For pay, you're best to look at the new QCCA long-haul EBA which is about to kick in.
The 2022 rates:
Trainee Flight Attendant: $34,639
Flight Attendant - Entry: $46,377
Flight Attendant: $47,264
LH'ers make their money on overnight allowances on top of their salary ($139-$350 for a full 24 hours in port), but that figure is dependent on how you work your roster, what trips you get, and is different for everyone. Hope that helps.
