Draft Victorian State Electoral Boundaries Released

I have double checked all my calculations and this post has been re-written to include an electoral pendulum for the draft boundaries as well as an updated table of margin changes.

UPDATE: I’ve published a report on the make-up of all electorates. You can find it at this link.

You can find maps of all new districts, details of changes, and the Commissioner’s reasoning for the changes on the Electoral Boundaries Commission website.

In broad summary, the major changes produced by the redistribution are –

  • The Electoral Boundaries Commission listed 10 seats as abolished and 10 created, but some of these are merely name changes to represent shifts in boundaries.
  • In net terms, the redistribution has abolished two seats in Melbourne’s eastern suburbs and created a seat each in Melbourne’s outer west and outer north-west. One middle-distance south-east Melbourne seat has been abolished and replaced by a new seat on Melbourne’s south-east fringe.
  • Boundary changes are extensive in the eastern suburbs, but the impact can be summarised as follows. Burwood (ALP 3.3%) has been replaced by Ashwood (ALP 2.1%) and Forest Hill (LIB 1.2%) replaced by Glen Waverley (LIB 0.8%). Ferntree Gully (LIB 1.6%) and Mount Waverley (ALP 1.8%) have been abolished. Bayswater flips from being a Labor seat (ALP 0.4%) to a notional Liberal seat (LIB 0.9%).
  • South-eastern Keysborough (ALP 14.9%) has been abolished and the new seat of Pakenham (ALP 3.0%) created on Melbourne’s south-east fringe. In associated changes to create Pakenham, Gembrook (LIB 0.8%) is replaced by Berwick (LIB 1.0%), Bass flips from (ALP 2.4%) to (LIB 2.4%), and Hastings goes the opposite way, switching from (LIB 1.1%) to (ALP 0.4%).
  • Prahran (GRN 7.5% v LIB) has become a Labor seat based on the new boundaries, though this in no way suggests the Greens won’t win the contest in 2022. The change in first preferences on the new boundaries sees the Liberal vote slip from first place on 34.5% to second on 29.5%, Labor rises from 28.9% to 33.3%, while the Greens stay in third place with the party’s vote down slightly from 28.1% to 27.9%. This translates into a 5% two-party shift from Liberal to Labor and makes it harder for the Greens to win from third place on Labor preferences as they have at the last two elections. But again, this doesn’t mean the Greens can’t or won’t win on the new boundaries in 2022.
  • West of the Yarra, Altona (ALP 14.6%) is replaced by Point Cook (ALP 12.4%) and there is a new seat called Laverton (ALP 24.0%).
  • In Melbourne’s north-west, well over quota Yuroke (ALP 20.3%) has been split into two news seats, Greenvale (ALP 22.3%) and Kalkallo (ALP 20.4%). Further east, Mill Park (ALP 24.0%) has been replaced by Morang (ALP 25.2%).
  • In western Victoria, Wendouree (ALP 10.3%) is replaced by Eureka (ALP 13.4%), the changes involved also switching Ripon (LIB 0.02%) to (ALP 2.7%). The Labor margin for Buninyong slips from 12.2% to 7.3%.
  • Seats weakened for Labor include Albert Park (13.1% to 9.2%) and Buninyong (12.2% to 7.3%). Strengthened are Narre Warren South (6.9% to 10.7%) and the Premier’s seat of Mulgrave (12.7% to 16.4%).
  • The Liberal margin in Polwarth slips from 5.4% to 2.3% as the seat moves deeper into the Surf Coast.
  • The Green margin in Brunswick increases from 0.6% to 2.3%.
  • Labor won 55 seats at the 2018 election. They lose Keysborough and Mount Waverley (abolished) and Bass and Bayswater (become notional Liberal). They gain Hastings, Prahran and Ripon on the new boundaries, and the new seats of Greenvale and Kalkallo (in place of Yuroke), Laverton and Pakenham. Labor now has a notional 57 seats.
  • The Liberal Party have slipped from 21 to 20 seats. The party has lost Ferntree Gully (abolished), Hastings and Ripon are notional losses to Labor, but notional gains are Bass and Bayswater.
  • The Greens notionally lose Prahran.
  • There is no significant change in the swing required for a change of government.

      Further notes on Non-2PP Contests

      Benambra – Liberal margin versus Independent nudges upwards from 2.4% to 2.6%.

      Geelong – Labor margin versus Independent 6.2% in 2018, new margin not calculated.

      Mildura – Independent Margin verses National 0.3%, gains 2,252 electors from Ripon, new margin not calculated

      Morwell – Unchanged, Independent margin versus Labor 1.8%.

      Pascoe Vale – Labor margin 8.6% versus Independent, major changes to boundaries make new margin impossible to calculate.

      Prahran – Green margin versus Liberal 7.5% in 2018. Greens won from third place on Labor preferences. Hard to work out a new margin. On first preferences, Liberal vote slips from first on 34.5% to second on 29.5%. Labor’s vote rises from 28.9% to 33.3% and the Green vote slips from 28.1% to 27.9%.

      Shepparton – Unchanged, Independent margin v Liberal 5.3%.

      Werribee – Labor margin versus Independent nudges up from 8.8% to 9.2%.
