I have no doubt that Ticketek only allocate a few premium bays for priority 1 allocation, knowing full well us die hards will be clamboring for any available, then on Thursday i bet you could log in and find seats available in N9 to N13 areas.
I've been caught out like that in the past Richmond v Nth Melb, got in early and best i could get weere top deck about 20 rows back. Then being curious, logged in on about the Wednesday and first pop got ffronty row centre wing one tier up. Called my group and told them i was in and what seats it was allocating (without member bar codes), they all said buy so i did then sold the other tickets for a smalish loss.
