Tonga v NZ will be in New Zealand, already the NZRL and NRL have started the bidding process with government and venues for the match. I wouldn't be surprised if this game is locked in this side of Christmas with he current momentum.
Having the Pacific Test Double Header at another venue isn't a bad thing. NZ v Tonga should get 30K+ on it's own, so between the three games / two events, we can have 50K-odd watching international Rugby League (not involving Australia) will bode well going against the 60K at Optus Stadium in Perth.
Whether WSS should be the venue is questionable. On the plus sides:
- It's geographically well located for Samoan fans (who will be the largest fan contingent with Tonga not there)
- It's a new shiny stadium, which will have only hosted 5x Events between opening and the Pacific Double Header, so there will be a lot of 'curious' people who will be keen to check it out
The negatives is 30K is possibly a bit too big without Tonga... Arguably over the past few years, you'd say the that Tonga and Samoa would have brought 2/3rds of the crowd, so it's whether Cook Islands will bring many, and whether neutrals would be enough to help bring it back to around the 20K mark at least.
Would like to hope so though... If the NSW Government is prepared to throw some cash / incentives, then I don't think we should say no... just need to get it on sale as early as possible and start pushing it.
