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.

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.
