[QUOTE=adamwebster]Looking at a ridiculous MR (LHR-LAX-SYD-MEL-SYD-LAX-IAD-LHR) in April. I intend to get to MEL at 09:40 then depart back to LAX at 11:25 on the same day.

Am I correct in assuming that passengers on this flight would clear customs and immigration at SYD as this is the point of entry into Australia?

Do you think that the 1:45 turnaround would be a problem?

You will clear immigration at SYD if your SYD-MEL is a domestic flight. Otherwise, you have to disembark and go through a security check again, but not immigration until MEL.

1:45 won't be a prob either!

Head over to the QF board for more information.
