Port Jackson

The first recorded European discovery of Sydney Harbour was by Lieutenant James Cook in 1770. Cook named the inlet after Sir George Jackson, one of the Lord Commissioners of the British Admiralty, and Judge Advocate of the Fleet.[4] As the Endeavour sailed past the entrance at Sydney Heads, Cook wrote in his journal "at noon we were...about 2 or 3 miles from the land and abrest of a bay or harbour within there appeared to be a safe anchorage which I called Port Jackson."

Eighteen years later, on 21 January 1788, after arriving at Botany Bay, Governor Arthur Phillip took a longboat and two cutters up the coast to sound the entrance and examine Cook's Port Jackson. Phillip first stayed over night at Camp Cove, then moved down the harbour, landing at Sydney Cove and then Manly Cove before returning to Botany Bay on the afternoon of 24 January. Phillip returned to Sydney Cove in HM Armed Tender Supply on 26 January 1788, where he established the first colony in Australia, later to become the city of Sydney. In his first dispatch from the colony back to England, Governor Phillip noted that:[5][6]

...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...

— Governor Arthur Phillip, 15 May 1788.

The Great White Fleet, the United States Navy battle fleet, arrived in Port Jackson in August 1908 by order of U.S. President Theodore Roosevelt. From 1938, seaplanes landed in Sydney Harbour on Rose Bay, making this Sydney's first international airport.

A Japanese Kō-hyōteki class midget submarine M-21 being raised from Taylor's Bay on 1 June 1942

In 1942, to protect Sydney Harbour from a submarine attack, the Sydney Harbour anti-submarine boom net was constructed. It spanned the harbour from Green (Laings) Point, Watsons Bay to the battery at Georges Head, on the other side of the harbour. On the night of 31 May 1942, three Japanese midget submarines entered the harbour, one of which became entangled in the western end of the boom net's central section. Unable to free their submarine, the crew detonated charges, killing themselves in the process. A second midget submarine came to grief in Taylor's Bay, the two crew committing suicide. The third submarine fired two torpedoes at USS Chicago (both missed) before leaving the harbour. In November 2006, this submarine was found off Sydney's Northern Beaches.[7]

The anti-submarine boom net was demolished soon after World War II, and all that remains are the foundations of the old boom net winch house, which can be viewed on Green (Laings) Point, Watsons Bay. Today, the Australian War Memorial has on display a composite of the two midget submarines salvaged from Sydney Harbour.[8][9] The conning tower of one of the midget submarines is on display at the RAN Heritage Centre, Garden Island, Sydney.[10]

Fort Denison is a former penal site and defensive facility occupying a small island located north-east of the Royal Botanic Gardens in Sydney Harbour.

There are fortifications at Sydney Heads and elsewhere, some of which are now heritage listed. The earliest date from the 1830s, and were designed to defend Sydney from seaborn attack or convict uprisings. There are four historical fortifications located between Taronga Zoo and Middle Head, Mosman, they are: the Middle Head Fortifications, the Georges Head Battery, the Lower Georges Heights Commanding Position and a small fort located on Bradleys Head, known as the Bradleys Head Fortification Complex. The forts were built from sandstone quarried on site and consist of various tunnels, underground rooms, open batteries and casemated batteries, shell rooms, gunpowder magazines, barracks and trenches.[11][12]

East to west, north side:

• North Head
• Dobroyd Head
• Middle Head
• Georges Head
• Bradleys Head
• Cremorne Point
• Kurraba Point

• Berry Island

East to west, south side

• South Head
• Point Piper
• Darling Point
• Potts Point
• Bennelong Point
• Dawes Point
• Millers Point
• Pyrmont
• Balmain

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, though their names often still contain the word "Island". Exposed at low tide is Sow and Pigs Reef, a well-known navigation obstacle near the main shipping lane.

• Tank Stream was a fresh water course emptying into Sydney Cove. Today it is little more than a storm water drain but originally it was the fresh water supply for the fledgling colony of New South Wales in the late 18th century. It originated from a swamp to the west of present-day Hyde Park and at high tide entered Sydney Cove at the intersection of Bridge and Pitt Streets.
• Middle Harbour is the northern arm of Port Jackson. It begins as a small creek (Middle Harbour Creek) at St Ives.[15] It joins the main waterway of Port Jackson between the two headlands, Middle Head and Grotto Point Reserve, adjacent to the Sydney Heads.
• Parramatta River is the western arm of Port Jackson. The river begins at confluence of Toongabbie Creek and Darling Mills Creek west of Parramatta and joins the main waterway of Port Jackson between Greenwich Point, Greenwich, and Robinsons Point, Birchgrove.[16]
• Lane Cove River rises near Thornleigh and flows generally south for about 15 kilometres (9.3 mi). Its catchment area is approximately 95.4 square kilometres (36.8 sq mi).
• Tarban Creek, a northern tributary of the Parramatta River, enters Port Jackson at Hunters Hill.
• Johnstons Creek is located in the inner-western suburbs of Glebe, Annandale, Forest Lodge and Stanmore. It rises in Stanmore and flows in a generally northward direction towards Rozelle Bay. The creek passes beneath the stands of the now demolished Harold Park Paceway prior to emptying into Rozelle Bay at Bicentennial Park Glebe. Orphan School Creek is a tributary of Johnstons Creek.
• Duck River is a perennial stream and southern tributary of the Parramatta River.

Port Jackson shrouded in bushfire smoke during Black Summer.

Port Jackson has a humid subtropical climate (Köppen: Cfa) with warm, somewhat humid summers and mild to cool winters, with moderate rainfall spread throughout the year. Due to its proximity to the open Tasman Sea, it is slightly cooler, wetter and breezier than Observatory Hill to the east. Port Jackson is also least affected by extreme heat due to the constant sea breezes, in addition to featuring the lowest maximum summer temperatures in the Sydney region, that average at just 24.4 °C (75.9 °F). Conversely, winter nights are among the warmest in Sydney, which rarely dip below 8.0 °C (46.4 °F), although fog can usually occur and may be disruptive.

Port Jackson's weather station is located within a lighthouse just south of Georges Head at Georges Heights in Mosman and is adjacent to the suburbs of Vauclause, Point Piper and Watsons Bay, which are on Port Jackson's east side towards the Pacific Ocean. Sydney Cove, a bay in Port Jackson's west side that includes Circular Quay, is more proximate to the Observatory Hill weather station, and therefore the climate data below does not apply to that vicinity.

Port Jackson is bridged from north to south by the Sydney Harbour Bridge, the Gladesville Bridge, the Ryde Bridge, and the Silverwater Bridge.

Other bridges spanning Port Jackson waterways are Pyrmont Bridge spanning Darling Harbour; the Anzac Bridge (formerly known as the Glebe Island Bridge), spanning Blackwattle Bay; the Iron Cove Bridge spanning Iron Cove; the Spit Bridge spanning Middle Harbour; the Roseville Bridge spanning Middle Harbour; the Tarban Creek Bridge spanning Tarban Creek.

The original Meadowbank Bridge carried two railway tracks, now reduced to pedestrian traffic only. The new Meadowbank Bridge carries two railway tracks with piers suitable for four tracks.

The is single track rail bridge on the Clyde to Carlingford railway line crosses the Parramatta River near Camellia.

• Mortlake Ferry

A weir at Queens Avenue, Parramatta separates the saltwater and tidal waters to the east from the freshwater and non-tidal waters to the west.

A road tunnel, the Sydney Harbour Tunnel passing underneath the Harbour to the east of the bridge was opened in August 1992.

In 2005, 2010 and in 2014 the NSW Government proposed a rail tunnel be constructed to the west of the Sydney Harbour Bridge. Construction of an extra pair of road tunnels to the west of the Sydney Harbour Bridge, as part of the Sydney Metro project, was approved in January 2017 while the Harbour tunnelling was completed in March 2020.[20] [21]

The Western Harbour Tunnel & Beaches Link is planned to offer another motor vehicle tunnel in 2026.

Carnival Spirit cruise ship in Sydney Cove in 2013

Permanent cruise ship terminals are located at the Overseas Passenger Terminal at Circular Quay, Sydney Cove and at the White Bay Cruise Terminal at White Bay. White Bay's evolution to a cruise terminal came with the closure of Darling Harbour terminal to make way for the Barangaroo development.[22]

White Bay and adjacent Glebe Island have been working ports since the mid-1800s, handling just about everything from timber and paper, coal, sugar and cement to cars and containers. The NSW Government identified both as vital to the City's economy and in March 2013 announced its commitment to maintaining both as working ports as it frees up neighbouring bays for public access. Glebe Island is Sydney's last remaining deepwater port able to supply the City's ongoing demand for dry bulk goods such as sugar, gypsum and cement.[22]

Most of Sydney's port infrastructure has moved south to Botany Bay since the construction of the first container terminals there in the late 1960s and early 1970s.
