Nothing has changed much; the economic elites are still pinning their hopes, indeed their lives on the immigration economy created in the post-world War II period. This is not a real nation, for it explicitly aims to dissolve the identity created by Anglo-Australia prior to the war, and given a few more ecological/biological shocks, it should all fall apart, beautifully:

“Australia's dependence on immigration to grow the economy is about to be sorely tested. One of the secret ingredients to Australia's unparalleled run of economic growth since the country's last recession has been strong population growth. While local mums have played their part in swelling the number of locals, the heavy lifting has been done by people from nations such as China, India, Britain, New Zealand and the Philippines who have decided to call Australia home. Over the past decade, the nation's permanent population has grown by 3.7 million to more than 25 million. Of that increase, 60 per cent was due to net migration. That extra 2.2 million people have been an economic powerhouse, requiring homes, cars, food and every day goods and services while also contributing fresh skills to the jobs market. But it has come at a price, particularly in Sydney and Melbourne. Be it via higher house prices or over-crowded schools, all levels of government have struggled to keep up with the demands of a growing population while reaping the economic benefits of that population.”
