Queensland coach Mal Meninga has launched a scathing attack on NSW rugby league powerbrokers, claiming they tried to "destroy a dynasty" by undermining the Maroons State of Origin team.

In his Sunday newspaper column, Meninga slams the "very rats and filth that tried to poison a monumental team with lies, personal attacks, arrogance and disrespect."

The coach who guided Queensland to their sixth-straight Origin series victory last Wednesday night over NSW, claimed "faceless men of influence" within the game had decided the Maroons success was "detrimental to the health of the game."

Meninga said discrepancies in judiciary rulings throughout the series, as well as personal attacks on his coaching style were part of a smear campaign that was "malicious and orchestrated."

He also criticised NSW captain Paul Gallen for blaming referees instead of giving credit to a superior team and blasted the media's portrayal of Ricky Stuart's decision to conceal the make-up of his team for game three until an hour before kick-off.

Meninga didn't point the finger at individuals but seemed to vent his anger at Sydney's media, the NSW Blues and powerbrokers within the game itself.

"They are the ones who dragged the spotlight off the game on the field and on to the judiciary with the citing of Johnathan Thurston, and who found five weeks' worth of difference in the identical tackles of David Taylor and Akuila Uate," Meninga wrote in the Sunday Mail.

"They are the ones who criticise Queensland's two closed training sessions as a refusal to promote the game, yet give their blessing to the NSW decision not to name its team until an hour before kick-off - the first time in Origin history.

"They are the ones who have the hide to label Queensland - a team built on the twin pillars of respect and humility - arrogant in victory and whingers in defeat, but offer nothing when their captain places the loss of the series at the feet of the referees, instead of acknowledging superior opponents.

"For them, the self-appointed keepers of the game, rugby league's health depended on NSW winning this year.

"That is what made me and others targets of personal attacks this year, conceived by puppets and driven by smarter people with their own interests at heart."

Meninga's role as Queensland coach was questioned by the media during the Origin series, and the former Maroons and Test great said he knew the people who were behind the criticism.

The 51 year old said he had considered some of the people he believed were undermining him to be friends.

"I know I will never forget what they did," he said.

"They were trying to rot the systems we have put in place for success from the inside out by planting a seed of doubt in the minds of players and staff," he said.

"I was one they chose to attack in a sinister and malicious manoeuvre to remove me from my job.

"It was a disregard and disrespect of what I have worked so hard and so proudly to achieve by branding me a dispensable commodity, an easily replaced cog in a machine they controlled."
