Bulldogs vs Brisbane, should be a solid 15,000 people there, you'll have nothing to worry about in terms of getting a ticket.
It will definitely not be a sell-out, mate, you've got nothing to worry about.
Yeah, Hamish Harlett Society is right. The match isn't really a 'Big' match, so i'm pretty sure they'l be PLENTY of tickets left.
There are still tickets available for general admission. You can buy them online now. So did you go?
Can you not buy tickets at a booking agent for the match?
