i was just checking for fun..
first choose "Terminal 3", then choose flight time "21:00 PM - 21:59 PM" and click "Search" and then you gonna have schedules from around that times' flights..
and why i chose 21:00 - 21:50 PM because seeing Ayu's TA diary, she updated two TA diaries while she was still on the plane on 20:02 & 20:06 PM..so i think boarding time usually is an hour before the flight right?
you can see that most of the flight schedules are going to Melbourne, Auckland, Brisbane and Haneda..she couldn't be go back to Japan coz she was just from Japan right? LOL~
edit: or another flight to Sydney from between 20:00 - 20:59 PM as well
so Melbourne/Auckland/Brisbane/Sydney~
most likely it's Auckland because Max Matsuura is there right now~
