Hi Madbrid
I did my training in Melbourne so start times may be different, but we started at 7am at the earliest, 11am at the latest (they had courses spread out their start times to accommodate the sim).
Theres a couple of class rooms - you will probably be assigned one for your course so you don't have to move around. There's an area behind the TV room you could do some private study, or set up downstairs in the cafeteria (outside of lunchtime theres always plenty of room there). These areas (aside from the classrooms) will be accessible 24/7.
There is also a gym on site you will be able to sign up for once you get here that has all hours access.
Hope that helps
