If you can depart from YVR, the following itinerary can be flown in J as a distance-based oneworld award for 150K AA miles:

Yvr-hkg-per-syd-dfw-sea

You would also have the opportunity to add an intra-Australian side trip to the award without exceeding the 25,000-flown-mile maximum on the 150K award.

Routing via LHR would push you into the 190K redemption level, even without the intra-Australian side trips.
