The Greens will be calling for a Senate inquiry into Attorney-General George Brandis over what it has described as a "very murky affair" with the West Australian government.
Senator Brandis reportedly struck a deal with WA allowing the state to claw back $1 billion from Alan Bond's collapsed Bell Group earlier this year rather than the commonwealth.
The Greens will be seeking support to hold a Senate inquiry into the "trouble-prone attorney-general" when parliament sits for the final sitting week of the year on Monday.
"His days in witness protection are numbered," Greens senator Nick McKim told reporters in Perth on Sunday.
"We are not going to let him get away with ducking for cover forever."
Labor frontbencher Jim Chalmers labelled Senator Brandis "the walking scandal magnet" and called on Prime Minister Malcolm Turnbull to sack him..
"If these latest very serious allegations are true, then they amount to at least moral bankruptcy and probably corruption," Dr Chalmers told reporters in Brisbane.
"Every time George Brandis comes up with a sackable offence - and there have been many - excuses have been made for him because the prime minister is too weak to sack him."
West Australian senator and government frontbencher Mathias Cormann said he was not aware of the ins and outs of any involvement that the attorney-general may have had in this matter.
"I am aware that the government here in WA, instead of continuing to spend millions of dollars on lawyers' fees, was focused on finding a way to bring this issue to a conclusion," Senator Cormann told Sky News.
