The Alexandrina Council area is a growing rural and rural-residential area, with township and holiday areas. Alexandrina Council encompasses a total land area of just over 1,800 square kilometres.
The natural amenity of the region and its proximity to Adelaide act as significant drivers for growth. In recent years, population growth in Alexandrina has been well above the average for South Australia. The region has long been a destination for retirement migrants and other lifestylers, particularly the coastal towns in the southern part of the municipality. In common with most parts of regional Australia, Alexandrina loses young adults to Adelaide, other parts of Australia and overseas, who often move for employment, education or lifestyle reasons.
