The election saw the Liberal and Country League opposition win the same number of seats in the House of Assembly as the incumbent Australian Labor Party government, despite the fact that Labor won 53.2 percent of the two-party-preferred vote and the LCL only 46.8. However the LCL assumed office with the support of the long-serving independent member for Ridley, Tom Stott. Stott, a good friend of former Premier Playford, and with no liking for the ALP, agreed to support the LCL and was elected as Speaker of the Assembly.
Hall had served as leader of the opposition for two years before becoming Premier. Young and handsome, he was also the first Australian state premier to sport sideburns. Indeed, the 1968 election, fought between Hall and his opponent Don Dunstan, was described by the Democratic Labor Party as the battle of "the matinee idols".
Hall found himself in a politically unacceptable position as a result of the obvious unfairness of the election result, and decided to institute electoral reforms to end the malapportionment of the Playmander. At the 1968 election there were only 13 metropolitan electoral districts containing 0.7 million people, whereas there were 26 rural districts containing 0.4 million people. The reforms included increasing the number of lower house seats from 39 to 47. In the 2006 election there were 35 metropolitan districts representing 1.1 million people and 12 rural districts representing 0.4 million people. Further reforms would be implemented after the 1975 election in which Labor retained government despite a two-party-preferred vote of 49.2 percent, as well as the 1989 election where Labor retained government despite a two-party-preferred vote of 48.1 percent. South Australian is the only state to deliberately draw electoral boundaries based on the two-party preferred vote. It was legislated after 1989 that the Electoral Commission of South Australia should redraw boundaries after each election with the objective that the party which receives over 50 percent of the two-party-preferred vote at the forthcoming election will form the government.
Eventually Hall and Stott fell out over the proposed Chowilla Dam. Stott wanted the dam built in his electorate while Hall thought its construction was not justified. Constituent anger forced Stott to vote against the Hall government, leading to an early election - the 1970 South Australian state election, which would be fought on much fairer electoral boundaries.
