Presume KUW is meant to be Kuwait (IATA airport code is KWI)?
SYD lounge is nice but a long way from check in. If a/c gets a gate in the other pier, it is a long walk from the lounge to gate.
BNE is much like the SYD lounge, but additionally has an exit direct to the airbridge (stairs to drop down to it though). Great views from one side of the lounge.
AKL & MEL similar to SYD but without the views.
IIRC, the CHC lounge used by EK is Manaia Lounge, which is a contract lounge and very poor.
