The government will move to bring the carbon tax repeal bill on as the first order of business when the new Senate sits on Monday.

However, the opposition and the Greens say the debate should be left until July 14, when a Senate committee report into the repeal of the carbon tax is due to be tabled.

The argument will be settled in a procedural debate that could consume significant time on the first day of the new Senate before a vote on the carbon tax repeal bill can even go ahead.

The government’s Leader in the Senate, Eric Abetz, said on Sunday that despite the “feisty demeanour” of the new crossbench senators, he hoped they would see the benefit of repealing the carbon tax after months of efforts from Labor and the Greens to “frustrate that agenda”.
