Which city in Australia has the most immigrants?

Toronto's international population shows that it is an important foothold for immigration to Canada. 49% of the city's population was born outside Canada, which makes Toronto one of the most ethnically diverse cities in the world. At present, Toronto is listed as one of the most livable cities in the world by many economic think tanks because of its low crime rate, clean environment, high living standard and tolerance of multiculturalism.
