Ageless prop Petero Civoniceva says Queensland must be ready to quell a desperate NSW side committed to doing "whatever it takes" in Wednesday night's defining State of Origin clash.

The 33-year-old warhorse, who has gone into battle 24 times previously for the Maroons, believes the Blues have resorted to a team for game two with added experience and aggression after their gamble of a rookie-laden side came up short in Melbourne earlier this month.

The additions of Sharks forward Paul Gallen, who missed the first Origin through suspension, fiery Manly back-rower Anthony Watmough and experienced representative campaigner Trent Barrett, give the Blues a completely different look to coach Craig Bellamy's inexperienced side which started so nervously in Melbourne.

Civoniceva believes the fear factor of being remembered as the first NSW side to lose four straight Origin series will light the fuse for a desperate Blues in Sydney, prepared to go to almost any lengths to keep the series alive.

"I can feel the nerves creeping in and the game is still a week away," said the Penrith skipper, who'll be in the thick of the early exchanges that often determine the outcome.

"It'll be all or nothing for them, they'll be willing to do whatever it takes to win.

"We definitely have to be prepared for that and we will have to be ready for whatever comes at us.

"We can't be on the back foot, we have to take them on right from the start."

Comments this week from Bellamy suggesting Queensland winger Israel Folau was coached to take dives and also that Maroons mentor Mal Meninga had "conned" the game one officials suggest it's open warfare for game two.

Both camps kept a lid on saying anything before the first game that could be used as added motivation.

But just 24 hours after the sides were named for the return clash, it appears it's open slather with so much at stake.

Queensland forward Michael Crocker has added fuel to the pre-game tensions by confirming weekend reports that Gallen had squeezed his testicles in last year's third game decider.

While unhappy with the tactic, Crocker was reluctant to speak publicly about the incident or talk up any thoughts of retribution in Sydney on Wednesday night.

Those kinds of unsavoury incidents and the fact NSW must win have Civoniceva on high alert, along with the rest of the Queensland camp.

Vice-captain Cameron Smith said most of the players in Queensland's history-chasing side were in the same boat as the Blues when they were staring down the barrel of a fourth straight series loss in 2006.

"We were facing the same scenario in 2006 after NSW had won the previous three series and everyone pretty much expected us to lose a fourth series," Smith told AAP.

"But we pulled something out of our backside to win the third game decider in Melbourne (16-14) and the series.

"I know they'll have their heads on all week, Craig (Bellamy) will make sure of that.

"They'll be well prepared for this match to make sure they're not a part of history for the wrong reasons."
