In my last post I published an analysis of the new state electoral boundaries for Western Australia. The boundaries were drawn on one-vote one-value principles, a signature reform introduced by the Gallop government in 2005, and one that helped deliver Labor a record majority at the 2017 election. (see this post)
The unfinished business of the 2005 reforms was the Legislative Council. One-vote one-value only applied to the Legislative Assembly, the state’s lower house. It undid a two-to-one weighting against Perth that had applied since 1989, but left in place a three-to-one weighting in the Legislative Council, the state’s upper house.
In 2005, Labor and the Greens could not agree on a reform model for the Legislative Council. As part of the deal for lower house reform, the Greens wanted the existing six regions retained, but with six member per region instead of the existing five and seven member regions. This left in place the three-to-one weight against Perth, but added a new bias to the system by increasing the weight of votes in Agricultural Region and Mining and Pastoral Region at the expense of South West Region. At the 2017 election, a vote in Mining and Pastoral Region carried seven times the weight of a vote in Perth, a weighting that can only increase at future elections.
