My OP was inspired by an interview with Antony Green on the ABC. He has also posted an article on ABC Online on 29 August expressing similar ideas to improve the system. (Look for the article "Senate voting threatens more than our eyesight".) I'll post a couple of paragraphs below and comment on them.
Quote:My concern is that the farce of the 2013 Senate election may produce the wrong sort of change, where the existing players get together and simply make it impossible for the little parties to grow or get elected by introducing threshold quotas.
(Without checking, I think a threshold quota is a minimum percentage of the vote that a party or candidate can receive to be eligible to be elected. In the NZ parliament which has proportional representation, the threshold is four percent.)
Quote:The better alternative is to do what NSW did after the 1999 debacle, to abolish between-ticket preferences, but allow voters to express their own preferences for parties above the line on the ballot paper. Preferences are moved back into the hands of voters where they belong, and parties that campaign for votes with how-to-vote material can try to influence preferences, but parties that don't campaign for votes lose control of their preferences.
Green is suggesting that we abolish tickets completely, rather than using the #1 ticket as the default as I suggested. If optional preferential voting is also implemented below the line, a similar system is needed above the line, so that the number of candidates numbered above the line is at least equal to the number of vacancies. On the other hand, it would explode the below-the-line candidate count.
Do we really need below-the-line candidate lists at all?
We could make a compelling case to abolish below-the-line voting. We should consider taking a look at other voting systems around the world. Many countries with a bicameral system have the equivalent of a Senate with proportional representation. In many of those systems, the voters vote for parties and not individual candidates. Germany has this kind of system for the proportional representation - vote for the party, and if the party meets a threshold their candidates get elected.
(The German and New Zealand parliaments are unicameral with local seats and list seats, such that the parliament overall has proportional representation. Governments by coalitions are the norm because it is rare for one party to exceed 50%.)
Quote:As a minimum, the Victorian Legislative Council system should be copied. Voters are only required to give as many preferences below the line as there are vacancies, five in the Victorian case. This is much fairer than the endless lists of preferences required in the Senate.
I suggested exactly the same idea here (see OP). It is a natural extension of optional preferential voting.
