'''Guichen Bay''', ({{IPAc-en|local|ˈ|g|iː|ʃ|ən}} {{respell|GHEE|shən}}, [[French language|French]]: Baie de Guichen) is a [[bay]] located on the south-east coast of the Australian state of [[South Australia]] about {{convert|115|km|abbr=off}} northwest of the regional city of [[Mount Gambier, South Australia|Mount Gambier]] and about {{convert|270|km|abbr=off}} south-southeast of the state capital of [[Adelaide city centre|Adelaide]]. It was named in 1802 by the [[Baudin expedition to Australia|Baudin expedition of 1800-03]] after [[Luc Urbain de Bouëxic, comte de Guichen]]. The town of [[Robe, South Australia|Robe]] is located at the southern end of the bay.

Guichen Bay lies between Cape Thomas at its northern extremity and Cape Dombey at its southern extremity on the south-east coast of South Australia. The east side of the bay which runs for a distance of about {{convert|6|nmi|km mi}} to the south of Cape Thomas is formed by a sandy beach known as Long Beach. The bay’s south shore consists of ‘rocky points and sandy bays’ with ‘drying rocks extend a short distance offshore’. Within the bay, the water depth ranges from {{convert|9.1|m|abbr=on}} to {{convert|11 |m|abbr=on}} over a large part of the bay.<ref>{{cite enroute|175|2017|229}}</ref> A rocky point known as Boatswain Point projects south for a distance of about {{convert|0.75|nmi|km mi}} to the east southeast of Cape Thomas while at the south end of the bay, there is a rocky point known as Robe Point.<ref name=chart5>DMH, 1985, chart 5</ref><ref name=BIAp181>BIA, 2005, page 181</ref>
A number of [[navigation aid]]s are located around Cape Dombey at the bay’s south end. These consist of a lighthouse known as the Robe Lighthouse on Cape Dombey, a flashing light located near Commodore Point on the ocean coastline to the immediate south of Cape Dombey, and two lights within the bay - a light marking the end of the breakwater at the entrance of the Lake Butler marina in Robe and a flashing light near Robe Point. Prior to the erection of the Robe Lighthouse in 1972, the sole navigational aid available for navigating in Robe was a [[Daymark]] in the form of an obelisk painted with red and white bands which is known as the Robe Obelisk.<ref name=BIAp181/><ref>{{cite web|title= The Robe Lighthouse|url= http://www.lighthouses.org.au/lights/SA/Robe/Robe.htm|publisher=Lighthouses of Australia Inc|access-date=27 October 2014}}</ref><ref name=marina>{{cite web|title= Lake Butler Marina|url=http://www.council.robe.sa.gov.au/page.aspx?u=302|publisher=District Council of Robe|access-date=27 October 2014}}</ref>
==History== The [[Bungandidj people]] were living in the Robe region prior to the arrival of Europeans.
The bay was first charted in 1802 by [[Nicolas Baudin|Baudin]] and [[François Péron|Péron]] of the [[Baudin expedition to Australia|Baudin expedition]]. Baudin named the bay Ances des Albatross, but this was revised after his death, in [[Louis de Freycinet|Freycinet]]'s publication, to Guichen Bay to honour French war hero [[Luc Urbain de Bouëxic, comte de Guichen]].<ref>{{cite web|title=Property Location Browser (search for 'Guichen Bay')|url=http://maps.sa.gov.au/plb/|publisher=Department of Transport Planning and Infrastructure|access-date=27 October 2014|archive-date=12 October 2016|archive-url=https://web.archive.org/web/20161012010923/http://maps.sa.gov.au/plb/|url-status=dead}}</ref>
In the 1830s, Bungandidj woman "Black Maggie" was the first indigenous inhabitant encountered by European men, probably whalers, sealers or sailors visiting the area several years before the [[British colonisation of South Australia|Province of South Australia]] was proclaimed.<ref>{{Cite web|url=https://www.robe.sa.gov.au/webdata/resources/files/Robes_History.pdf|title=Robes History}}</ref>
==Ports and other settlements== Robe is the sole [[human settlement|settlement]] and port in Guichen Bay. Its infrastructure consists of a jetty and a marina complete with a protective breakwater.<ref name=BIAp181/><ref name=marina/>
==Protected areas== The following [[protected areas]] respectively include and adjoin the bay’s extent: the [[Upper South East Marine Park]] and the [[Guichen Bay Conservation Park]].<ref>{{cite web|title=MARINE PARK 18, Upper South East|url=http://www.environment.sa.gov.au/files/9c61898b-f387-4cd4-ab6e-a117012727a9/mp-gen-map-18a-uppersoutheast.pdf|publisher=Department of Environment, Water and Natural Resources|access-date=27 October 2014}}</ref><ref name=NPWS>NPWS, 1994, page 4</ref>
