The NRL has announced that Holden State of Origin III is sold out.

The final tickets for the decider, at Suncorp Stadium on July 12, were sold today.

"This will be arguably the most anticipated Origin clash in the history of the interstate contest, so it will be great to see the house full sign up," NRL CEO Todd Greenberg said.

"We have worked with Suncorp Stadium to maximise capacity. This sort of contest deserves to have as many people watching as possible."

Special extended coverage via host broadcaster Channel Nine will begin at 7pm in Sydney, Brisbane, Melbourne and Adelaide, and 5.30pm in Perth.

Tom Malone, Nine's Director of Sport, said: "With not even standing room left at Suncorp, the best and only place to watch The Decider will be exclusively live and free on Channel Nine. This is going to be the biggest game of rugby league ever."

Fans attending the game are encouraged to arrive early, avoid the queues at the gates and catch the curtain-raiser games, not to mention the spectacular pre-game entertainment program.

The pre-match entertainment, which includes a lights-out spectacular, a special tribute to Johnathan Thurston and a performance from Bernard Fanning, will commence at 7.30pm.

The national anthem will be sung by Paulini, star of The Bodyguard - The Musical.

To avoid delays, fans are encouraged not to bring a bag unless absolutely necessary and plan to arrive early to assist with the security process.

The free travel offer applies from four hours before the main game kicks off. Special services run regularly to the venue in the two hour period leading up to kick-off.

Fans are also reminded that a new Marketplace for Fans is available for Origin III, giving supporters the chance to buy re-sold tickets at their original price.

The new service is designed for people who legitimately can’t attend the event and want to recoup their ticket costs.
