2022 Federal Electoral Pendulum

With redistributions of electoral boundaries now complete for Victoria and Western Australia, it is time to publish an updated electoral pendulum for the 2022 election.

The redistributions have abolished the WA Liberal seat of Stirling and created the new notionally Labor held seat of Hawke in Victoria. (See my previous posts on the redistributions, in Victoria here and Western Australia here.)

Compared to the 2019 election result, the changes reduce the Coalition from 77 to 76 seats and lift Labor from 68 to 69 seats. In the 151 member House of Representatives, 76 seats are needed for majority government.

As well as the web formatted pendulum inside this post, I’ve prepared a well laid out printable ‘pdf’ version with seats listed in double-sided A4 format. You can find it at this link.

2021 Federal Redistribution – Boundaries Finalised for Western Australia

The draft Federal electoral boundaries for Western Australia released in March were finalised at the end of June.

Today the supporting documentation has been published, including the the new maps and enrolment data. That allows me to calculate estimated margins for the new boundaries. There are only minor changes compared to the draft boundaries released in March.

The overall summary of the redistribution’s impact is that the Liberal held division of Stirling has been abolished. This has caused major changes to the boundaries of Cowan, Pearce and Hasluck, with smaller changes propagating across the rest of the state.

The re-drawn electorate of Cowan includes a roughly equal number of voters from the old Cowan and the abolished Stirling. Pearce has been completely re-arranged, losing its former rural component to Durack and O’Connor, and the rapidly growing suburban areas around Ellenbrook to Hasluck. Pearce is now based entirely in Perth’s northern suburbs. Read More »2021 Federal Redistribution – Boundaries Finalised for Western Australia

2021 Federal Redistribution – Boundaries Finalised for Victoria

Draft Federal electoral boundaries were released in March and finalised at the end of June.

Today the supporting documentation, the maps and enrolment data, have been published which allows me to publish estimated margins for the finalised boundaries.

There were two changes of significance from the draft boundaries. Most of the proposed suburb swaps between Macnamara and Higgins have been reversed, and the proposal to re-name Corangamite as Tucker has also been abandoned.

The overall summary of the redistribution is that all 38 continuing seats remain held by the party that won the division in 2019, and the newly created 39th division is called Hawke and is a safe Labor seat.Read More »2021 Federal Redistribution – Boundaries Finalised for Victoria

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.

Victorian State Redistribution with Major Political Implications Starts this Week

The Victorian Parliament began its final sitting week today after a year where the parliamentary schedule has been heavily interrupted by Covid-19.

Parliament rises for the year on Thursday just as a major electoral event gets under way that will have major consequences for the November 2022 state election.

Thursday’s Government Gazette will carry the formal notice triggering a redistribution, a re-drawing of the state’s electoral boundaries.

It is a process with major implications for the electoral prospects of the Andrews Labor government and the Liberal and National opposition.

The scale of Labor’s victory in November 2018 always meant it would be difficult for the Liberal and National Parties to make up enough ground to win the next election.

The redistribution will make that task even harder.

On current enrolments, the redistribution will abolish several seats in Melbourne’s eastern suburbs, the Liberal Party’s traditional electoral heartland.

Those seats will be replaced by new seats on Melbourne’s south-east, western and north-western fringe, areas that have been dominated by the Labor Party at recent elections.

Barring events that alter traditional voting patterns, prospects are that the redistribution will buttress the Andrews’ government hold on office, and make victory for the Liberal and National Parties in 2022 just that little bit harder.

New State Electoral Boundaries for South Australia Finalised

(Post re-written and updated 20 November)

South Australia’s Electoral Districts Boundaries Commission (EDBC) released the final version of the state’s new electoral boundaries on 18 November. The new boundaries will apply for the first time at the next South Australian election in March 2022.

The final boundaries unwound some of the more consequential changes proposed by the draft boundaries. After much opposition, Mount Barker was retained in Kavel, leaving that seat based in the Adelaide Hills, and allowing Schubert to be a Barossa Valley based seat. Flowing from this, the proposed move of Gawler into Schubert was undone, unravelling major changes to Light and resulting in a string of further changes to seats across northern Adelaide.

The final boundaries also unwound a series of suburb swaps between the inner-southern Adelaide seats Badcoe and Elder with political consequences for the margins in both seats.

If you are after more detail on the composition of the new electorates, maps can be found on the EDBC’s website.

In this post I’ll provide some commentary on the approach taken by the EDBC and the political consequences that flow from the changes.
