Voters will mark their ballots in order of preference, ranking their top three favourite candidates. An individual must reach 50 per cent of the total to be declared elected; in each round of counting where a candidate has not yet reached that target, the person with the fewest votes is dropped from the ballot and their second or third choice preferences reallocated to the remaining candidates, with this process repeating until a candidate has reached 50 per cent.
