It is much easier to move (and to immigrate) in Canada than Australia, however. Entrepreneurial spirit may be similar, but immigration laws are very different (and, although less critical, the distance from large markets).

I was discussing (and with the proviso that my knowledge was superficial at best) immigration policy - which seems comparable. Googling around shows me that Australia has a large foreign born population (24%), and a points based system similar to Canada's.
