Australia held a Parliamentary election on September 7. All of the seats in the House, and slightly over half the seats in the Senate, were up. Although not all results are final, Australia’s minor parties did better than they usually do.
The House uses single-member districts and ranked-choice voting (instant-runoff voting). The tentative results are Liberal-National Coalition 86, Labor 57, Green 1, Australian Party 1, independent 1, four seats not yet determined.
The Senate uses proportional representation. The new Senate will apparently be: Liberal-National Coalition 33, Labor 25, Green 10, Palmer United 2, and one seat each for these parties: Liberal Democratic 1, Xenophon Group 1, Family First 1, Democratic Labor 1, Motoring Enthusiast 1, Sports Party 1. No party has a majority in the Senate. For more about the election, see the wikipedia story.
According to this story, 21% of the voters cast a ballot for a party other than one of the two major parties.
This story explains that the Green Party victory in the House was unexpected, because the Liberal-National Coalition and Labor each recommended to their voters and supporters that the voter’s second choice vote be given to the other major party, not the Green.
This story, which is intriguing but not very clear (to me, anyway) talks about the Senate results and the small parties that each won a seat.
Julian Assange’s WikiLeaks Party did not win a Senate seat; see this article.
