They all fresh off the boat and def not born here - which is fine.
The Aussie born ones are def a different breed altogether.
Only one which was close to Aussie born which I encountered was Jasmine at 227 Broadway a couple years back - I cant be sure she was born here, but she certainly had that type of feel.

The others who claimed they were born here over the years were just doing it for more money and marketing purposes - but once you met them in person, you can smell the FOB on them right away.
