The Senate (Upper House) Electoral System

Since the reforms to the Senate in 2016, individuals must vote either 1- 6 above the line or 1 - 12 below. This is in contrast to the pre-2016 system which encouraged voters to simply vote 1 above the line for their preferred party and allow the party to then decide where it goes; what's known as a group voting ticket. The current system used by the Senate is referred to as a partial preferential system and is strikingly different to the House of Reps. The Senate elects 12 representatives from each state and from these states 76 Senators, approximately half of the House of Reps, are elected by reaching a quota of the overall percentage of formal (valid) votes. 

Whereas the Lower House system is designed to try and ensure a single party governs with clear lines of accountability, Senators are elected through a system of proportional representation. Seats are distributed according to the proportion of the vote gained by a party, creating a greater diversity of views which act as a check on the power of the ruling party in the Lower House (the Executive). In short, a party with 10% of the vote would have 10% of the seats on offer. Unlike NSW's Legislative Assembly exhausted votes do not affect the numbers needed to fill a quota and are therefore less important. However, counting of the votes in the Senate is significantly more complex than in the House of Reps. 

Whereas the House of Reps uses a small ballot and has few parties running in each seat, the Senate ballot is often caricatured as a "tablecloth" due to its size and number of competing parties. Since the changes in 2016 voting above the line (ATV) requires voters to number candidates from 1 to 6 in order of preference. This is in contrast to the previous system of Group Voting Tickets, in which individuals could simply vote 1 above the line and allow their preferences to be determined according to the will of the Party. Below the line (BTV) voting requires individuals number at least 12 candidates in order of their preference. Previously it required filling every single box. Simply put, to vote in the Senate you need to remember either six above or twelve below.

 Without going into unnecessary detail, after the first round of counting candidates who received a quota (14% of the vote at regular elections, 7.7% during double dissolutions) are elected and their surplus votes - those accrued by a candidate that are in addition to their quota - are transferred to the next on their party ticket at a reduced value. If there are no votes left to count due to exhausted votes the final seats are allocated as they would be in a First Past the Post system, going to individuals with the most votes until all seats are filled. Antony Green, Australia's preeminent psephologist (electoral expert) provides a more in-depth analysis, explaining the maths and formulas more in-depth for those so inclined.

Institutional Role of the Senate

Given the Senate's institutional role as a "house of review" acting as a check on executive power, this arrangement can arguably be said to have struck a fair balance, keeping in mind no system is without flaws. The system of checks and balances in Australian Parliament is, briefly, that: the executive (government) makes the law, the Senate, comprised of a broader cross-section of the Australian population due to their electoral system of proportional representation, reviews the law and the judiciary (the courts) interpret the law when need be. Dispersing power in this manner is a defining characteristic of liberal democracies. 

Due to the unequal populations of each state and the exact same level of political influence each wields in the Senate, the democratic principle of one person one vote is utterly perverted. This is not without good reason as it goes to the heart of the tension between democracy and liberalism found in every liberal democratic state. As always, the efficacy of the Senate in functioning as a house of review is dependent on its composition and the values of the individual making the assessment. Historically, the system has operated extremely well. With a double majority - majorities in both houses - occurring only a few times. 

Political Philosophy of the Senate

In terms of political philosophy, the Lower House emphasises democratic elements, such as strong government, ministerial responsibility and clear lines of accountability, while the Senate emphasises liberal elements (liberal in this sense refers to protection of the individual, not the economic liberalism championed by the liberal party and to a lesser extent Labor and the Greens). This is why the Senate abandons the democratic notion of one person one vote: it functions primarily as a liberal, not democratic institution. Furthermore, it was arguably necessary for the early colonies to come together in federation. This is highly problematic for those who argue for proportional representation as being more democratic than other systems as it depends on which aspect of contemporary democracies one is referring to.

Also in clear support of the notion above is the fact the Senate utterly perverts the fundamental democratic notion of one person one vote by giving states with large discrepancies in population relative to others equal levels of political power in the Senate. In this context the Senate can never be more democratic than the House of Representatives.

At this point it should be clear the complexity of our system makes any discussion of it extremely difficult to have in any sort of meaningful sense. Confusions arise almost immediately without definitions and it is extremely difficult to classify a specific type of democracy as inherently superior to another - an argument repeated countless times - as there are always trade offs between these elements which go straight to the core of our personal values.
