How will you earn the ff miles/avios/points?
Getting an award ticket can be hard, especially at peak times (Christmas, Easter, Olympics, etc). Note that BA (and QF/EK) have award cash surcharges, so always check the cash price. For Aussie, domestic fares can be cheap so do not concentrate on getting to Brisbane BNE/ Gold Coast OOL direct from UK.
Flights UK/Eu to Australia is very competitive, with many airlines. The middle east & Asian/Chinese airline often have lowish fares on sale.
