I’ve previously posted a number of times before about the dataset I have compiled of election results since 2004, adjusted for 2025 electoral boundaries.
Most recently, prior to the election, I specifically did a comparison of the 2007 and 2022 electoral map: two elections with similar two-party-preferred votes and a similar number of seats with a two-party-preferred majority for each major party.
Last week I wrote about the dilemma of how to estimate a two-party-preferred vote in Bradfield. An actual two-party-preferred count has not been conducted between Liberal and Labor in that seat, and may not be conducted for some time.
Ben is joined by Kevin Bonham to discuss the collapse of the Tasmanian government just 15 months after the last election, and to look at some of the early moves for independents to find a new party home.
The Australian Electoral Commission conducts a two-party-preferred vote in every seat, which is a count between Labor and the leading Liberal or Nationals candidate. In seats where the two-candidate-preferred vote is not Labor vs Coalition, they do the count later. With 35 seats now “non-classic”, the AEC needs to conduct those notional 2PP counts in more and more seats.
While there’s a lot of similarities in how Australians vote between the House and the Senate, they’ve never voted exactly the same. For a start, there are more options on the Senate ballot paper than the House ballot paper. Small parties will not run in all House seats (sometimes they run in very few) and thus can only attract Senate votes in many seats. This means the bigger parties have traditionally done better in the House, where they have less competition.
While my focus has been very much on the federal election, events have been developing in Tasmania, which culminated in a vote of no confidence on Thursday.
For this podcast Ben interviews two scrutineers about their experience in the recounts: Adelaide, a Liberal scrutineer from Bradfield, and KJ, an independent scrutineer from Goldstein. Ben also discusses the recount procedures he saw in Bradfield last week and the latest count updates from Monday afternoon.
We are still waiting for the final 2PP figures – they’ve finished in 149 seats and have even started the 2PP count in Bradfield now – but we now have basically all of the two-candidate-preferred figures in. We may not know the final Bradfield outcome, but for the purposes of today’s post it is close enough.
Yesterday’s final result in New South Wales was a bit of a surprise, with One Nation closing a primary vote margin of 0.21 quotas. Even after One Nation won another senator in Western Australia on Thursday afternoon, the gain they had made in WA wouldn’t have been another to do the same in NSW.
Prior to the election, I drew attention to the differences between my calculations and those of the AEC for a number of non-classic seats that gained new areas during the redistribution. Originally I had a list of 14 affected seats, but one of them (Nicholls) has reverted to a classic contest.
