Malcolm Turnbull has released video of a nasty exchange on the Gold Coast's Commonwealth Games Village building site in which a trade unionist appears to threaten a construction worker.

Mr Turnbull, who may attempt to pass the Australian Building and Construction Commission bill that was the trigger for the double dissolution as early as today, will point to the vision as evidence of the "thuggery" of the CFMEU.

The footage begins with the union worker – apparently a safety official of some kind – being reprimanded by a Grocon employee over his driving style.

"Just another thing, the way you drove in – not on," the Grocon worker says.

"What are you gonna do about it, you want your job shut down for another two days?"

"You're actually trespassing," Grocon's man points out.

"You know what," says the official, lowering his voice and drawing in close. "I know your phone number, I know where you live, I'm telling you now, if you don't do your job and protect those workers…Do your job. Do your job."

The fellow then reverses his troopie into a safety sign, knocking it flat in the mud, and opens his door a chink to hurl one final suggestion at his sparring partner:

"You better do an incident report."

Grocon, Australia's biggest privately owned construction company, has faced claims that conditions on the Commonwealth Village site are unsafe, with some 10 complaints being made to Queensland's OH&S watchdog over the past 12 months.

Three of those complaints, the Gold Coast Bulletin reported last month, related to injuries or dangerous incidents, with one worker claiming supervisors ignored his request for an ambulance to be called.
