A Labor MP has likened Federal Opposition Leader Tony Abbott's campaign against the carbon tax to those run by a Nazi propaganda chief.

The Government's carbon tax will start in July next year and then morph into an emissions trading scheme, but the details of the tax and the amount of compensation are yet to be determined.

Mr Abbott today took his anti-carbon tax campaign to Queensland, maintaining his message that Prime Minister Julia Gillard broke a pre-election pledge and that the tax will hit everyone where it hurts - in the hip pocket.

"It is a way-of-life-changing tax, it's an economy-changing tax, and we shouldn't get it without the Prime Minister going to the people again and seeking a mandate," he said.

The Government has accused Mr Abbott of running a scare campaign.

In an opinion piece today, Labor MP Mark Dreyfus described Mr Abbott's so-called "truth campaign" on carbon as Goebbellian.

The term takes its name from the Nazi Germany's propaganda chief, Joseph Goebbels.

Mr Abbott says the comparison is strange, especially after the Government last week accused the Coalition of making offensive comparisons.

Last week the Opposition said Ms Gillard was delusional like embattled Libyan leader Moamar Gaddafi.

"But last week the Prime Minister got very indignant about comparisons with a certain Middle Eastern leader and it's funny that these are the sort of comparisons we're getting from the government," Mr Abbott said.

Mr Dreyfus says he was referring to the nature of Mr Abbott's campaign, not calling him a Nazi.

"I think its a pretty recognised idea in propaganda, Goebellian cynicism," he said.

"It's intended to refer to people that go out, deliberately spread misinformation and think that if they keep spreading the mis-information it'll come to be accepted at fact."

Earlier on Friday, Senator Nick Minchin questioned the impartiality of the government's chief climate change advisor.

He claimed Professor Ross Garnaut is paid by the Government to substantiate its position on climate change.

He also said Professor Garnaut knows very little about the issue.

Climate Change Minister, Greg Combet, says it is disgusting for a Liberal Senator to make such allegations.

"That is a disgusting allegation to make about his personal integrity and his professional conduct of his work," he said.

"Professor Garnault has been a fiercely independent commentator and academic and economist for many years."
