Wrong Hooroo. Just two days ago I flew QF 121 SYD to ZQN.
A Qantas 737-800 with VH registration and all-Australian crew led by Captain Andrew Simpson.
Apart from additional (Jetconnect) flights that were put on during the ski season, QF 121 and 122 are the real deal, and I hope it stays that way as I am a fairly frequent flyer on that route.
