Full preferential

Full preferential vote counting is currently used to elect House of Assembly members in South Australia.

For instructions on how to complete the House of Assembly ballot paper see our page on ballot papers.

To win the election, a candidate must receive more than 50% of the formal votes. This is known as an absolute majority.

If a candidate receives more than 50% of the first preference votes, that candidate is elected.

Now, if no candidate has obtained more than 50% of votes a process of elimination begins. First, the candidate who has received the fewest first preference votes is excluded. The second preferences of the excluded candidate are allocated (shared out) to the remaining candidates. The totals for candidates remaining in the count are recalculated.

The process of elimination continues if there is still no candidate with an absolute majority of votes. This cycle of elimination and redistribution continues until one candidate receives an absolute majority of votes. Once a candidate reaches majority of votes they are elected to the House of Assembly.
