I am looking to book the following itinerary on QF in business or economy. Can you let me know if this is a valid multi city booking and it's cost for business or economy? There will be stopovers in each city. Is this allowed?
MEL-AKLAKL-BNEBNE-SYD. (total 3537 miles) SYD-MEL (Can forgo this leg) 3975 miles.

I wasn't able to price this online.
