You'll want to bring corporate clothes to wear in ground school til uniform week.
Use a mix and match so you don't have to bring too much stuff. Gym clothes, Pjs, a couple of going out outfits as you'll go for some dinners etc with your group. Jeans and runners for any pracs that require long sleeves and pants (not sure if fire training is still live)
Not sure if accommodation is still apartments with cooking facilities or not. For my group we had apartments in CBD area of Sydney, went home over Xmas, back for a week and had rooms near QF head office, back across for NY, then back to the apartments after NY. It's probably different now, but we didn't share rooms which was nice.
you'll gave to wear "business casual" on your flights to/from as well if I'm not out of date now.
unfortunately my references haven't responded so that's likely me out if the running.
