The boundaries for the locality were first created in 1994 for the long established local name; initially, they only comprised the section within the City of Port Augusta, with the Mount Remarkable section being added in 1997. The name was derived from the Hundred of Winninowie, which in turn stemmed from a word of Aboriginal origin. However, the modern Winninowie locality lies entirely within the Hundred of Davenport, with its eponymous hundred lying directly to its south.[1]
