Independent MP Andrew Wilkie has claimed the gaming industry is mounting a smear campaign against him because of his calls for tougher laws to target problem gambling.

The federal member for the Tasmanian seat of Denison says he has recently received death threats as well as threats to reveal "compromising photos".

"In the past two days I've received a death threat, been threatened with the existence of compromising photos, and am having my past as a cadet at Duntroon nearly 30 years ago trawled over,'' he said.

Mr Wilkie says he is not surprised the industry would go to such lengths to attack him.

"Two days ago the pokies industry commenced its campaign against my reforms to reduce problem gambling, including a $20 million public disinformation campaign," he said.

"That some in the industry would stoop to a smear campaign against me is unsurprising.

"It says a lot more about the pokies industry than it does about Andrew Wilkie."

A spokeswoman for Mr Wilkie is not saying whether any photos exist, or who made the threats, and Clubs Australia says it is outraged by the claims.

The independent MP says he will not respond to the smears and that he has nothing to hide from his past.

"While I do not intend to give a running commentary about each new accusation, what I will say is I was judged fit to graduate from Duntroon and went on to have a successful military career, reaching the rank of Lieutenant Colonel," he said.

"There's nothing new in this. I described my Duntroon experience in a book I wrote in 2004 [Axis Of Deceit] and again just last month on ABC Radio's Conversations with Richard Fidler.

"Importantly, during my military and subsequent intelligence careers, I was repeatedly security cleared and character checked to the highest levels in the country.

"Further politically and commercially motivated attacks on my character will not be deserving of a reply."

Clubs Australia says it will continue its multi-million dollar advertising campaign against the proposed poker machine laws.

Executive director Anthony Ball has told AM it is ridiculous for Mr Wilkie to suggest the organisation is involved in threats.

"Obviously he's pointing the finger at Clubs Australia and the AHA, we're the ones who are running this campaign. But look, as I said before, if he's been issued a death threat, he should go straight to the police," he said.

Clubs Australia and the Australian Hotels Association launched the advertising blitz this week, claiming the Federal Government's proposed gambling reforms mean people will need to apply for a licence to make a $5 bet.

Clubs Australia is vowing to campaign until the Government backs down, but Prime Minister Julia Gillard says she is determined to put pre-commitment limits on poker machines.

As well as requiring gamblers to nominate how much money they are prepared to lose, daily withdrawal limits of $250 would also be placed on ATMs near gaming machines.

The Federal Opposition says Mr Wilkie should go to the police if he believes he has been threatened and blackmailed.

Liberal backbencher Steve Ciobo has told AM it is unfortunate media releases are being put out about death threats.

"At no time should either blackmailing or death threats be tolerated and I'd encourage Andrew Wilkie to refer the matter to the authorities for appropriate investigation and punishment if that's appropriate," he said.

Mr Wilkie says he will withdraw his support for the Gillard Government if, by this time next year, legislation has not passed that would give the Commonwealth the power to force the states to introduce the restrictions.
