In the past I've gotten Qantas credit on AA as quickly as AA credit, but it's coming up on two weeks since my return flight now - more than that for the outbound leg - and nada for either. I'm just waiting for the 15-day minimum since the return flight to request credit for both via AA's Web form (which lets you request missing credit for any oneWorld airline flight). When I've done this in the past for a random glitch in an AA flight it's worked well.
