The Australian Labor Party is affiliated with Australian Concil of Trade Unions (the ACTU) and was originally a democratic socialist party. As such the Australian Labor Party has traditionally been a left wing party, but under the Hawke and Keating governments of the eighties and early nineties has drifted towards the centre. They are also somewhat culturally progressive.
While a liberal party by name, the Liberal Party of Australia emphasises economic liberty at the expense of cultural liberty. This makes them right wing. The Liberal Party even has a conservative tendency which is only accented by its long-standing coalition with the National Party, making them somewhat low on the social progressiveness scale.
Although the National Party holds some principles that would be considered socialist, almost all of these relate to protection of rural communities and primary production. The fact that they value individual acheivement over that of collective acheivement is enough to make them right of centre. They are also very conservative morally, making them low on the social progressiveness scale.
Economically moderate they are in the centre of the left right scale, but highly socially progressive with support for reconciliation, immigrants cultural identity and homosexual rights.
Although it is set up as a corporation rather than a traditional party, One Nation is neither really left or right. As a political movement it is a group of conservative Australians who feel disaffected by market rationalism. Probably even lower than the Nationals on the social progressiveness scale.
One shortcoming of this test is that it does not rate levels of environmentalism. If it did the Australian Grees (along with the Democrats) would be advocates of ecological sustainability, while the other parties would be much more for economic development. The Greens are also left-of-centre on economic issues and progressive socially.
