European settlement dates from 1838, with the first township established in 1840 at Willunga. The Noarlunga township (now Old Noarlunga) was established in the same year, serving as a business centre for the region until the 1980s. Land was used mainly for grazing and farming, particularly wheat growing. Growth took place in the late 1800s, with subsequent towns such as Reynella and McLaren Vale developed around the wine industry. Land was also used for horticulture, orchards and quarrying, with the area remaining largely rural until significant development in the post-war years, spurred by the outward spread of Adelaide's growth. Rapid development took place between the 1950s and 1970s. Residential growth spread to the foothill areas of O'Halloran Hill, Happy Valley, Flagstaff Hill and Woodcroft in the 1980s and early 1990s. Growth has continued from the early 1990s, although at a slower rate, with the population of the City rising from about 127,000 in 1991 to over 156,000 in 2011. Much of the growth in the 1990s was in the suburbs of Aberfoyle Park, Seaford, Seaford Rise and Woodcroft. Growth from 2001 continued in the suburbs of Seaford and Seaford Rise, but was also significant in the suburbs of Aldinga Beach and Seaford Meadows.
