The CFMEU administrator sent two teams of investigators away, despite their task to uncover corruption in the union.
These teams, assembled to investigate graft, were swiftly disbanded, leaving serious misconduct allegations unaddressed for months.
One source said the administrator was concerned that seeking more powers from the federal government could risk reviving calls for the coalition's Australian Building and Construction Commission.
Former AFP officer Chris Craner was recruited to help investigate wrongdoing at the CFMEU, but the investigation was ultimately abandoned.
The Albanese government's CFMEU reform chief, Mark Irving KC, was responsible for the abrupt abandonment of the anti-corruption teams.
