I wouldn't class QF lounges as better than the DJ ones though, which whilst in AU is probably more relevent given that in USA , AA lounges are hardly anything to write home about

According to the DL site, DL lounge membership shows as providing for access to VA lounges

I think that there is a lot more chance of VA providing a status match to Platinum than there is of QF providing any status match which, if provided, would make VA a much better choice imo
