Duncan is a locality in the Australian state of South Australia located on Kangaroo Island about 162km (101miles) south-west of the state capital of Adelaide and about 49km (30miles) west of the municipal seat of Kingscote.[1] [2]
Its boundaries were created in May 2002 for the “long established name” which was derived from the cadastral unit of the Hundred of Duncan. The Playford Highway forms the southern boundary of the locality.[1]
The principal land use in the locality is primary production with land on the western side of the locality located in a ‘water protection zone’ in order to manage the aquifer system existing within Duncan and adjoining localities.[7] [1]
Duncan is located within the federal division of Mayo, the state electoral district of Mawson and the local government area of the Kangaroo Island Council.[5] [4] [1]
