I know they overnight in Tarawa at the moment.
Theres usually pilots up in townsville on overnights from memory.
You might get the occasional Canberra overnight with the honiara trips, used to get regular overnights on Norfolk Island. Every now and then (not sure if they will do it again), but overnights in Port Moresby and Cairns. Also every now and then a drw overnight.
Also from time to time, they fly up to places like BKK all stops - with overnights in DPS, KUL.
As its charter you really could end up anywhere.
Not a pilot and dont work there anymore, so cant help you as to whether they are recruiting. I do hear its not the best pay, but the pilots there I found were great guys and the crews 99.9% of the time had a good time. Oh, and its about 90% female hosties - which you may or may not like...
