Katter's Australian Party (KAP) founder Bob Katter has likened Liberal National Party (LNP) election tactics to the propaganda of Adolf Hitler.

The KAP has taken legal action against the LNP in a bid to stop the spread of what it called blatant lies in election material.

Mr Katter said the LNP's election material inferred the KAP made a deal with Labor to form government in the event of a hung parliament.

KAP Gympie candidate Shane Paulger said an application for an injunction against any further untrue statements and distributions by the LNP was lodged in the Brisbane Supreme Court on Friday morning.

"We are submitting an injunction against the Liberal Party to prevent them from spreading more lies to the people of Queensland, such as this pamphlet that's been distributed ... in the Courier Mail today," he said.

But the LNP said the court action was a media stunt and that they would challenge the injunction.

"The LNP have forgotten about integrity and honour. If they can't win with that, they'll win any way they can, and if that includes lies it seems to be the way they're going.

"It's an absolute disgrace and, quite frankly, the voters of Queensland deserve much better.

"It's about time we had some honesty and integrity and I think this new low level that Mr Newman has stooped to needs to be exposed to the community.

"No deals have been done and our party has not got any preconceived ideas of which way we will go if and when we do secure a hung parliament.

"We are very, very concerned [about] the injury done to our party with these flagrant lies that the Newman Government continues to perpetrate.

"We are asking the courts to stop this as of right now and are very hopeful of success today."

Mr Katter said the Coalition had spread similar untruths to campaign against the KAP at the last federal election.

"A lie is effective. Adolf Hitler, of course, said in his book Mein Kampf you tell a lie consistently enough, constantly enough and you will have people believe it's the truth," he said.

"Obviously these people have read that or some similar book."

Mr Katter said the LNP had unlimited corporate finance to spread its election material.

"They go into this election spending tens of millions of dollars when little parties, except for Palmer of course, ... have no money to spend at all to be able to answer the lies."
