The election resulted in a hung parliament, with the Labor and Liberal parties on 17 seats each (out of 35). The balance of power was held by Kevin Lyons, a former Liberal who had quit the party in 1966 after a dispute over preselection and formed the Centre Party. Lyons approached Bethune with an offer for a coalition government with himself as Deputy Premier. Bethune agreed, allowing him to form government by one seat—thus consigning Labor to opposition for the first time in 35 years.
The Liberal-Centre coalition lasted for one term, with Lyons dissolving the partnership in 1972. The resulting instability triggered an election, which was easily won by Eric Reece and the Labor Party.
