I agree that fairs fair. There are plenty of Oz pilots in the UK and if you have residency rights why not give it a go.
My point is that there are plenty of out of work pilots in Australia. These guys are being chosen I guess because they have command experience on type. Surely there are enough pilots within
VB who are suitable for command. Or if they need FO's I'm sure there is definately no shortage of candidiates in Australia.
