The head of the CFMEU administration has resigned less than two years after he was appointed to clean up the embattled union.
Mark Irving KC revealed on Monday he would step down from his role as CFMEU administrator after more than a year spent laying the groundwork for its future.
Since his appointment in August 2024, the Melbourne barrister successfully established control of the union and drove its restructure, according to a statement from the administration.
As the administration entered a new phase, it needed a different approach, Mr Irving said.
"The union is changing its personnel, it is changing its culture, it is regaining its position in civil society," he wrote in a letter to Fair Work Commission general manager Murray Furlong.
"It is imperative that the administration have the right people in the right roles at this crucial time.
"The best person to lead the administration in this phase should be an experienced union professional who has a fundamental commitment to union values and who can drive the necessary culture change and other reforms."
CFMEU NSW executive officer Michael Crosby is set to take over from Mr Irving as he steps back to a senior counsel role within the administration.
"Mr Crosby is committed to continuing to drive change and rebuild a strong and independent union," the administration said in a statement.
The CFMEU's construction and general division was placed into administration in late 2024 after it was accused of corruption and links to organised crime.
Former CFMEU official and bikie Joel Leavitt, one of four men charged over an alleged extortion plot, faced court in March.
Queensland has also launched an inquiry into the CFMEU, led by commissioner Stuart Wood KC.
