Port Jackson

Port Jackson, commonly known as Sydney Harbour, is a natural harbour on the east coast of Australia, around which the city of Sydney is situated. It consists of the waters of Sydney Harbour, Middle Harbour, North Harbour, and the Lane Cove and Parramatta rivers. The harbour is an inlet of the Tasman Sea, which in turn is part of the South Pacific Ocean. It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge. As the location of the first permanent European settlement on the Australian mainland, Port Jackson has played a key role in the history of Sydney, as well as its social and economic development. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g., Robert Brown's Prodromus Florae Novae Hollandiae et Insulae Van Diemen, described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's Eve celebrations. The harbour is also the starting point of the Sydney to Hobart Yacht Race. The waterways of Port Jackson are managed by Transport for NSW. Sydney Harbour National Park protects a number of islands and foreshore areas, swimming spots, bushwalking tracks and picnic areas. The harbour is a global hotspot for marine and estuarine diversity.
