Because we're pretty League-starved here in Perth! One or occasionally two NRL games a year in recent years is all we get apart from the local comp. We've sold out NIB Stadium several times in recent years (including having the record attendance figure for all sports), and that's just been Souths against Warriors games. With an international game, with the right amount of promotion in the lead-up, I'm confident a 60,000 seat venue here will be filled. Especially if it has nations that have a lot of support here (Australia, NZ, England, South Africa possibly too). Even Samoa / Tonga have seemingly a quite a bit of support here too.
