Apparently over 60,000 tickets sold to Brisbane and Adelaide on wednesday alone.
I managed to get my hands on all the tickets i was after

Brisbane Day 1-3
Melbourne Day 1-4 (Day 5 General at the gate only)
Sydney Day 4 (Day 5 General at the gate only)
Overall I was pretty happy with the location of the seats in comparison to my first preference also.
Anybody else snap up tickets through the ACF pre-sale?
