Immigration has dramatically changed Australia, mainly for the better. I don’t think any country has done it as well. If I could be more precise, I think Australia has benefited most from refugees. Whilst the first generation of refugees may often lack skills and education, they more than make up for it in enterprise, courage and risk-taking. That enterprise and high aspirations are often expressed through their children. Refugees are by definition risk-takers who will abandon all for a new life. They select themselves much better than a migration officer can ever select them.
