Singleton is an outer suburb of Perth, the capital city of Western Australia, located entirely within the City of Rockingham local government area. It is the southernmost suburb of the Perth metropolitan area and is actually closer to the regional city Mandurah than either the Perth central business district or Rockingham. The area is under development near the school, Singleton Primary, and near the main oval, Laurie Stanford Reserve. There is a petrol service station, a small shopping centre, and a school.
