This is a four year old thread.

Since the time of the OP's post, the following has happened:

Australian Airlines has pretty much disappeared (ie been brought back into the Qantas name completely, and is just an operating airline for Qantas now).
Jetstar has replaced Australian Airlines as the Qantas low cost international carrier.
Qantas now allows Qantas Club members who are flying on Jetstar access to the Qantas Club.

Qantas have changed things so that the original complaint wouldn't happen today (ie flying Jetstar and being denied access to a Qantas Club (branded) lounge).
