Three day PAX Australia passes were completely sold out but now, while stock lasts, a small amount of these passes have been made available. So if you missed out and you're keen, click on this link quickly!
The reason for the shortfall is this: now that media and PAX Enforcer passes have been approved, the three day passes that those people bought have been refunded, hence the additional tickets. I can't imagine there are too many of these tickets available, but it might be worth checking out if you are in need of a three day pass. Worth stressing: this is strictly a while stocks last situation.
Have at it friends.
