Jacqui Lambie will be voting against the construction corruption watchdog legislation, but managed to keep her sense of humour over the double dissolution, saying it was "like a Tatts lotto drawn on a Saturday night".
Speaking on Q&A on Monday night, Lambie said the ABCC bill has "more holes in it than a target at a shooting range".
She said she doesn't buy Commissioner Dyson Heydon's claims that the findings of the Royal Commission into trade union corruption show "widespread and deep-seated" corruption.
"I can tell you what is contained in those secret reports -- there is nothing there that is not normal that happens on the outside and in other places, whether that's even what's going on in our banking and finance sector," Lambie told the audience on Q&A.
"I don't know what the Royal Commissioner is trying to pull here but there is nothing that even resembles a grave threat to the power and authority of the Australian states.
"What I have seen has been very disappointing for $80 million of your taxpayers' money."
Lambie said she would not be blackmailed and the fate of her seat lies in the hands of Tasmanians, as she vowed to keep "the bastards honest" in Canberra.
But when Tony Jones said Lambie could end up with a few senate seats in Tasmania after the senate voting legislation was passed, Lambie -- who has established the Jacqui Lambie Network -- played along.
"With the double D coming up, it will be like the Tatts Lotto on a Saturday night," Lambie said to a crowd of laughter.
Sitting beside Lambie on the panel, Liberal MP Josh Frydenberg argued the construction corruption watchdog bills were "important economic reform".
Liberal Democrats Senator David Lehjonhelm and Senator Ricky Muir both said they would not vote in favour of the ABCC legislation in its current form, while Glenn Lazarus wants the bill to be broadened to cover corruption in banking, finance and politics.
Six crossbenchers need to vote in favour of the bills, otherwise there will be an early double dissolution election on July 2. Prime Minister Malcolm Turnbull announced the move, along with bringing the budget forward in a shock announcement on Monday morning.
