Step 1: Understanding Australia's voting system.
Australia uses the alternative voting method (also known as preferential voting) for elections to the House of Representatives. Voters rank candidates in order of preference, and if no candidate receives an absolute majority, the candidate with the fewest votes is eliminated and their votes are redistributed based on preferences, until a winner emerges.
Step 2: Analysis of options.
- (1) Alternative voting method: This is correct. Australia uses preferential voting in the House of Representatives elections.
- (2) Hare system: The Hare system is a proportional representation system used in some elections but not in Australia’s House of Representatives.
- (3) Condorcet method: This is a voting system used for ranked voting but not used in Australia’s House of Representatives elections.
- (4) Second ballot system: This is used in some elections but not in Australia for the House of Representatives.
Step 3: Conclusion.
The correct answer is (1) Alternative voting method.
