On November 24^th 2007, Australia elected its House of Representatives with instant runoff voting (IRV), as it has for more than eight decades. After four straight election defeats, the Labor Party won a landslide majority of seats. Under IRV, Labor's initial 44% of first choices turned into a clear majority after considering the choices of supporters of third party candidates with too little support to win seats. The Green Party's 7.79% share of the national vote largely went to Labor in House races; that share earned several senate seats elected by proportional voting. Due in large part to compulsory voting, turnout was 94.77%; Australians rank near the top of national comparisons of voter satisfaction with their government.
