Nepean Bay is a bay located on the north-east coast of Kangaroo Island in the Australian state of South Australia about 130 kilometres (81 miles) south-south-west of Adelaide. It was named by the British navigator, Matthew Flinders, after Sir Evan Nepean on 21 March 1802.
Nepean Bay lies between Point Marsden and Kangaroo Head on the north-east coast of Kangaroo Island facing into Investigator Strait. Nepean Bay itself includes the following coastal inlets from west to east - Bay of Shoals, Western Cove and Eastern Cove. Eastern Cove itself includes an inlet consisting of a channel known as American River and a lagoon system known as Pelican Lagoon. [3]
The Bay of Shoals is a body of water which is located immediately north of the settlement of Kingscote and whose mouth is located between Cape Rouge in the north and Beatrice Point in the south over a distance of about 5 kilometres (3.1 mi). The bay has a maximum charted depth of 2.7 metres (8 ft 10 in). Its mouth is bounded by a spit known as 'The Spit' which extends from Cape Rouge to within 0.5 nautical miles (0.93 km; 0.58 mi) of Beatrice Point, includes the islets of Busby and Beatrice and is reported as being exposed during local tides, i.e. ‘drying.’ Access for watercraft into the bay is via a natural channel at its southern end near Beatrice Point. [3] [4] [2]
Kingscote Harbour is the sheltered water between Bay of Shoals and Western Cove. The harbour is sheltered by the Beatrice Islets, and it faces the northern part of the town of Kingscote. [5]
Western Cove is a body of water whose mouth is located between Beare Point in the west and Morrison Point in the east separated by a distance of about 8 nautical miles (15 km; 9.2 mi). The cove has a maximum depth of about 10 metres (33 ft) at its mouth. Its shoreline is described as (distances in nautical miles): [3] [2] [6]
The S(outh) shore, between Morrison Point and a red cliffy point about 3 miles W, is high and rocky. A range of wooded hills along the S(outh) shore falls gradually to the W(est). Red cliffs extend about 1.5 miles W(est) from the red cliffy point, and from there to the head of the cove is a continuous sandy beach. The land at the head of the cove is low and swampy and continues so to Beare Point…
Eastern Cove is the body of water whose mouth is located between Morrison Point in the west and Kangaroo Head in the east separated by a distance of about 6 nautical miles (11 km; 6.9 mi). The cove has a maximum depth of 14 metres (46 ft) at its mouth. Its shoreline is described as (distances in nautical miles): [3] [2] [6]
The shore of Eastern Cove, between Kangaroo Head and American Beach, 2.5 miles S(outh), is rugged and rocky. Between the SW end of American Beach and Rocky Point, it consists of alternate beaches and low, rocky points. A sandy beach forms the S(outh) shore between Rocky Point and Strawbridge Point, 2.75 miles WNW. The S(outh) side of the cove is low with wooded hills at the back.
Eastern Cove includes Ballast Head Harbor on the western side near Ballast Head. [7]
Matthew Flinders named Nepean Bay after Sir Evan Nepean, First Secretary to the Admiralty, on 21 March 1802. [8]
Settlements on its shores include Kingscote, Brownlow KI and Nepean Bay on the shores of Western Cove, and American River, Baudin Beach and Island Beach on the shores of Eastern Cove. [9]

It is currently located within the Flinders Chase National Park.
The Kangaroo Island Council is a local government area in South Australia that covers the entirety of Kangaroo Island, 13 km off the coast of the mainland.

Vivonne Bay is a bay in the Australian state of South Australia located on the south coast of Kangaroo Island about 61 kilometres (38 mi) from Kingscote, the island's main town, and which was named by the members of Baudin expedition to Australia who visited the bay in January 1803. In a survey of 10,000 beaches by Professor Andrew Short, director of Sydney University's marine studies centre, the beach at Vivonne Bay was adjudged as one of the best in Australia.
D'Estrees Bay is a bay in the Australian state of South Australia located on the southern coast of Kangaroo Island about 39 kilometres south of Kingscote, the Island's principal centre.
The Backstairs Passage is a strait in South Australia lying between Fleurieu Peninsula on the Australian mainland and Dudley Peninsula on the eastern end of Kangaroo Island. The western edge of the passage is a line from Cape Jervis on Fleurieu Peninsula to Kangaroo Head on Kangaroo Island. The Pages, a group of islets, lie in the eastern entrance to the strait. About 14 km wide at its narrowest, it was formed by the rising sea around 13,000 years ago, at the end of the Pleistocene era, when it submerged the land connecting what is now Kangaroo Island with the Fleurieu Peninsula. Backstairs Passage was named by Matthew Flinders whilst he and his crew on HMS Investigator were exploring and mapping the coastline of South Australia in 1802.
Stokes Bay is a bay in South Australia on the northern coast of Kangaroo Island located about 38 kilometres (24 mi) west of the town of Kingscote. It is described as being the largest of a number of coves located along the coast between Cape Dutton about 3 nautical miles (5.6 km) to the west and Cape Cassini about 7 nautical miles (13 km) to the east. The source of the bay's name is reported as taking its names from "supposedly takes its name from the first mate of the Hartley which arrived in South Australia in October 1837" and is not to be confused with a Henry Stokes (c.1808-1898), a sealer who lived on Kangaroo Island prior to 1836 or a John Stokes who arrived on the island in 1817 and who is reported as residing at Stokes Bay.
