Sydney is the state capital of New South Wales and the most populous city in Australia and Oceania. Located on Australia’s east coast, the metropolis surrounds the world’s largest natural harbour, and sprawls towards the Blue Mountains to the west.
The city has transformed from a colonial outpost into a major global cultural and economic centre. The population of Sydney at the time of the 2011 census was 4.39 million, 1.5 million of which were born overseas, representing many different nationalities and making Sydney one of the most multicultural cities in the world. There are more than 250 different languages spoken in Sydney and about one-third of residents speak a language other than English at home.
