Members of the South Australian Legislative Council, 1975–1979

This is a list of members of the South Australian Legislative Council from 1975 to 1979.

This period operated under transitional arrangements following the rearrangement of the Council from a restricted-franchise house with ten provinces each electing two members, to a 22-member house elected to staggered terms on an open franchise, proportional representation model. Due in part to a constitutional requirement that those elected at the 1973 election serve six-year terms, the next Council election was in 1979 even though the next Assembly election was held in 1977.

¹ Liberal MLC Frank Potter died on 26 February 1978. Trevor Griffin was appointed to the resulting casual vacancy on 7 March 1978.
