malapportionment

This post is a detailed look at Western Australia’s zonal electoral system ahead of a major review of how the Legislative Council is elected.

The malapportionment that applied to lower house boundaries was abolished with the introduction of one-vote one-value electoral boundaries at the 2008 election.

But malapportionment remains for the Legislative Council, and was in fact made worse by changes to region representation in 2008.

The bias in the electoral system against Perth has drifted out from 2.80-to-1 when the current system was adopted in 1989, to 3.07-to-1 in 2021.

But this hides another developing bias, an increased weighting against voters in South West Region. Where in 1989 average enrolment per MLC in the three non-metropolitan regions was equal, by the 2021 election, average enrolment in Agricultural Region and Mining and Pastoral Region had blown out to a ratio of 2.81-to-1 against voters in South West Region.

Western Australia’s current electoral regions defined by land usage rather than population is unsustainable given demographic trends.

The McGowan government has appointed a Ministerial Expert Committee chaired by QC and former WA Governor Malcolm McCusker to examine reform options for the Legislative Council. The existing malapportionment of the Legislative Council’s electoral system is one amongst several issues it will be addressing. (You can find details of the Committee here)

In this post I set out in detail the problems with the current malapportionment. In future posts I’ll return to other issues such as whether Western Australia should follow the Commonwealth, New South Wales and South Australia by abolishing group voting tickets for elections to the upper house.
