Canberra members of the embattled CFMEU will hold a rally for "democracy" on August 27, following a decision to place all branches of the union into administration.
Attorney-General Mark Dreyfus announced on Friday that all branches of the construction union, including those in the ACT and WA, would be placed into administration immediately, following the passage of new laws this week.
"I have determined a written scheme of administration and the General Manager of the Fair Work Commission has appointed Mr Mark Irving KC as the administrator and contacted Mr Irving to notify him of his appointment," he said in a statement.
Ahead of the announcement on Friday, acting ACT secretary Michael Hiscox said the union had been holding meetings with members at building sites and depots across the ACT.
"Members have overwhelmingly endorsed a rally to support democracy for CFMEU members," he said.
"The government can threaten us with retrospective fines and jail time. It will not work. We won't be bullied or intimidated.
"Our union belongs to CFMEU members, not to politicians."
Mr Hiscox said members had raised issues including how they would continue to organise, and whether the union would continue to be affiliated with the Australian Labor Party.
In a post to Facebook on Friday morning, the CFMEU ACT branch announced the rally would take place in Woden at 11am on Tuesday, August 27.
"We encourage all members of the community to attend. CFMEU members deserve control over their Union, the same as any other worker."
Legislation passed through the Federal Parliament on Monday gave the Fair Work Commission General Manager the power to place the union into administration for a minimum of three years.
It follows revelations of alleged standover tactics, kickbacks and organised crime links in the Victorian and other branches.
The ACT branch says it has not faced any allegations of wrongdoing and that it has consistently fought against criminal influences in the local construction industry.
