My visit to the Q Club is generally a 10 minute sit in a lounge with a glass of average shiraz.
While I do live in the Eastern Suburbs, if I happened to be in the west and going to Melbourne I think this would be a good idea. Crack a few St Hallets and stick them in the Bankstown departure lounge and you've basically improved on the overcrowded Qantas Club.
Points for giving it a go - but as mentioned, it will no doubt go the way of every other startup
