New Zealand Lounge!
When we're transiting through SYD on our way back to SFO we come early to join the throngs at the Koru Lounge. Food is better than United C and we really enjoy the hot dogs. Annie (the Rock Star-see Hemispheres Feb) is also there, to help with any last minute SNAFUs.
I am not sure about the arrivals: going on to MEL we could use the lounge. Transferring to Qantas or Virgin we did not....there is a thread somewhere about finding an Arrivals type lounge. What class are you flying in Australia? That may help w access if you are in Business or First.
