I've recently booked a first reward for the SYD-CHC fifth-freedom flight, leaving in a few months' time (I'm very excited).
I'm yet to book the return leg; I've noticed that it gets back into SYD @ 19:05 - what would the minimum connection time be to make a domestic flight out of SYD? (I'm guessing that 90-105 minutes is too tight to take into account passport control / immigration, collecting luggage, transferring to separate terminal, re-checking-in luggage. I'm also assuming that the luggage can't be sent all the way through to my final destination.)
If it is too tight, I might consider a non-A380 route back (as much as I'd like to take it).
