Parliament House, on the corner of North Terrace and King William Road in the Adelaide city centre, is the seat of the Parliament of South Australia. It was built to replace the adjacent and overcrowded Parliament House, now referred to as "Old Parliament House". Due to financial constraints, the current Parliament House was constructed in stages over 65 years from 1874 to 1939.
The 47-seat House of Assembly (lower house) consists of 24 Labor, 21 Liberal and 2 independents, Geoff Brock and Martin Hamilton-Smith.
Following the 2014 election, the lower house consisted of 23 Labor, 22 Liberal and 2 independents, Geoff Brock and Bob Such. Martin Hamilton-Smith became an independent shortly after the election, reducing the Liberals to 21 seats. Both Hamilton-Smith and fellow independent Geoff Brock are in cabinet and provide confidence and supply while retaining the right to vote on conscience. Labor went from minority to majority government when Nat Cook won the 2014 Fisher by-election which was triggered by the death of Bob Such.
The 22-seat Legislative Council (upper house) consists of 7 Labor, 8 Liberal, 2 Green, 2 Family First, 1 Dignity for Disability and 2 independents, John Darley and Bernard Finnigan.
