Simpson is a small town in the Western District of Victoria Australia. The town is in a dairying region and lies about halfway between Colac and the coastal fishing resort of Port Campbell. Most of the town is located in the Corangamite Shire, but a small, forested section lies in the Shire of Colac Otway. Simpson is 20 kilometres (12 mi) south of Cobden. At the 2016 census, Simpson had a population of 569.
The town is named after Les Simpson, the first chairman of the Soldier Settlement Commission. Prior to the formation of the Soldier Settlement Commission in 1946, the large bush land tract known as the Heytesbury Forest was under consideration as a possible settlement area.
Simpson is part of one of the most productive dairying centres in Australia. Dairying has become a major activity in the area and a significant contributor to the State’s dairying industry. The region consists of dissected plains exposing a range of land types with different topography, lithology and soils. This results in a range of responses to land use and climate.
The town today services the needs of 400 plus farms, through Education, Health and Produce.
