As pointed out , you would only get 3581 points and 3581 miles if you fly on the QF flight number.

if you book on the AA codeshare you will get 7161 miles and 7161 qpoints. Definately worth booking the AA flight numbers where you can. If you are flying from Europe down towards Asia on your trip, the WT+ supplement on BA is definately worth considering; a much more comfortable flight plus 110% miles ( rather than the likely 50% on QF or 25% on BA or zero on CX ) for a fee of AUD600 for either UK-Asia or BKK/SIN-SYD or AUD900 LHR-SYD
