Can you explain how a senator is elected in Australia?<|im_end|>
<|im_start|>assistant
Sure! In Australia, the Senate is one of the two houses of the federal parliament, and senators are elected using a proportional representation system. Here's how it works:

1. Each state and territory in Australia is represented by a number of senators. There are 12 senators from each state and two from each territory, making a total of 76 senators in the Australian Senate.
2. Senators are elected for a term of six years, with half of the senators up for election every three years.
3. To be eligible to run for the Senate, a person must be an Australian citizen, at least 18 years old, and not disqualified under the Constitution or the Commonwealth Electoral Act.
4. Voters in each state and territory cast a vote for a political party or an individual candidate. They can either vote above the line, which means they are voting for a party, or below the line, which means they are voting for individual candidates.
5. If a voter votes above the line, they must number at least six boxes in order of preference. If they vote below the line, they must number at least 12 boxes in order of preference.
6. Once the votes are counted, the Australian Electoral Commission (AEC) uses a complex method called the Hare-Clark system to allocate the seats. This involves a process of redistributing the votes of the lowest-polling candidates until the desired number of seats is reached.
7. In order to be elected to the Senate, a candidate must receive a quota of votes, which is calculated based on the total number of formal votes cast and the number of seats to be filled.<|im_end|>

Who is eligible to cast a vote in Australia and are Australians living abroad able to vote for a senator?<|im_end|>
<|im_start|>assistant
Every Australian citizen who is aged 18 years or more can vote in a federal election if validly enrolled and not disqualified from voting. You will be validly enrolled if you are on the electoral roll at your current address (where you have lived for a month or more).

If you are an Australian citizen living overseas, you can still vote in federal elections if you have been outside Australia for less than three years. However, if you have been living overseas for more than three years, you will need to re-enrol.

I hope that helps! Let me know if there’s anything else I can help with.<|im_end|>

Does this system have any problems or loopholes that would make the result not fully reflect the cadidates' popularity?<|im_end|>

The Single Transferable Vote (STV) system used in Australian Senate elections aims to achieve proportional representation, but it can still have some issues and limitations:

1. Preference deals and group voting tickets: When voting 'above the line', voters can assign their preferences to parties or groups, who then determine the order in which candidates receive these preferences through group voting tickets. This can lead to preference deals between parties, which may not accurately reflect the voters' intentions. However, the 2016 reforms to the Australian Senate voting system have made it harder for minor parties to "game" the system through these deals.

2. Exhausted votes: In the vote counting and preference distribution process, a ballot can become "exhausted" if all the candidates a voter ranked have been either elected or eliminated, and the voter has not ranked any other candidates. Exhausted votes do not contribute to the election of any further candidates, potentially leading to some votes not being reflected in the final results.

3. Micro-party candidates and "preference harvesting": In some cases, micro-parties with a low primary vote can win Senate seats by benefiting from preference deals or preference harvesting, which can result in candidates being elected with a small percentage of first preference votes. This can be seen as a distortion of the voters' will, as it may not truly represent the popularity of the candidate.

4. Complexity and voter understanding: The STV system can be complex for voters, particularly when it comes to preference distribution and the effect of ranking candidates 'above the line' or 'below the line'. This complexity may lead to some voters unintentionally ranking candidates or parties that they do not truly support.

5. Underrepresentation of territories: The Australian Capital Territory (ACT) and the Northern Territory have fewer senators than the six states, leading to a potential underrepresentation of these territories in the Senate.

Despite these issues, the STV system in Australia provides a relatively fair representation of the voters' preferences. The system aims to ensure that the Senate composition reflects the diversity of political views in the country, and the 2016 reforms have helped to address some of the system's shortcomings.<|im_end|>
