SIN: I liked the new QF First Lounge very much (open since approx. Nov 19), you get introduced at the entrance, they have a nice a la carte dining area, attentive service. Yes, it is not First Class only, it is open to OW Emerald as well, but i had the impression they knew is F-class guest (BA/QF F as well of course) and who is "just" Emerald.
