Champion captain Darren Lockyer led Queensland to State of Origin immortality as the Maroons humiliated New South Wales 34-6 in Game II at Lang Park and romped to a record fifth consecutive series win.

Lockyer was simply untouchable in his 32nd Origin appearance as Queensland weathered a storm of reckless tackling and ill-discipline from the Blues to pile on six tries and stamp an indelible mark on the storied interstate rivalry.

The Blues' heavy-handed tactics merely proved to further spark Queensland following a tumultuous build-up to Game II plagued by a racial slur against Aboriginal centre Greg Inglis and an ugly public debate over the eligibility of AFL-bound winger Israel Folau.

Luke O'Donnell was lucky not to be sent off for a spear tackle on Darius Boyd and a head-butt on Dave Taylor in the ensuing melee, instead joining Cronulla enforcer Paul Gallen on report.

The Maroons though enjoyed the last laugh with Folau grabbing two tries and Inglis terrorising the Blues' right-edge defence all night, making his first mark in just the third minute when he opened the scoring with a powerful burst to the corner flag.

"What a wonderful night for the Maroons," hooker Cameron Smith told ABC Grandstand, returning to the side after missing Game I through injury.

"We talked about it all week, that if we turned up and put in a solid performance we had a good chance of wrapping up this series.

"I couldn't ask for a better performance from the boys tonight. You could never picture the scoreline tonight."

Queensland now holds an unassailable 2-0 lead in the three-match series, following a 28-24 triumph in Game I at Sydney's Olympic stadium.

The brilliant Lockyer orchestrated the six-try demolition with a set of precision passes and tactical kicks that utterly bamboozled NSW, the highlight coming in the second half with a reverse cut-out on the run to pick out Folau unmarked on the right wing.

Lockyer drew the Blues' defence up and in with a ghosting left-to-right run and pivoted his body in order to deliver a flat pass for his Brisbane Broncos team-mate's second try.

The Queensland skipper also executed a sublime defence-splitting inside ball to put Billy Slater into space to score five minutes before half-time but the try was harshly ruled back for a forward pass.

With doubts surrounding the 33-year-old's representative future, this was the perfect performance in front of a vocal Queensland crowd which packed Lang Park to its capacity to witness perhaps Lockyer's final stand at The Cauldron.

NSW prop Brett White scored a late consolation to help the Blues avoid a shut-out, while a gritty performance from young half-back Mitchell Pearce may give them some hope for the future.

The Blues' preparations were disrupted by the departure of winger Timana Tahu and assistant coach Andrew Johns amid a racism scandal, with Joel Monaghan drafted in to make his third Origin appearance.

"Things might have been a bit of an interruption down there for NSW but they still had a pretty good side with a good coach," added Smith.

"I thought we were too strong tonight. We played well."

The visitors made a raft of changes following the loss in Game I but Craig Bellamy's new-look side had no answer for the Maroons' slick attack and stout defence with Lockyer ably supported by Australia team-mate Johnathan Thurston.

In addition to Folau and Inglis's tries, Darius Boyd, Willie Tonga and Cooper Cronk all crossed the line with Thurston adding five conversions from six attempts.

Queensland: 34 (I Folau 2, G Inglis, D Boyd, W Tonga, C Cronk tries; J Thurston 5/6 conversions)

New South Wales: 6 (B White try; M Ennis conversion)
