Australia is a very immigrant friendly country. There are many immigrants from many countries and the saying in Australia is, once you've come down there, it doesn't matter where you're originally from. Your an Ausi. This great attitude helps people integrate into Australian society with little trouble and can make the move to Australia much more pleasant.
I once met someone who immigrated to Australia from the former Yugoslavia and he said he was accepted into Australia with open arms.
From an economical standpoint there are many opportunities in Australia and the living standard is quite high in general.
Take Care.
