Sydney is the largest city in Australia and the state capital of New South Wales. Sydney is an international centre for commerce, arts, fashion, culture, entertainment, education and tourism.
Sydney has a metropolitan area population of approximately 4.34 million and an area of approximately 12,000 square kilometres. Sydney has a temperate climate with warm summers and cool winters, and rainfall spread throughout the year. Sydney's urban area is in a coastal basin, which is bordered by the Pacific Ocean to the East, the Blue Mountains to the West, the Hawkesbury River to the North and the Royal National Park to the South.
Sydney's central business district (CBD) extends southwards for about 3 kilometres from Sydney Cove to the area around Central station. The Sydney CBD is bounded on the east side by a chain of parkland, and the west by Darling Harbour, a tourist and nightlife precinct.
The City of Sydney itself covers a fairly small area comprising the central business district and its neighbouring inner-city suburbs. In addition, regional descriptions are used informally to conveniently describe larger sections of the urban area. These include Eastern Suburbs, Hills District, Inner West, Canterbury-Bankstown, Greater Western Sydney, Northern Beaches, Northern Suburbs, North Shore, St George, Southern Sydney, South-eastern Sydney, South-western Sydney, Sutherland Shire and Western Sydney.
