1993 South Australian state election

The campaign was dominated by the issue of the collapse of the State Bank of South Australia in 1991. The State Bank's deposits were legally underwritten by the Government of South Australia, putting South Australia into billions of dollars of debt. Labor premier John Bannon had resigned over the issue in 1992, being replaced by Lynn Arnold just over a year before the election. The Liberals also changed leaders in 1992, switching from Dale Baker to Dean Brown. Following the Labor leadership change and by early 1993, Newspoll had recorded a total rise of 13 percent in the Labor primary vote.^[1] However, the gains did not last. A warning sign of things to come came with the March 1993 federal election, which saw two of Labor's longest-held seats in South Australia, Hindmarsh and Grey, fall to the Liberals. Hindmarsh had been in Labor hands without interruption since 1919, while Grey had been in Labor hands for all but one term since 1943.

The Liberals under Dean Brown went into the election as unbackable favourites, and swept the 11-year Labor government from power in a massive landslide. They won 37 of 47 seats (78.7 percent of the available seats, a majority of 14) in the South Australian House of Assembly from a 15-seat swing − in terms of seat count and percentage of seats won, the largest majority government in the state's history. By comparison, Sir Thomas Playford never governed with more than 23 seats in a 39-seat legislature during his record 27 years as Premier, and Don Dunstan never governed with more than 27 seats in a 47-seat legislature.

The Liberals won 60.9 percent of the two-party vote, the largest two-party preferred vote in South Australian state history (dating back to the first statewide two-party calculations from 1944). Labor fell to just 39.1 percent of the two-party vote from a two-party swing of 8.9 percent—at the time, the largest two-party swing in South Australian state history (second only to the 9.4 percent swing at the following 1997 election, and still the largest that resulted in a change of government. The 15-seat swing is still the largest in South Australian state history.

Adelaide, which had been Labor's power base in the state for decades, swung over dramatically to support the Liberals. Labor lost seats in several parts of Adelaide where it had not been seriously threatened in memory, and was cut down to only nine seats in the capital. Additionally, Labor suffered what proved to be permanent swings in much of country South Australia; it was cut down to only one seat outside of Adelaide, the Whyalla-based seat of Giles.

The stratospheric records for seat count and percentage of seats in the House led to predictions of a generation of Liberal government. However, the Liberal gains were short lived. Factional stoushes between the moderate and conservative wings of the Liberal Party led to Brown's factional rival, John Olsen, successfully challenging Brown for the Liberal leadership in 1996. In turn, the Liberals were reduced to a minority government as a result of the 1997 election, following another record two-party swing in the other direction of 9.5 percent.

A 1994 Torrens by-election saw Labor take the seat from the Liberals. The 1994 Elizabeth by-election and 1994 Taylor by-election saw Labor retain both seats.
