Port Jackson Totally Explained

Port Jackson, containing Sydney Harbour, is the natural harbour of Sydney, Australia. It is known for its beauty, and in particular, as the location of the Sydney Opera House and Sydney Harbour Bridge.

History

The land around Port Jackson was occupied at the time of European discovery and colonisation by various tribes including the Gadigal, Cammeraygal, Eora and Wanegal peoples. The Gadigal people are said to have occupied the land stretching along the south side of Port Jackson from what is now South Head, in an arc west through to Petersham. The Cammeraygal lived on the northern side of the harbour. The area along the southern banks of the Parramatta River, west of Petersham to Rose Hill, was reported to belong to the Wanegal. The Eora people lived on the southern side of the harbour, close to where the First Fleet settled.
The harbour's discovery by Europeans is credited to Lt James Cook in 1770, although he didn't enter it. Cook named the harbour after Sir George Jackson, Judge Advocate of the Fleet at the time; he noted in his log that "there appears to be a good anchorage". Captain Arthur Phillip established the first colony in Australia at Sydney Cove inside Port Jackson in 1788 which was to become the city of Sydney. In his first dispatch from the colony back to England letter noted that "...we had the satisfaction of finding the finest harbour in the world, in which a thousand sail of the line may ride in the most perfect security..."(External Link

Geography

Geologically, Port Jackson is a drowned river valley, or ria. It is 19 km long with an area of 55 km². The estuary's volume at high tide is 562,000 megalitres. The perimeter of the estuary is 317 kilometres.
According to the Geographical Names Board of NSW, Port Jackson is "a harbour which comprises all the waters within an imaginary line joining North Head and South Head. Within this harbour lies North Harbour, Middle Harbour and Sydney Harbour." These three harbours extend from the single entrance (known as Sydney Heads (North and South Heads)). North Harbour is the shortest, and is really just a large bay extending to Manly. Middle Harbour extends to the north-west. It is bridged at The Spit and Roseville. Its headwaters lie in Garigal National Park. The longest arm, Sydney Harbour, extends west as far as Balmain, where it's fed by the estuaries of the Parramatta and Lane Cove rivers. Port Jackson is bridged by the Sydney Harbour Bridge and the ANZAC Bridge (formerly known as the Glebe Island Bridge). A tunnel, the Sydney Harbour Tunnel passes underneath the Harbour, to the east of the bridge, and in 2005 it was proposed that a third harbour crossing, this time a railway line, be constructed to the west of the bridge. The harbour is heavily embayed. The bays on the south side tend to be wide and rounded, whereas those on the north side are generally narrow inlets. Sydney's major central business district begins at Circular Quay, a small bay on the south side that has, over time, had its semi-circle reclaimed by land to the point where it's a rectangular quay. The northern side of the harbour is mainly used for residential purposes.
The waterways of Port Jackson are managed by the New South Wales Maritime Authority.

Islands

There are several islands within the harbour, including Shark Island, Clark Island, Fort Denison, Goat Island, Cockatoo Island, Spectacle Island, Snapper Island and Rodd Island. Some other former islands, including Bennelong Island, Garden Island and Berry Island, have subsequently been linked to the shore by land reclamation.

Sydney Harbour Ferries

Sydney Ferries is a state-owned corporation of the New South Wales Government providing commuter and tourist passenger ferry services in Sydney Harbour.

Sydney Harbour as a unit of measurement

In Australia the size of many bodies of water are referenced back to the size of Sydney Harbour, that's a body of water x is y times the size of the Sydney Harbour. The unit of measure would be s. For example: Lake Argyle, the Ord river dam and Australia's second largest artificial lake, is variously described as "18 times that of Sydney Harbour" or 18 sydharbs (External Link

), "8-13 times the size the volume of Sydney Harbour." (External Link

), and "nine times the size of Sydney Harbour" (External Link

). Warragamba Dam in New South Wales and Sydney's major water supply is described as being "4 times the size of Sydney Harbour" (External Link

). Lake Eucumbene, one of the major dams in the Snowy Mountains Scheme, "holds nine times the volume of Sydney Harbour" (External Link

), or perhaps thirteen times (External Link

). The comparison isn't confined to dams. Jervis Bay in New South Wales is "at least 6 times bigger in volume (and 4 times bigger in area) than Sydney Harbour" (External Link

); and Boston Bay in South Australia, on which Port Lincoln is located, is three and a half times larger than Sydney Harbour.
