Final Two-Party Preferred result for 2021 Western Australian Election

Lower house results are now final for the 2021 Western Australian election, including the full distribution of preferences for all seats. The results reveal the extra-ordinary scale of Labor’s victory.

(The distribution of preferences for Legislative Council regions will take place later this week. I’ve provided commentary pending the release of the LC preference distributions at the page hosting my ABC Legislative Council calculators.)

Labor has won 53 of the 59 seats in the Legislative Assembly, up 13 on the 40 seats it held before the election. The Liberal Party’s representation in the lower house has collapsed from 13 seats to just two. In Parliament the opposition will now be led by National Party Leader Mia Davies, her party having emerged from the carnage with four seats, down two from the six it held before the election.

Labor has recorded 69.7% of the state-wide two-party preferred vote, a swing in it’s favour of 14.1%. That’s on top of the 12.8% swing that put Labor into office in 2017.

Of the 59 seats, 58 finished as two-party contests with the Greens finishing second in Fremantle. (Note: 31 March – That there have been some minor changes to results in this post due to correction by the WAEC. The most significant change concerned a correction to the count in Southern River which cut the Labor two-party preferred vote from 84.9% to a still substantial 83.1%.)

2017 Tasmanian Redistribution

With rumours swirling that an early Tasmanian election is set to be announced, there is one small piece of unfinished business I need to fix.

The 2021 Tasmanian election will be fought on new electoral boundaries and in this post I re-calculate the results of the 2018 Tasmanian election to match the new electoral boundaries.

2021 Federal Redistribution – Draft Boundaries for Western Australia

UPDATE 4 June – the AEC finalised the boundaries today with some minor nips and tucks. Data files have yet to be published, but the changes described in the final report do not suggests any significant changes to the new margins set out in this post. The new boundaries will be gazetted on 2 August, which perhaps gives a hint that the Prime Minister won’t be calling an election for Augsut.

Last year’s review of state representation in the House of Representatives recommended that Western Australia lose a seat, its representation falling from 16 to 15 members.

The draft boundaries are released at noon eastern time and I will update this post through the day with information on the new boundaries and estimated new margins.

In summary, the Liberal seat of Stirling is abolished and there is not much shift in margins for other seats.

The change in margins shown in the table below don’t show much shift in margins, but in going from 16 to 15 seats there are substantial changes in boundaries.

2021 Federal Redistribution – Draft Boundaries for Victoria

26 July 2021 – google searches still find this post but a much more complete analysis of the final boundaries has now been published at 2021 Federal Redistribution – Boundaries Finalised for Victoria This includes maps of the major boundary changes.

UPDATE 29 June 2021 – The boundaries have been finalised with various nips and tucks. New maps haven’t been published yet which makes it hard to calculate new margins. The major change appear to be the changes to Macnamara have been undone, and Tucker has reverted back to being known as Corangamite. I’ll review all the calculations after the map details are published on 26 July.

Last year’s review of state representation in the House of Representatives recommended that Victoria gain a seat, increasing its number of members from 38 to 39 seats.

The short story is the seat of Corangamite has been re-named Tucker and becomes a more urban seat centred on southern Geelong.

There is a new seat called Hawke covering Melbourne’s outer west and north-west fringe including Sunbury, Melton, Bacchus Marsh and Ballan.

Most urban seats have had some boundary changes. The transfer of Springvale and Noble Park from Bruce to Hotham means the two seats more or less swap margins. Chisholm is slightly weakened for Liberal Gladys Liu and suburb swaps between Macnamara and Higgins opens an opportunity for the Greens to pass Labor and win Macnamara.

Western Australian Election Updates

In this post I’ll try and provide updates of election results over the next few days.

Counting resume at 10am Perth time each day.

Labor has won a smashing victory, polling more than 60% of the first preference vote and more than 69% after preferences. Labor also looks to have overcome the malapportioned electoral system for the state’s Legislative Council and is set to be the first Labor government in the state’s history to win a majority in the upper house.

Commentary reflects the live results being updated on the ABC Elections website.

And if you are looking for Legislative Council predictions, you can find them with the output from my Legislative Council calculator.

Saturday 20 March

I’ll close this post now. All seats have been decided though counting continues ahead of the formal distributions of preferences next week.

On Sunday I hope to write a separate post on the Legislative Council count where the predicted numbers are still bouncing around.

Rates of ‘Below the Line’ Voting at the 2017 WA Legislative Council Election

This is a post for those who want to follow the output from the ABC’s Legislative Council election calculator once its starts running with live result data.

The calculator assumes that all votes cast are ticket or ‘above the line’ (ATL) votes. In close contests, the relatively small number of below the line (BTL) votes may impact on the prediction by causing a drift away from the party’s preference ticket.

For anyone interested in assessing the accuracy of calculator predictions, this post contains relevant data from 2017 on the rates of BTL voting by party, vote type and region.

In summary, the 2017 data indicates that the rate of BTL voting has little relationship to the region in which a vote is cast, or the type of vote (postal, pre-poll etc) used by a voter.

Where real differences occurs is in the relationship between a voter’s first preference party choice and the likelihood of choosing to cast a BTL vote. Read More »Rates of ‘Below the Line’ Voting at the 2017 WA Legislative Council Election

WA’s Experiment with Lower House Ticket Voting

Divided Senate ballot papers and Group Voting Tickets were first introduced for Senate elections in 1984. They were later adapted for use in the four mainland states with Legislative Councils, South Australia in 1985, NSW in 1988, Western Australia in 1989 and Victoria finally in 2006.

Divided ballot papers remain in use for electing upper houses in all jurisdictions. However, group voting tickets (GVTs), allowing parties to control between-party preferences, have fallen out of favour. GVTs were abolished in NSW in 2003, for the Senate in 2016 and in South Australia in 2018. GVTs are still part of the upper house voting system in Victoria and Western Australia.

All states except Western Australia adopted the Senate’s horizontal ballot paper where groups are listed left to right, with voters given the option of voting ‘above the line’ for party groups, or ‘below the line’ for lists of candidates. Western Australia finally adopted this ballot paper in 2017.

The original WA upper house ballot paper listed parties and groups vertically. Voters were given the choice of voting for groups on the left of the ballot paper, or for candidates on the right.

The reason Western Australia adopted a different ballot paper was because the design was intended to be used for both upper and lower house elections. The divided lower house ballot paper was used for three by-elections in 1988 but then abandoned before the 1989 state election.

A sample of the divided ballot paper used for the 1988 Ascot by-election is shown below.Read More »WA’s Experiment with Lower House Ticket Voting

How to Vote in the Western Australian Upper House

It is VERY important that voters understand that the rules for voting in the WA upper house, the Legislative Council, are not the same as those used at the last two federal Senate elections.

Ahead of the 2016 Federal election, the rules for Senate voting were changed. Party control over preferences was ended by the abolition of group voting tickets (GVTs), previously used by parties to control preferences. The new system put control over between-party preference entirely in the hands of voters, the same as applies at lower house elections.

But these changes do not apply for WA Legislative Council elections.

This post is a Q&A explaining the differences and giving some hints on how to complete your Legislative Council ballot paper.Read More »How to Vote in the Western Australian Upper House
