At the time, the voting system in Queensland was based on contingency voting, which was similar to the modern optional preferential voting system. In electorates with 3 or more candidates, preferences were not distributed if a candidate received more than 50% of the primary vote.
If none received more than 50%, all except the top two candidates were eliminated from the count and their preferences distributed between the two leaders, with the one receiving the most votes declared the winner.
