Goolwa is a historic river port on the Murray River near the Murray Mouth in South Australia, and joined by a bridge to Hindmarsh Island. The name "Goolwa" means "elbow" in Ngarrindjeri, the local Aboriginal language, and the area was known as "The Elbow" to the early settlers.
Goolwa is approximately 100 km south of Adelaide, and is the seat of the Alexandrina Council. It is in the state electoral district of Hammond and the federal Division of Mayo. At the 2011 census, the state suburb of Goolwa (excluding Goolwa Beach, Goolwa North and Goolwa South) had a population of 2201. The ABS no longer publishes separate urban population estimates for Goolwa alone. At June 2015 the estimated urban population for Goolwa together with nearby Victor Harbor was 25,877.
