Australian House of Representatives elections use full-preferential voting: voters number every box. If no candidate has more than half the first-preference votes, the candidate with the fewest is excluded and their ballots pass to each voter’s next preference, repeating until someone has more than half. Practical lesson: rank the candidate you most want to win first and the one you most want to lose last.
