Sydney (pronounced sɪdni) is the largest city in Australia, with a metropolitan area population of approximately 4.34 million (2008 estimate). It is the state capital of New South Wales, and was the site of the first British colony in Australia. Situated on an inlet of the Tasman Sea, Sydney is built on low hills surrounding Port Jackson. It was established in 1788 at Sydney Cove by Arthur Phillip, admiral of the First Fleet from Britain.  A resident of the city is referred to colloquially as a Sydneysider.
