Proportional:
A voting system based on multi-member (6) electorates in which each successful candidate must reach a quota. The proportion of seats won by each party is approximately equal to its proportion of the popular vote.
Aim of it is to achieve a close relationship between the overall percentage of votes cast for a party (or independents) and the percentage of seats they win in parliament
Often termed “consensus systems” because they are less likely to result in single party control of the parliament.
Used in the Australian Senate or “upper house”
Uses a single transferrable vote at a smaller value so all required members can reach quota.
Surplus / Number of votes for candidate = Transfer value
(Number of formal ballot papers / (Number of senators to be elected + 1)) + 1 = Senate quota

Preferential:
A voting system where candidates must indicate their order of preference for the candidates listed on the ballot. The successful candidates must secure an absolute majority after preferences (primary votes) or have an absolute majority after preferences had been distributed. In a distribution of preferences the candidate with the fewest primary votes is eliminated and their preferences are distributed among the remaining candidates. This process continues until one candidate secures an absolute majority. This system is used for single member electorates.
