The Perth Longhaul crew only fly to Asia. The destinations they slip in are SIN, HKG and NRT. They also do CGK shuttles from PER. The longest trip is 6 days (NRT).
A friend of mine who is shorthaul was looking into the new Shorthaul Base, with the hopes of transferring. The proposed patterns are only WA regional flying, plus DRW returns. No overnights were in the proposed patterns, and no flights to the eastern states. The CC website syas there are no plans to increase the size of the perth base from it's initial opening numbers.
Needless to say, after seeing that - she decided against transferring to Perth
Hope this helps.
