I'm by know means an expert but my guess is that it is very unlikely that you could get the whoel thing sorted out in Oz, even if it was with a multinational I don't think they could do it that way. On the postive most of the big firms pay towards travel costs- this is usually a train fare from 100 miles away rather than half the world but its still worth investigating. I know that if you have an MBA from a top business school our government rolls out the red carpet for you. Out of interest why do you want to move over here?-just new experiences etc, the £ goes along way etc. I do love my country and everything but I imagine quality of life in Sydney is higher, kiss goodbye to the sun until global warming kicks in. Of course there are also loads of good reasons to come here too.
