Aboriginals & dingo's are migrants to this country too, from Asia.
My father is Italian too, and he had lots of friends who used to rubbish Australia, and use to tell them to go home, if they didn't like it. My father was grateful to escape the war, and the remnants thereof.
I have many friends who aren't from here, Sri Lankans, Europeans, etc etc, and they all want to live this way of life, in general. Some do their own thing at home, which is their right, but they don't feel the need to push it on everyone else. They are happy with Australia being Australia.
