Or you could purchase a Qantas Club membership for about US$300 that will get you into Qantas Clubs (of course), Admirals Clubs, BA Executive Clubs, and though it's not official, in the past they've also let me into Finnair and Iberia Lounges (the only others I've tried). Well worth the money. If you can stretch it, a life membership is fantastic value at about US$2000 (I think, without checking). Only problem with the life membership is that I don't need now I am OW Saphire !
