I bet after release they will have different schedules or rotate timezones or whatever. Right now, they also need to have personnel there to monitor and troubleshoot, since it be a beta and all, and I bet you those don't want to work on Aussie time or would be very expensive if they would want to work at those hours ;). What also works against you guys, unfortunately, is that if I'm not mistaken you are playing with the EU region, since those timezones do work out at least a little, there will be more than enough players online for testing purposes so there isn't really any incentive to change the time slots. I sympathize with my fellow gamers from Australia, they always seem to get the short end of the stick, which sucks because they are awesome to team up with.
