"Simple fact is now in Australia, 4 million Australian passport holders (many old enough to be voters) were born overseas and they are never going to vote for anyone other than a left wing Labour government...."

You are making a lot of assumptions here.

If people "born overseas" will always vote Labor, Australia would have had many more years of Labor government than has been the case, as this country is a nation of migrants.
