Queensland Police have launched an investigation into indecent act allegations levelled at Brendan Fevola as their Victorian counterparts admitted they bungled a probe into his drunken Brownlow Medal antics.

Almost 12 months after he was shown the door by Carlton following his alcohol-fuelled Brownlow display, Fevola's turbulent AFL career is again hanging by a thread.

The AFL have put their own investigation on hold as Queensland Police late Thursday confirmed they would investigate a complaint lodged against the Brisbane Lions forward from a park BBQ.

"It is alleged that a man performed the indecent act in front of a woman at Wakerley," the police said in a statement.

The two-time Coleman Medallist has been suspended indefinitely by the Lions for allegedly exposing himself in front of a mother of four on Saturday.

Fevola has vehemently denied any inappropriate behaviour and the AFL Players Association has leapt to the full-forward's defence.

"These are serious allegations," AFLPA manager of player relations Ian Prendergast told Radio SEN. "It's also important that we don't jump the gun in terms of Fev's innocence until we have all the information."

Barred from attending the Lions club champion's dinner on Thursday night, it's been reported the controversial spearhead may have left Brisbane to travel interstate.

Queensland police started to take action just hours after Victorian police finally decided they would not charge Fevola.

His infamous drunken behaviour at the 2009 Brownlow Medal function was reviewed but it was decided the police investigator had let the case drag out too long.

"We believe that it would be unreasonable to take any further action on this matter so long after the events," said a Victorian Police spokesperson.

"We accept that the matter should have been dealt with in a much more timely manner, and the police member responsible will be counselled."

For many, Fevola's latest controversy is the last straw in a headline-grabbing 204-match career.

Former Carlton premiership player Mark Maclure hoped he was rubbed out of the game and blamed the Blues for allowing his "shenanigans" to continue over a decade.

"They should have nipped it in the bud earlier but he's a serial pest," Maclure told Fox Sports.

"I hope this is the last time.

"I think our brand has been hurt by this person's actions and it's time to finish it and move on."

AFL operations manager Adrian Anderson has said the league would wait until Queensland Police had investigated the matter before launching their own investigation.

Even if police fail to find evidence of a criminal offence, Anderson said Fevola may still face AFL disciplinary action.

The Lions, facing salary cap pressure due to Fevola's large back-ended contract, would benefit from the AFL deregistering the 29-year-old as it would aid their efforts in re-signing the likes of Jared Brennan, Simon Black and Luke Power.

Fevola said he looked forward to talking to Queensland Police.

"I maintain my innocence and I look forward to giving my side of the story to police as soon as possible. I have nothing to hide," Fevola told the Nine Network's Footy Show.
