Prior to the passing of the Constitution Act Further Amendment Act 1881, the Legislative Council had been 18 members elected by people from across the entire Province.
Transitional arrangements meant that members were only to be elected from the new districts as the terms of the existing members expired.
[1] From 1891, all members of the Council were elected by districts.
The Constitution Act Amendment Act 1901 reduced the size of the parliament, but Central District was the only one to continue to elect six members, from a slightly larger area including some of the Adelaide Hills.
[3] The act provided that the sitting members should decide amongst themselves which three represented each of the two new districts.
