CFMEU inquiry hears fresh claims as Grace Grace engages barrister

Former industrial relations minister Grace Grace has formally secured legal representation ahead of her appearance at Queensland's Commission of Inquiry into the Construction, Forestry and Maritime Employees Union (CFMEU).

According to the Commission's website, barrister Adrian Duffy KC has been granted leave to appear on Ms Grace's behalf. Such approval is typically provided to individuals or organisations with a direct interest in proceedings, those who may face adverse findings, or those able to assist the inquiry on specific matters.

The inquiry has previously heard allegations that Ms Grace threatened contractors working on a major infrastructure project, suggesting contracts could be terminated if they refused to engage with the union. Additional evidence presented to the Commission has raised concerns about alleged "regulatory capture" of Workplace Health and Safety Queensland by the CFMEU during her time as minister.

Ms Grace has rejected the allegations but has not yet given evidence. She has indicated she will respond fully when called to appear.

"All the evidence on this issue will come out at the appropriate time," she said last week. "I have not yet been called, but if so, I will then put my side."

The development comes amid broader scrutiny of the union, following the announcement that CFMEU administrator Mark Irving will step down. His departure was raised during Tuesday's hearing.

Counsel assisting the inquiry, Eddy Gisonda SC, said that while Mr Irving had suggested the union was entering a "rebuilding" phase, the investigation in Queensland remained ongoing.

"It is a mistake to think that proper rebuilding can occur without the full understanding that only a commission of inquiry can deliver," he said, expressing hope that incoming administrator Michael Crosby would cooperate fully with the Commission.

Appearing for the CFMEU, barrister Chris O'Grady KC declined to comment when invited by Commissioner Stuart Wood KC.

Tuesday's proceedings are being held within the Brisbane Magistrates Court precinct, where union members gathered nearby alongside the Electrical Trades Union and others to mark International Workers Memorial Day, honouring workers who have been killed or injured on the job.

The inquiry is continuing to hear evidence this week from major contractors involved in the Cross River Rail project.
