In 1979, for instance, the Liberals won 55 percent of the two-party vote–the first time in 20 years that the non-Labor side in South Australia had won a majority of the two-party vote while also winning the most seats. However, they only won 25 seats—a bare majority of two—mainly due to winning only 13 seats in Adelaide. That narrow majority was reduced even further to 24 seats after the Liberal victory in Dunstan's old seat was overturned, and Labor won the ensuing by-election. Thus, despite having won by a margin large enough for a landslide victory in the rest of Australia, the Liberals only governed on a knife-edge.
