Totness consists mainly of industrial zoned areas. It is commonly referred to as Mount Barker or Littlehampton but is actually a town of its own. There is no street sign indicating you are entering Totness. Its Windmill is the oldest surviving building in the Hahndorf - Mt Barker area.
It is about 2 kilometres (1.2 mi) from Mount Barker, and 1 kilometre (0.62 mi) from Littlehampton, but the towns have merged due to growth.
It is also home to the Totness Recreation Park.
Totness was first subdivided in the 1880s, without regard to its contours. Part of the movie 'Ned Kelly', starring Mick Jagger, was filmed on Totness Rd.
