There are signs the government may soon bring on its building industry watchdog laws for debate in parliament.
A Senate committee report, which is needed before debate on the bills goes ahead, was scheduled to be released next Tuesday when parliament is sitting.
But the education and employment committee instead released it on Friday afternoon.
The government-dominated committee recommended the Senate pass the bills as "union officials in the building and construction industry continue to flout the law and deny that an industry-specific focus is required to combat this serious and persistent unlawful behaviour".
Coalition members said the inquiry was an "excessive indulgence", given that a previous inquiry had looked at the bills in depth.

If the ABCC bills are defeated for a second time - as expected - it will provide Prime Minister Malcolm Turnbull with a double-dissolution election trigger.
Labor leader Bill Shorten criticised Mr Turnbull on Friday for not putting the bills on the program for debate.
"Mr Turnbull doesn't even believe in what he's doing enough to put the legislation forward in the coming week of parliamentary sittings," Mr Shorten said.
The prime minister said on Friday the only reason a double-dissolution election was an option was because of the Senate deadlock over the ABCC laws.
Comment was being sought from Senate manager of government business Mitch Fifield.
