Treasurer Tim Nicholls is "the Kevin Rudd" of the Liberal National Party (LNP) who is undermining Premier Campbell Newman, the Queensland Police Union (QPU) president says.

The comment came after the QPU journal reported that several State Government backbenchers were looking to quit the LNP ahead of the state election and had approached the union for support to run as independents.

"Current backbenchers have individually approached this union for support at the next election if they run as independent," wrote QPU vice-president Shayne Maxwell.

Speaking to 612 ABC Brisbane, Senior Sergeant Maxwell said he had spoken to six MPs from the LNP seeking union endorsement, but he refused to name them.

"As I have advised them, we are an apolitical organisation and we don't support any political parties," Senior Sergeant Maxwell said.

"They've expressed that Campbell Newman and [Police Minister] Jack Dempsey are good people but their concerns are with [Treasurer] Tim Nicholls and the Cabinet budget review committee."

QPU president Ian Leavers said the backbenchers were also concerned about Mr Nicholls knocking back funding to the police.

"Every time it goes to the Cabinet budget review committee that Treasurer Tim Nicholls runs, the funding gets knocked back," Mr Leavers said.

"Now he vetoes this - he's playing games and undermining the Premier and the Police Minister.

"What he's in fact doing is playing with people's lives and affecting community safety.

"Tim Nicholls is nothing more than the Kevin Rudd of the LNP ... who seems to be undermining the Premier and police at every turn."

Mr Leavers also said he knew the MPs who had spoken to Senior Sergeant Maxwell were worried about the direction Mr Nicholls was taking the LNP.

"They have said to Shayne that Campbell Newman is a nice fellow ... [and] these MPs believe that Tim Nicholls is undermining Campbell Newman's leadership but they are too scared to speak up," he said.

"It appears this is a deliberate attempt to sabotage the Government by Tim Nicholls because he wants to be premier.

"The issues that Tim Nicholls sees in his Clayfield electorate are - with the greatest respect to the people of Clayfield - not representative a lot of the issues that police see first hand in the rest of Queensland."

'Mischief from the Police Union'

But Mr Newman said it was not true that six of his backbenchers had sought the union's support to become independents.

"It's mischief from the Police Union - that's what I say - it's simply not true and we've well resourced the Queensland Police Service," Mr Newman said.

"I've got an enormous amount of time for them, we've worked very productively particularly with [QPU] president Ian Leavers, but in terms of this commentary I'm afraid it is a bit of mischief."

Mr Newman told State Parliament there must be some sort of union insurrection in the air.

"It's fascinating there's been an outbreak of commentary from people who frankly have no idea about the inner workings of this Government and have no understanding of the significant support that this Treasurer has given over the last two-and-half-years in this Government to the Queensland Police Service," he told the House.

Mr Newman said his Government backed police officers.

"And a person who is right behind them - 100 per cent - is my friend, the Treasurer of Queensland," Mr Newman said.

The LNP state executive has not commented on the matter.

Mr Nicholls said he had complete and ongoing admiration for the hard work and dedication of police officers.

He said the LNP was supporting the Queensland Police Service (QPS).

"We've also in fact supported the QPS request in relation to their safe night out strategy," he said.

"Not only was it the case that funding was brought forward but in fact increased funding was made available, including increased funding for workload for increased drug testing."

Police funding request 'knocked back'

Senior Sergeant Maxwell said the MPs he had spoken to shared "the same concerns that we have".

"We have a large increase in safe night precincts throughout Queensland," he said.

"The Queensland Police Service put a submission in seeking between $10 and $20 million funding to fund these to protect the members of the public ... and unfortunately Tim Nicholls and this budget review committee has knocked it back."

In the police journal, Senior Sergeant Maxwell accused the LNP of employing "faceless men who attacked your industrial rights and limited your pay rises".

"They drafted legislation that passed in Parliament, sometimes without debate and sometimes even overnight, using their numbers to steamroll them," he said.

"Their main aim was to limit the power of unions and to shrink union membership; they even legislated how you pay your union dues."

Labor MP Jackie Trad said it was further evidence of internal division within the Newman Government.

She said disendorsed Moggill MP Bruce Flegg had spilt the beans on the level of internal division in the LNP.

"Bruce Flegg has made suggestions recently that it doesn't matter what backbenchers do and how strongly they advocate for their electorate, Campbell Newman, Jeff Seeney, Tim Nicholls are not listening," she said.

"The faceless men are in charge - the LNP, Campbell Newman, despite what they say are still not listening to Queenslanders and these LNP backbenchers fear they will lose their seats."
