Investigator Strait is a body of water in South Australia lying between the Yorke Peninsula, on the Australian mainland, and Kangaroo Island. It was named by Matthew Flinders after his ship, HMS Investigator, on his voyage of 1801–1802. It is bordered by the Gulf St Vincent in the northeast.
The Investigator Group is an archipelago in South Australia that consists of Flinders Island and five island groups located off the western coast of the Eyre Peninsula.

Memory Cove is a bay located on the East coast of Jussieu Peninsula on Eyre Peninsula in South Australia approximately 15 kilometres (9.3 mi) South-East of Port Lincoln.
Jussieu Peninsula is a peninsula located at the south east end of Eyre Peninsula in South Australia. It is bounded by Proper Bay and Spalding Cove within the natural harbour known as Port Lincoln to the north, Spencer Gulf to the east and the Great Australian Bight to the south. While it was first explored and mapped by Matthew Flinders during February 1802, Flinders did not name it. In 1913, the name proposed by François Péron and Louis de Freycinet from Baudin's expedition when it visited later in 1802 was declared as the peninsula's official name by the Government of South Australia. Jussieu refers to the French botanist, Antoine Laurent de Jussieu. While parts of its surface have been cleared and used for agricultural purposes in the past, it is currently occupied by two protected areas: the Lincoln National Park and the Memory Cove Wilderness Protection Area.

While it is within the coastline first charted by Matthew Flinders on 9 February 1802, it is not named by Flinders possibly due to the coastline being obscured by a thick haze. Slade Point was named in 1908 after “the late Mr. W. E. Slade” who served as the Assistant Engineer of Harbours in the South Australian Government. The cape has adjoined the boundary of the Cape Blanche Conservation Park since 2012 while the waters adjoining its shoreline have been within a habitat protection zone in the West Coast Bays Marine Park also since 2012.
