In Australia, boarding starts no earlier than 20 minutes before departure.
Indeed, and check in itself (including checked bags) only close 30 mins before departure. Often QF planes will just be arriving at the gate at the time boarding would start for legacy carriers in some parts of the world (eg. QF512->QF521, 35 mins between scheduled arrival and scheduled depart).
