The Sydney Central Business District is the main commercial centre of Sydney, the state capital of New South Wales and the most populous city in Australia. The Sydney CBD is to a large degree coterminous with Sydney's city centre, or Sydney City, and the two terms are used interchangeably. The CBD or city centre is often referred to simply as "Town" or "the City". The Sydney city centre extends southwards for about 3 km from Sydney Cove, the point of first European settlement in which the Sydney region was initially established. Due to its pivotal role in Australia's early history, it is one of the oldest established areas in the country.
Geographically, its north–south axis runs from Circular Quay in the north to Central railway station in the south. Its east–west axis runs from a chain of parkland that includes Hyde Park, The Domain, Royal Botanic Gardens and Farm Cove on Sydney Harbour in the east; to Darling Harbour and the Western Distributor in the west. At the 2016 Australian Census, the City recorded a population of 17,252.
The Sydney City is Australia's main financial and economic centre, as well as a leading hub of economic activity for the Asia-Pacific region.
