The Macquarie Lighthouse, also known as South Head Upper Light, is the first, and is the longest serving, lighthouse site in Australia. It is located on Dunbar Head, on the Old South Head Road, Vaucluse in the Municipality of Woollahra local government area of New South Wales, Australia.

There has been a navigational aid in this vicinity since 1791 and a lighthouse near the present site since 1818. The current heritage-listed lighthouse was completed in 1883. The lighthouse and associated buildings were designed by James Barnet and built from 1881 to 1883.
Sepia apama, also known as the giant cuttlefish and Australian giant cuttlefish, is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in weight. Using cells known as chromatophores, the cuttlefish can put on spectacular displays, changing color in an instant. Sepia apama is native to temperate and subtropical waters of Australia, from Brisbane in Queensland to Shark Bay in Western Australia and Tasmania to the south. It occurs on rocky reefs, seagrass beds, and sand and mud seafloor to a depth of 100 metres. In 2009 the species was listed at Near Threatened on the IUCN Red List of Threatened Species due to an observed declining trend at that time.

It marks Green Cape on the northerly shore-hugging sailing course.
Port Bonython is the location of a deepwater port, gas fractionation plant and diesel storage facility west of Point Lowly in the Upper Spencer Gulf region of South Australia. It lies 16 km east-northeast of Whyalla, South Australia and approximately 370 km north-west of the State's capital city, Adelaide. The existing wharf is 2.4 kilometres long and is capable of berthing small Capesize ships with a maximum capacity of 110,000 tonnes. The wharf was established in 1982 and named after John Bonython, the founding chairman of Santos.

An oil spill at Port Bonython in 1992 resulted in loss of bird life and damage to mangrove habitats to the west and southwest of Port Pirie.

At the original location now stands a modern fiberglass tower.
Point Lowly is the tip of a small peninsula north north-east of Whyalla in the Upper Spencer Gulf region of South Australia. The wider peninsula is shared by a combination of defence, industrial, residential, recreational and tourism interests. Port Bonython lies immediately to the north-west and is marked for future industrial expansion, driven by anticipated growth in the State's mining industry. The icons of the peninsula are the historic Point Lowly Lighthouse and the mass breeding aggregation of giant Australian cuttlefish which occurs inshore each winter.
The Althorpe Islands are a group of islands in the Investigator Strait, off the south-western tip of Yorke Peninsula, South Australia. The group includes Althorpe Island and two rocky islets immediately to its west known as The Boobs. These are located 7.7 km south-southwest of Cape Spencer on the mainland. Closer inshore are Seal Island and Haystack Island, which together with Althorpe Island and The Boobs constitute the Althorpe Islands Conservation Park.

The two boundary beaches are accessible by vehicles from the Port Bonython Road while the central three are surrounded by salt and tidal flats and tidal creeks. False Bay's beaches are not patrolled but are rated among the state's least hazardous.

The Alternative Port Working Party is a community action group based in Whyalla, South Australia on the shore of northern Spencer Gulf. Its membership includes a number of retired engineers with experience in mining, shipping and bulk commodities handling and its chief spokesperson is Sid Wilson. Since its formation, the group has advocated for a 'best of both' scenario for the nearby Point Lowly peninsula; one which represents the interests of both the local economy and residential, recreational and tourist use of the peninsula. They believe that the chosen locations for proposed facilities in the Port Bonython and Point Lowly area present unacceptable compromises, and thus have recommended a number of alternatives.
Save Point Lowly is a community action group based in Whyalla, South Australia. The group was formed circa 2008 to present an alternative vision for the future of the Point Lowly area north-west of Whyalla and resist plans for heavy industrialization. The group aspired to raising the profile of the Point Lowly area, including the giant Australian cuttlefish aggregation, which the group believes is under threat from a number of industrial proposals including: a seawater desalination plant for BHP Billiton's Olympic Dam mine, a diesel distribution hub, a technical ammonium nitrate plant and an iron ore export facility. Collectively these development have been referred to by the Government of South Australia as the Port Bonython Minerals Precinct. The group's spokesperson and chairman is Andrew Melville-Smith who is a practising veterinarian and resident of Whyalla.
Fitzgerald Bay is a large bay located between Point Lowly and Backy Point in South Australia's upper Spencer Gulf. The bay's shoreline consists mostly of pebble beaches and sparse grey mangroves. In the 2000s the bay was used for the farming of yellowtail kingfish until their closure circa 2011 in response to high levels of fish mortality. Understanding of the environmental impacts of yellowtail kingfish farming is limited. As of 2021, fish farming has not returned to Fitzgerald Bay, but aquaculture zones remain in place, and Clean Seas is authorised to restock fish farms there. There are approximately forty shacks and coastal homes sparsely distributed along the fringe of Fitzgerald Bay whose interests are represented by the Cultana Jenkins Shackowners' Association.
