The 2015 Holden State of Origin III, at Brisbane’s Suncorp Stadium on July 8, is officially a sell-out.
NRL chief executive Dave Smith said all tickets, including those for standing room areas, had now been exhausted.
This means a new attendance record is likely to be set for a State of Origin series.
More than 80,000 fans attended Origin 1 at ANZ Stadium and a record 91,513 people attended Origin 2 at the Melbourne Cricket Ground.
The previous attendance record for a three-game series was 215,883 in 2013.
Mr Smith said game three in Brisbane could be the biggest State of Origin match ever.
“We have a decider in front of a sell-out crowd at Suncorp Stadium – it doesn’t get much better than that,” Mr Smith said.
“The first two games of the series have been the biggest free-to-air television shows of the year.
“Now Origin 3 is a sell out and we are expecting another huge television audience.
“The support for the series has been phenomenal and I’d encourage fans to watch the decider wherever they can – from the 117 countries where it will be available.
“This will be a game to remember.”
Queensland Rugby League managing director Rob Moore said it would be one of the great nights in Australian sport.
“State of Origin is a magnificent event and to have the decider in front of a sell-out crowd at Suncorp Stadium will be a real event,” Mr Moore said.
“The support for the Maroons – not just from our fans in Queensland but those interstate and even overseas - has been phenomenal over the course of the series and it will be great to finish it off in front of a packed Suncorp Stadium.
“Fans who missed out on a ticket can still take part in the Origin festivities by getting along to the 18th Man bars at Jupiters and Treasury Casinos or by joining the discussion on social media.”
NSWRL Chief Executive, Dave Trodden said the 2015 State of Origin series has been one of the best on record.
“The Blues cannot wait to play in front of a sell out crowd in the decider,” he said.
“The team know that there will be millions of fans watching on television as well so this is shaping as one of the biggest Origin matches we’ve seen.”
