Facing a poll showing support for the LNP had dropped behind Labor for the first time since the party's historic landslide win in 2012, Deputy Premier Jeff Seeney admitted that the government may have pushed its massive change agenda too hard, too fast.

It is the strongest reaction the government has had to polls, which have been showing successive drops in support for the past few quarters, to date.

"I think in retrospect, it is arguable that our change agenda was too much, too quick," he said.

"Not for us it wasn't. I'd been 16 years in opposition, 16 years in parliament, 14 years in opposition, I was, like so many of my colleagues, very keen to embark on the change agenda we believed the people of Queensland wanted.

"We now face the challenge of catching up, in terms of explaining to the people of Queensland, what we did and why we did it and the benefits to them."

Mr Seeney said the government did not regret its policies, but conceded it had not done enough to explain what it was doing and why.

The 'bikie laws', which are about to face a High Court challenge, changes to the Crime and Misconduct Commission, political donation rules, and electoral laws have all elicited a negative reaction from the public, including from Tony Fitzgerald, who is held in the highest esteem in Queensland for his role in exposing corruption within the Joh Bjelke-Petersen government.

Mr Seeney reiterated he would be "happy to meet" with Mr Fitzgerald and discuss his concerns.

But he said the public should be more concerned by the actions of Clive Palmer, who has emerged as a growing political force in Queensland while simultaneously acting as the albatross around his former party's neck.

A former Liberal National Party supporter who established the Palmer United Party, Mr Palmer is suing Premier Campbell Newman and Mr Seeney for defamation.

"I am happy to go into an election campaign against Clive Palmer and the political party that he bought," Mr Seeney said.

"And I am happy to make the case on every single day that Clive Palmer would take Queensland back to the 1970s and the sorts of things that Tony Fitzgerald has been warning about.

"No question about that, because that is what Clive Palmer tried to do."

Mr Seeney, who took the press conference as the Premier is on holidays, ruled out both a Cabinet reshuffle before the end of the year and a leadership challenge.

He said the premier had "done the job that the people of Queensland elected him to do" and that he would  "support Campbell Newman forever and a day".

"I think Campbell Newman has been a great premier, he has been a great leader, he's certainly inspired all of us in the Cabinet to pursue the changes that the people of Queensland voted for at the last election," he said.

"... There is no question that the premier will be the premier for as long as he likes and I hope it is for a long time and he will have my support for a long time, because I understand the extent of the job that he has done.

"To come into a situation where a government was in complete meltdown ... and to turn that around in two years and two months to the extent that we have, is an achievement that few people will ever understand and a lot of people will benefit from."
