No, it really was a paid upgrade. It is international - MEL-HKG. Really, honestly and truly, even after clicking '+ More Flight Info' nothing shows about my class of flight - either in words or code letters. I know people who use this succesfuly will think I am doing something wrong or not loking properly, but I really am looking and checking. Checkmytrip worked perfectly - so it is confirmed there. I also now have the itinerary with confirmation via email - so I am happy with that. It still does not show my class of booking in any way at all when I log on to the Qantas site - honest :>) This what it shows:
Status: Confirmed
Flight Duration: 8h 51m

That's all there is after the normal flight details of time etc.
