Prime Minister Tony Abbott has been branded a climate-change criminal by the Australian Greens.
Greens Deputy Leader Adam Bandt was attacking the coalition government's draft legislation to repeal Labor's carbon pricing scheme from mid-2014.
"Tony Abbott is a climate-change criminal," an angry Mr Bandt told reporters in Melbourne.
"I hope that the Labor factional henchman won't aid and abet him by voting to repeal this country's clean energy laws.
"The Greens will stand steadfast to protect the Australian people from the climate change criminality of Tony Abbott."
The repeal bill is due to be introduced during the first sitting of the new parliament in November and Mr Abbott has promised electricity and gas bills will fall after the carbon tax is abolished.
But Mr Bandt said not acting on climate change increased the risk of more frequent bushfires.
"This is about protecting the Australian way of life, making sure that when you go camping at the end of the year over the Christmas holidays you don't have to worry about bushfires wherever you go," he said.
Mr Abbott's bill will face opposition in the Senate, where the Greens will hold the balance of power until the changeover in the upper house on July 1 next year, unless Labor supports it.
Mr Bandt questioned whether Mr Abbott would make good on his earlier threats to go to a double dissolution election if the repeal bill wasn't passed.
"We think that when faced with the arguments about taking action on global warming that the Australian people would overwhelmingly reject Tony Abbott in a double dissolution," Mr Bandt said.
"I suspect that he will back away from that threat and chicken out."
