"What are Australias “immigration policies” if you show up you get to stay?"
Australia will intake 190,000 immigrants with Australia's current population being 26,473,055.
That's about 717 immigrants per 100,000 people annually.
Whereas in the US, they would intake about a million immigrants, with its 2022 population being at 333,287,557.
That's about 300 immigrants per 100,000 people annually.
This is just the legal immigrants alone.
In July 31st 2023, Australia had 1079 people in their immigration detention facilities.
Yet in the US, 2.76 million migrants illegally crossed the border.
Calculating the rate of illegal immigrants per 100,000 people, Australia has way less illegal immigrants than the US, yet the US has over 800 illegal immigrants per 100,000 people.
The US has more illegal immigrants than Australia per 100,000 people, yet Australia intakes more legal immigrants than the US. Reason? Because Australia would have been more accommodating of immigrants than the US from many different policies I don't want to have to look into today, but I would later.
