Sunfish if you are doing the job properly there are obvious reasons why you can’t do your landing checklist before you takeoff. Doing your landing briefing before takeoff is an entirely different part of the operation. Haven’t done the sector for a while but ATC would issue the STAR into SYD when issuing the SID out of CBR. The sector from AVV to MEL is not a challenge for a competent crew. If it’s a ferry then you don’t even bother using the AP.
