How many SCs do you need?
EK does not fly from Bne to Akl, you could do it J or what ever subclasses EK uses.
If you go via Syd, you could go F! Can't believe it, but yes, F class from Syd to Akl.
One return trip from Adl to Syd with QF in J/or a subclass of that, and then F from Syd to Akl for me, and I am in SC heaven/haven!
Hard to guage how much SC I will earn though, as the QF website will not allow a listing for First Class, as it says no First Class offered from Syd to Akl. But EK does have it.
Shows how much the QF SC calculating system needs an upgrade.
