Who, living in Australia, would want to immigrate to US? Most of the people I know would be happy to go as far as Hawaii (for a holiday) but moving to US from Downunder.......hmm.......you would have to have a good bloody reason, especially given the possible outcome of the upcoming elections. As for the rest of the countries mapped on this viz, I totally understand.
The people who I've personally known that migrated from Aus to the US do so for very lucrative economic reasons (job in software development or Hollywood) or for love. I don't think anyone is going to move in either direction between the two countries in search of a significantly better life.
