Since I'm such a big Air NZ fanboi I don't fly Qantas/Jetstar very often. I have a single unused voucher here for Qantas club access that will get you into the Qantas lounge before a Qantas or Jetstar flight (obviously no lounge access domestically in NZ so it's international only)
Since I'm such a generous person and hate to see things go to waste the first person to reply to this can have it for free.. I won't even charge you for postage. This voucher expires at the end of April so you'll need to be flying before then.
