Wild Horse Plains is a locality in South Australia on the eastern coastline of Gulf St Vincent about 69km (43miles) north-northwest of the Adelaide city centre.[4] Its name is attributed to Thomas Day, who found wild horses grazing within the locality around 1870.[5] Its boundaries, created in June 1997, include the town of Wild Horse Plains, established in 1881 on Port Wakefield Road, and the former Government Town of Lorne.[6] Port Lorne Road marks most of the northern boundary of Wild Horse Plains and is the access road to the former township of Lorne.[4]
Wild Horse Plains lies within the federal Division of Grey, the state electoral district of Narungga[2] and the local government area of the Adelaide Plains Council.[7] [3]
The post office opened in 1878, continued as a telephone exchange and closed in 1979. http://www.auspostalhistory.com/MOBI/articles/2080.php[8]
