The dagos wogs or whatever you wish to call them came here in an orderly fashion. Apart from the ten pound Poms all other Europeans paid their own way here aboard ships that were used exclusively for immigrants. I was on one such ship. The population then was less than 12 million, now it's over 21 million and this country cannot sustain a population much above say a max of 30 million. I suggest you read a book written by that great Aussie who truly cares for this country, Dick Smith about what can happen with overpopulation.
Rubbish on so many levels I can't even be bothered to detail them all. Great Aussie Dick Smith? What a laugh. Almost singlehandedly destroyed the Australian electronics industry, and he acknowledges this.
And do you realise that you are spouting deep, dark green philosophy? Tim Flannery, a great mate of Bob Brown, advocates a population of 12 million. Do you agree? Perhaps you might (greenie) because that happened to be the population when you arrived. How will this be achieved?
Have you looked at demographic projections for Australia without immigration? Have you looked at skill shortages hampering our economy? Do you want immigration to cease, regardless of the consequences?
