Queensland will show a desperate NSW no mercy with a plan to keep their boot firmly on the Blues' throat in Wednesday night's third Origin at Suncorp Stadium.

With the series and the record for successive triumphs secured, Queensland want to make sure NSW start Origin 2010 with a 3-0 series loss hanging over their heads.

NSW haven't been "Maroon-washed" since Paul Vautin's no-names sprung Origin's biggest upset in 1995.

That side was a collection of players filling in for a host of internationals who jumped ship to Super League.

Mal Meninga's current crop boasts a Hollywood backline, with 29-game veteran Darren Lockyer cast in the lead role.

"If we win, it would certainly build a bit of pressure on them having lost four in a row and being whitewashed as well," Storm hooker Cameron Smith said on Saturday.

"We're not going soft. You never go soft on the Blues - ever."

Smith, who has proven something of an Origin ironman and hasn't missed a game since making his debut in the third match of the 2003 series, said it was important Queensland played well in front of 50,000 fans wanting to celebrate.

"It would be a pretty shallow feeling lifting the trophy up (in front of our fans) if we lose that game," he said at Sanctuary Cove resort where the team is based for the weekend.

"If we play well and still get beaten then there's not really much we can do.

"We're not going out and treating it as a dead rubber because Queenslanders don't believe in dead rubbers."

Smith had no idea if Wednesday night's Origin could be Lockyer's last.

"He's a great player and he's done a lot for our state and our jersey and he's the guy who should be our captain when he is playing," offered Smith who led the Maroons to a 2008 series win in Lockyer's absence.

"He hasn't indicated to any of the players or the staff that this is going to be our last game.

"I'd love to be captain of Queensland, but I know as long as Locky is playing and he is available for Queensland he is going to be our skipper."

Karmichael Hunt declared he was ready to play following five days of intensive physiotherapy on his injured ankle.

"It's 100 per cent," said the Broncos custodian who will play his 10th and possibly last Origin with plans to head overseas to play rugby union at the end of the season.

"It was a bit ginger coming into camp but I've had two of three training sessions on it and it's fine."

Hunt proved his value in Sydney in game two when he joined the game earlier than expected after centre Greg Inglis was knocked out by a Trent Barrett swinging arm.

"I never know where (I'm going to play). The last time GI (Inglis) got knocked out so I had to slot into the centres," he said.
