Here's one some folks may be interested in:
April/May 2015 (various dates) out of YOW/YUL/YYZ to SYD "the long way" for $4,500+/- in J on AF/KLM/Skyteam.
Outbound routes you through either CDG/AMS with onward travel on Etihad through AUH.
Return allows you to add some QF/CX segments to the mix (through SIN or HKG onwards to CDG).
Good deal considering the fare routinely goes for 9k on AC. 18k flying blue miles each way.
