| Voting system |
Proportional:
Single-transferable-vote. Under this system, each elector indicates an order of preference among all the candidates of the constituency; he/she may alternatively indicate support for the registered order of preference of a party or group of candidates. Once the number of first preference votes obtained by each candidate has been recorded, an electoral quota for the state or territory is determined by dividing the total number of votes by one more than the number of seats to be filled and increasing by one the result so arrived at. Any candidate who receives the established quota of votes is declared elected. Senate candidates receiving votes in excess of the quota have their surplus votes distributed (at a discount), according to their electors' ranking of preferences. If all the positions are not filled by candidates obtaining quotas by this means, then the next preferences of the voters for the least successful candidates are distributed, until all vacancies are filled by candidates obtaining quotas. The final result is a constituency with several candidates elected, each representing a proportion or quota of the total vote.
Vacancies are filled by selection of a person of the same political party by a joint sitting of the houses of parliament of the state or territory concerned.
Voting is compulsory. Unwarranted abstention is punishable by fine. |
