BA shares a lounge with Qantas here. The Club lounge is very shabby with lack of proper snacks and too few loo facilities. The loo is still used illegally by smokers ! Often there is insufficient seating. The First section of the lounge isnt much better. There ar 3 BA 747’s leaving for LHR within an hour or so of each other plus Qantas own flights so VERY busy !
The Virgin and Cathay Lounges are so much better.
My advice is dont use the lounge.
