We were in the SQ FC lounge in Sydney in Feb 2014 on the way back to BKK on TG, and it is quite small, and except for the ~6 seats by the windows overlooking the tarmac it seemed semi-claustrophobic to me. Nothing to write home about. One of the staff was monopolizing one of the window seats to chat on her cell phone which was annoying. Veuve was on-hand, and they prepared a decent, though forgettable light meal for us. The food on the buffet was shrink-wrapped so it seemed we were there in between busy times. No issues at all getting in. The door to the lounge slides open very Star Trek-like.
