failing in its fundamental role of regulating construction work in Queensland.

He said recent revelations that Direction to Rectify Defect works could be “construed as unlawful” was concerning.

Mander also accused Mr de Brenni of “stacking the QBCC board with his union masters”, and called for an inquiry into the watchdog.

“Today the minister said things would continue as ‘business as usual’,” Mander said in a statement on Friday

“He is right: a weekly stuff-up by Mick de Brenni is business as usual.

“The QBCC is broken. It’s time for a commission of inquiry.”
