What cannot be booked without a stopover is QF2 LHR-DXB and QF2 DXB-SYD ( and same rule with QF1, QF9 and QF10 )
maybe my post was slightly ambiguous. You can indeed change from 1 flight number to another in Dubai, but if wanting to travel on the same flight the whole way, it must be booked as a single segment
