You guys ought to be less judgmental on 457 crews. There are many Oz pilots operating out of Europe that were embraced openly...sadly, this doesn't appear to be the case in Oz..xenophobia possibly? I guess it goes all the way to poor Labour Govt mandates that include visa entry for Brits, FIRB for UK residents to buy property and incredibly strict work visa protocols to boot. maybe you should be welcoming Afghan and Sudanese pilots with similar bias??
