Australia doesn't do that. If you are an Australian resident sure, but America takes it the step further than even if you aren't a resident of the US you still get taxed on your foreign earnings.
For example, if you were born in the US to non-US parents who then take you back to their native country when you are say 1 when when you earn an income in that other country 17 years later you need to file a US tax return. Of course you can just not do so but that will be an issue if you ever decide to move to the US.
