I am using one from BNE-SYD next week on the way back from the BNE bash. Seems like a waste, but it expired a few days ago (30NOV) so I had to use it on *something*, and of all my flights planned - SYD-CBR-SYD return, SYD-BNE mid afternoon, BNE-SYD late evening, SYD-MEL mid afternoon, MEL-SYD mid-morning - the late evening BNE-SYD seemed to offer the best value.
