The third game of the State of Origin series has sold out more than two weeks before kick-off at Brisbane's Suncorp Stadium.
NSW defeated Queensland in Origin II last Sunday to send the series to a decisive third match, which will be played in front of more than 52,000 fans next month.
"Thank you to our fans for showing your support for both men's and women's State of Origin," NRL CEO Andrew Abdo said.
"A captivating series will be attended by more than 200,000 fans and will all come down to a decider on July 13."
Queensland fullback Kalyn Ponga is the only player who sustained an injury in game two that prevented him from being named to play NRL this weekend.
The Knights No.1 suffered a head knock but appears in no doubt to line up in the decider.
Queensland five-eighth Cameron Munster and NSW prop Payne Haas picked up shoulder and ankle injuries respectively but both have been named to play for their clubs this weekend.
Felise Kaufusi's ability to line up in Origin III remains under a cloud, however; the Melbourne and Queensland back-rower flew to Los Angeles on Tuesday to be with his father, who has been hospitalised.
Immediately after the Perth clash, Maroons coach Billy Slater said he would resist the urge to make mass changes to his 17.
His NSW counterpart Brad Fittler could alter his own side, though.
Fittler named Jack Wighton NSW's best player after game one and the former Dally M Medallist has now recovered from the bout of COVID-19 that kept him out of Origin II.
Blues stalwart Latrell Mitchell is also a chance to break back into the side, having shaken off a hamstring injury and coronavirus case of his own.
