Don't know about 90k at the G but think it could get 40 or 50k et Etihad. Record Storm crowd in Melb is 33k for the 07 prelim at Etihad and Storm are a lot more popular now then back then.
If you put out a call for like $15 tickets at the G, I think people would flock. Would be huge if Souths had gotten through, but regardless it seems Storm are content/required to play it at AAMI. And fair enough, it'd be an adjustment if they were to move it.
Tickets go on sale next Monday Keyza
