A heads up. I just checked ticketek, it looks like this games been selling well. I don’t know if they’ve opened up ground level in Ponsford Stand however tickets been selling in Q level of Olympic Stand.
I’d say given favourable Sunday slot for families and ensuring Cats fans can attend, being likely a good build up as Country Game, a crowd of 70,000 would be likely. A win on ANZAC Day could mean anything crowd wise.
