Attack on Sydney Harbour

Port Jackson or Sydney Harbour is the ria or natural harbour of Sydney, New South Wales, Australia. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. 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.

Garden Island ferry wharf is located on the southern side of Sydney Harbour. It serves the Royal Australian Navy's Heritage Centre, Garden Island.

The Royal Australian Navy Heritage Centre is the maritime museum of the Royal Australian Navy. The centre opened on 4 October 2005 and is located within the Public Access Area on the northern end of the Garden Island naval base in Sydney. The need for such a facility was first recognised in 1922, by Vice Admiral Sir William Creswell who suggested the building of a museum to permanently display the Australian Navy's already rich and unique heritage. Since then, there have been several attempts to establish an international-standard naval museum. The origins of the RANHC date from 2001, when the then Chief of the Navy commissioned a Naval Heritage Management Study to examine in detail how the RAN's past might best be used to support the present Navy's goals. One of the most important recommendations was the creation of a facility for the public display of the Naval Heritage Collection (NHC). Once approval for funding was received, a RANHC Project Board was formed and the project began on 24 May 2004. The NHC contains more than 250,000 individual items, and the mission of the RANHC is to display those objects of museum standard to the public, and through these displays capture something of the Australian naval experience.

The Garden Island Tunnel System, also known as Garden Island tunnels, Garden Island Tunnel Complex and Potts Point Tunnels, is a former tunnel warfare system in Garden Island, Sydney, Australia. Used in World War II by the Royal Australian Navy in 1941, the tunnels were dug from sandstone beneath Potts Point after the Japanese attacked Pearl Harbor, to shelter the men working at the naval base from air raids. Some of the tunnels feature names such as Petticoat Lane (named after London's landmark), North-West Passage and Lambeth Walk.The tunnel system featured a power station, a command centre, offices and air raid shelters. Today, the tunnels and chambers are used for electrical wiring and communications.

Colonist was a general cargo and passenger schooner built in 1861 at Dumbarton Scotland by Denny & Rankine. It spent nearly 30 years plying the Western Pacific-based out of Sydney. It wrecked and later re-floated on the remote Elizabeth Reef 550 km from New South Wales, as well as being involved in the gold rushes. Its master was murdered before it was finally involved in a collision in Sydney Harbour, in which it was sunk.

HMAS Kuttabul is a Royal Australian Navy (RAN) base located in Potts Point in Sydney, New South Wales, Australia. Kuttabul provides administrative, training, logistics and accommodation support to naval personnel assigned to the various facilities that form Fleet Base East, the main operational navy base on the east coast of Australia. A part of Fleet Base East itself, Kuttabul occupies several buildings in the Sydney suburb of Potts Point and in the immediately adjacent Garden Island dockyard. It also supports navy personnel posted to other locations throughout the greater Sydney region.The base is named for the steam ferry HMAS Kuttabul that was sunk while docked at Garden Island during a Japanese midget submarine attack on Sydney Harbour in 1942.

Fort Denison Light, also known as Pinchgut Light, is an active lighthouse located on top of a Martello Tower at Fort Denison, a former penal site and defensive facility occupying a small island in Sydney Harbour, New South Wales, Australia.

Fort Denison, part of the Sydney Harbour National Park, is a protected national park that is a heritage-listed former penal site and defensive facility occupying a small island located north-east of the Royal Botanic Gardens and approximately 1 kilometre (0.62 mi) east of the Opera House in Sydney Harbour, New South Wales, Australia. The island is also known as Mattewanye/Muddawahnyuh, in the Eora language (Sydney Language), and as Pinchgut Island. The site contains time gun, navigational aids and tide gauge facilities. Correctional and military facilities were designed by George Barney and built from 1840 to 1862 by William Randle.

Robertson Point Light, also known as Cremorne Point Light, is an active lighthouse in Cremorne Point, a suburb on the lower North Shore of Sydney, New South Wales, Australia. It is the sibling of Bradleys Head Light. The lighthouse is mounted on a rock and connected to shore by a footbridge.

The Fleet Base East is a Royal Australian Navy (RAN) major fleet base that comprises several naval establishments and facilities clustered around Sydney Harbour, centred on HMAS Kuttabul. The Fleet Base East extends beyond the borders of Kuttabul and includes the commercially-operated dockyard at Garden Island, and adjacent wharf facilities at nearby Woolloomooloo, east of the Sydney central business district in New South Wales, Australia. Fleet Base East is one of two major facilities of the RAN, the other facility being the Fleet Base West. The fleet operates in the Pacific Ocean. Confusingly, naval personnel often use the term Fleet Base East to mean the naval wharves at Garden Island where ships assigned to the Fleet Base usually berth but the official designation includes several other bases and facilities as well.
