Do I need to clear immigration on separate tickets - HKG
I'm arriving into HKG from KUL on CX around 13:30 and then departing for SYD on QF at 20:15 on a separate ticket.
Do I need to clear customs/immigration and check-in with QF and then go back to departures?
Or could I OLCI for my QF flights and go through transit security in HKG with a printed boarding pass?
