I have about 90k miles towards lifetime D+ with OZ, but given how much I fly, it's pretty much a non-issue. I can't seem to decide if I want to switch over to QF or stay with *A given the network in Australia. I have PriorityPass for now for lounge access but that's pretty much useless in Australia and the US.

I'm normally willing to take extra connections or pay extra (within reason) to fly on my favored carriers though. I'd like to upgrade every now and then but OZ doesn't even fly to MEL which is a bit of a concern (and *A upgrades require a Y fare, which at that point you might as well buy discount business).
