Police said they would work with the NSW Crime Commission and they have the full support of the NRL.

Dozens of players, officials and members of the public are expected to be interviewed.

Earlier this year, the Organised Crime Squad confirmed it was investigating allegations of match-fixing in two NRL games from last year.

Those games were a round 16 game between the Manly Sea Eagles and the South Sydney Rabbitohs, and a round 24 match between Manly and the Parramatta Eels.

The last Blues team to visit Origin's most intimidating arena were decimated in a 52-6 record flogging and for the must-win Game Two on Wednesday night seven players will face a sea of some 50,000 Maroons for the very first time.

Five-eighth James Maloney is the only member of the NSW backline to have played a single Origin game in Brisbane while in the forwards debutants Jack Bird and Tyson Frizell have been handed Origin's toughest introduction.

Speaking at ANZ Stadium at the Blues' captain's run on Tuesday morning, Gallen anticipated the rulebook to be thrown out the window when the two teams come together. 

Gallen also expected debutants Josh Mansour, Matt Moylan, Adam Reynolds and Dylan Walker to fit nicely into the Origin arena and the hurt that comes with it.

"There's a lot of emotion and a lot of passion from both sides. We both love it, we both hate each other and at the end of the day we're trying to hurt each other," Gallen said.
