Former prime minister John Howard says there'll be a swing to the coalition in Queensland, despite Kevin Rudd's return.

Mr Howard believes the coalition is well placed to pick up seats in Queensland.

But he says he's not taking anything for granted, and voting trends in Queensland can be "volatile".

Mr Howard was in Brisbane on Wednesday to launch the biography of cervical cancer vaccine co-creator Professor Ian Frazer.

The former prime minister will also campaign alongside LNP candidate and former journalist Malcolm Cole in the seat of Moreton, in Brisbane's south.

Mr Howard said he didn't think Mr Rudd's return would produce the swing to Labor some had spoken about.

"I don't think that's going to happen," he said.

"My mail is that there are real prospects for gains for us in Queensland and clearly Moreton is one of those seats."

Mr Howard said Opposition Leader Tony Abbott was doing a good job on the campaign trial.

"He's smart enough to know the campaign still has some two and a half weeks to go and you can never take a campaign for granted," he said.

"I do think he's got off to a very good start."

Mr Howard said there appeared to be a lack of respect for Labor in the community.

"People think it's been an incompetent government and that's its biggest problem," he said.
