NSW have conceded losing the penalty count in seven of the last eight State of Origin clashes has cost them dearly.

The Blues have struggled under the NRL's top referee Tony Archer during coach Craig Bellamy's three series at the helm, winning just one of eight penalty counts in that time.

"Penalties can change games but I'm not saying we didn't deserve them," Bellamy told reporters on the eve of Wednesday's Origin III against Queensland.

"They give you great field position so that's really cost us."

Archer and Shayne Hayne will officiate game three at ANZ Stadium and NSW will be mindful of their discipline.

"At the end of the day what's happened in the past ain't going to help us tomorrow night," Bellamy said.

"We've just got to make sure we're nice and disciplined tomorrow night and hopefully we can win the penalty count but I don't see that as a real big issue."

The Blues' comments also come after the Queensland camp accused them of grubby tactics in the series so far.

NSW captain Trent Barrett said the Blues had no problems with referees.

"We're certainly not complaining, I thought the games have been refereed pretty well," he said.

"Arch does a good job, he's the best referee."

The Blues will complete their final training run at ANZ Stadium on Tuesday afternoon.
