Greens Leader Christine Milne will move in the Senate to defeat the government's plan to abolish investment in renewable energy and set up a double dissolution trigger.
"This crash or crash through Prime Minister is set to crash over his global warming denial," said Greens Leader Christine Milne.
The Greens have received advice from the Clerk of the Senate which indicates a first double dissolution trigger can be achieved before the new Senate takes its place on July 1 by bringing on a second vote on the repeal of the Clean Energy Finance Corporation (CEFC).
Senator Milne will move to guarantee a vote on the CEFC repeal bill before the new Senate comes. The bill will be defeated again and therefore set up a double dissolution trigger.
"The Greens are ready for an election over the Prime Minister's global warming denial and his brutal budget," said Senator Milne.
"If the Prime Minister refuses to follow through on his threats for a new election the unpopularity of his brutal budget and global warming policy sham will be fully exposed once and for all. He will be lame duck.
"The Australian people didn't sign up for Tony's global warming denial or his brutal budget. They now see through his three word slogans.
"It's clear Tony Abbott does not have the skills to negotiate with the cross bench in the Senate, huge parts of his agenda will be blocked.
"The Greens won't entertain any compromise on our values in order to allow the Abbott government to govern a so-called ‘stable government'.
"We expect either a new election if the PM has the ticker for it, or, a completely lame government, shackled by a Prime Minister incapable of dealing with the hand he has been dealt with in the Senate.
"As the Prime Minister's agenda grinds to a halt in the Senate, the Greens will refocus efforts on grassroots campaigning on the threat of global warming and against the cruelty of Abbott's agenda as we prepare for an early election."
