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 (west of Penneshaw) on Kangaroo Island.[2] 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.
Discovery and exploration
Backstairs Passage was named by Matthew Flinders on 7 April 1802 whilst he and his crew on HMS Investigator were exploring and mapping the coastline of South Australia. Flinders noted that this body of water is separate from Investigator Strait and that "it forms a private entrance, as it were, to the two gulphs; and I named it Back-stairs Passage."[3]
