Southend is a settlement in South Australia, on the southern shore of Rivoli Bay. From 1842, the settlement was called Grey Town, after Governor of South Australia George Grey, and was later renamed Grey. It was given its current name of Southend in 1971. At the 2006 census, Southend had a population of 560.
The Southend Caravan Park is in very close proximity to the white beaches of Rivoli Bay. The Bluff, less than a five-minute drive from Southend, is a popular scenic destination for locals and tourists. The Rivoli Bay Sailing Club sails catamarans and monohulls, and is located at the end of Leake Street. The club sails from October to April on weekends.
