This just all seems quite strange to me? One minute they decide they need crew for these bases, the next they aren't required? Something doesn't seem right, and I'm sure they're up to something - what I don't know. Surely they need to put crew into those bases somehow? Only other thing I can think of is they're just transferring more and more of the flying to SYD base, thus removing of pairings/overnights/need for crew in BNE/MEL??
