How seats changed relative to Australia in 2025

June 19, 2025 - 09:15 -- Admin

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.

What might the 2PP be in Bradfield?

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.

The House-Senate vote difference

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.

Are seats getting closer? Maybe not

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.

Correcting some of the 2CP swings

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.
