 Australia 's electoral system uses preferential voting for all lower house elections with the exception of Tasmania and the ACT which , along with the Senate and most state upper houses , combine it with proportional representation in a system known as the single transferable vote . Voting is compulsory for all enrolled citizens 18 years and over in every jurisdiction , as is enrolment ( with the exception of South Australia ) . The party with majority support in the House of Representatives forms the government and its leader becomes Prime Minister . In cases where no party has majority support , the Governor @-@ General has the constitutional power to appoint the Prime Minister and , if necessary , dismiss one that has lost the confidence of Parliament .

 Under one person , one vote , each country 's number of votes is directly proportional to its population . This would be similar to how U.S. states are represented in the United States House of Representatives . In The Future of Sovereignty - Rethinking a Key Concept of International Relations , Hasenclever et al. sum up the advantages and disadvantages of this system : " In a strict meaning of democracy based on individuals as subjects , every person 's vote would have to have exactly the same weight . None of the known proposals , however , supports such a strict interpretation , because the inequality among the states ' voting powers would be extreme with only four countries - China , India , the United States and the former USSR - disposing of an absolute majority . " A way to resolve the disparity in population between countries would be to apportion representation to regions instead of nations . This would , for example , place Suriname and Brazil , the least and most populated South American countries , in a single South American voting bloc of approximately 400 million people , preserving the one person , one vote system while eliminating extreme disparities in population . This approach , however , is dependent upon elected officials being entrusted to represent said regions and not just their home countries , and could potentially leave some less populated countries with no representatives from their country if they are either outvoted by people in more populated countries in their assigned region or if the people in less populated countries vote in large numbers for candidates or political parties from other countries .

 Several proposals to abolish the Electoral College by constitutional amendment have been introduced in Congress over the decades . These efforts have , however , been hampered by the fact that a two @-@ thirds vote in both the House and Senate are required to send an amendment to the states , where ratification by three @-@ fourths of the State legislatures is required for it to become operative .

 In addition , it has been suggested that the GRC scheme merely provides an appearance of a united , multiracial Parliament . In fact , minority representatives are required to vote according to their party line ; they are not allowed to vote specifically in the interests of their racial groups . The multiracial element in Parliament has been artificially imposed by way of a racial quota to ensure that the minorities are represented .
