Queensland halfback Ben Hunt said he simply stood his ground and it was NSW captain Boyd Cordner that ran into him, creating one of the flashpoint moments of Holden State of Origin II at ANZ Stadium on Sunday.

The NRL Bunker ruled Hunt obstructed Cordner from chasing a James Maloney grubber to score and awarded a penalty try in the 30th minute.

Maroons coach Kevin Walters said he thought the decision was wrong and post-match on the dressing room and Hunt just shrugged his shoulders.

"It is what it is," Hunt said

"I don't think it should have been a penalty try. I didn't really think I took him (Cordner) out that bad. I just stood my ground and he came into me.

"The more I looked at it [on the video screen] and the way the game was going I thought they would send me off [sin bin]."

During the last 10 minutes of the match, when NSW centre James Roberts was sent to the sin-bin after interfering with Gavin Cooper, Hunt tried to keep the Blues pegged to their line as they were down to 12 men.

An attempted grubber into the in-goal early in the tackle count was hit with too much ferocity and rolled dead.

"We just wanted them to stay down there for a couple of sets. I just wanted roll the ball in there for another set and build the pressure," Hunt said.

"It was pretty frustrating when I kicked it too long."

The Dragons No.7 said the Origin arena was a whole new world of pressure, especially for playmakers.

"It's just on another level. You think grand finals are another level up, but this is up one more again.

"It's the best of the best and it's so quick and non-stop out there. You've got to take your chances when you get them and I don't think we did that tonight."

The loss has stimulated the appetite for more to try and master the Origin beast.

"Definitely. I want to be here more. I want to win a series," Hunt said.

"It's my job to get us over the line and I guess I sort of let us down a bit in that area tonight.

"I want to come back and do it again."

It was a medical miracle that front rower Dylan Napa was able to play again so soon after rolling his left ankle in the Roosters-Panthers NRL club game 10 days ago.

He spent most of the intervening week, when he wasn't training at Sanctuary Cove, icing and compressing, stretching and resting the joint.

"We have a pretty good medical staff with Queensland. I've been with the physios all week. I can't thank them enough for getting me out there," Napa said.

"But I'm really happy I could get out there and try to get a win.

"Representing Queensland … there's not much more motivation you need."

Napa said he wanted to put his hand up for the Roosters on Friday night, who travel to Adelaide to play Melbourne Storm in round 16 of the Telstra Premiership.

Napa played the opening 25 minutes and then another 10 minutes late in the second half.

"I didn't go out there seeking a certain number of minutes. I just wanted to do what was best for the team and try to get us on the front foot," he said.

"Executing our sets late in the game, we let them [NSW] off. They were down to 12 players and we couldn't get over that white line.

"It was tough but we're a tight group and we'll stick together."

Fullback Billy Slater, who reached the 30-Origin game milestone in game two, said the Maroons gave it their all for the majority of the match.

"I would like the last 10 minutes again," he said, referring to facing a 12-man NSW side.

"But NSW worked really hard for their victory. If you look at the whole game again we should have scored a few tries in that first 20 minutes. We played some really good football then.

"It could easily have been 24-0 but then again NSW were good enough to stop us.

"They earned their victory down in Melbourne and they earned their series win tonight."
