I think Australia has to be a country which has the 'Welcome' sign out.
A familiar question for Australians is how much we are a product of our circumstances, and how much we are what we have made ourselves to be. In truth, by the act of migration the country was made: by that voluntary act and by the emigrants' ambitions it was built.
Well, Australians should speak for the national interests of Australia, and whatever role former Australian prime ministers may have, one of the things you do is speak frankly about the country as you see the country's best interests, you know?
