Who will sing the national anthem? Who won't?
The anthem has attracted a lot of attention during this series, with some players refusing to sing something that doesn't represent them. Of couse, some don't sing simply because they're lousy singers and don't particularly want to expose that on national TV.
Mbye and Gagai clearly aren't singing, but others are giving it the full lip sync.
Aussie Idol winner Guy Sabastian has provided the pre-match entertainment... but all anyone really wants is some footy.
Why do they make Origin pre-game so looong?
Kevin Walters has made a late change in his back-line, bringing Moses Mbye off the bench and into the centres for Michael Morgan.
Ethan Lowe will start for the suspended Matt Gillett among the Queensland forwards.
Kia ora, good evening and welcome to Newshub's live coverage of State of Origin III - rugby league's eternal battle between good (Queensland) and evil (the other guys).
We join this rivalry poised at 1-1, with the Maroons taking out the first meeting at Sunforp Stadium and the boys from south of the border running riot in the return match in Perth.
Both sides have had to make changes for the decider in Sydney, but perhaps the most intriguing match-up through this series has been between coaches Brad Fittler and Kevvy Walters.
After a few bleak years, Fittler inspired the Blues to victory last year with a refreshing approach that seemed to strike a chord with his players.
This year, Walters has proved a man of many moods, refusing to even mention his opponents in the build-up to the opener, but becoming very angry after the capitulation out west.
Which Kevvy will turn up this week?
Perhaps the biggest change to the NSW line-up will see Mitchell Pearce replace injured Nathan Cleary in the halves, teaming up with former Roosters championship-winning teammate Jimmy Maloney.
Across the park, wonderboy Kalyn Ponga hasn't recovered from a calf injury and will be replaced at fullback by Cameron Munster, who usually plays in the halves for Melbourne Storm.
Munster's place in the six jersey will be taken by Corey Norman on debut.
The updated line-ups are:
NSW: 1-James Tedesco, 2-Blake Ferguson, 3-Tom Trbojevic, 4-Jack Wighton, 5-Josh Addo-Carr, 6-James Maloney, 7-Mitchell Pearce, 8-Daniel Saifiti, 9-Damien Cook, 15-David Klemmer, 11-Boyd Cordner, 12-Tyson Frizell, 13-Jake Trbojevic
Interchange: 10-Paul Vaughan, 14-Dale Finucane, 16-Cameron Murray, 17-Wade Graham
Queensland: 1-Cameron Munster, 2-Corey Oates, 3-Michael Morgan, 4-Will Chambers, 5-Dane Gagai, 6-Corey Norman, 7-Daly Cheery-Evans, 8-Joe Ofahengaue, 9-Ben Hunt, 10-Josh Papalii, 11-Felise Kaufusi, 12-Ethan Lowe, 13-Josh McGuire
Interchange: 14-Mose Mbye, 15-Christian Welch, 16-Tim Glasby, 17-David Fifita
