Late on Monday, the AEC transitioned the election results website to its final archive form. You can now find the results at results.aec.gov.au, and the previous link no longer works.
There is probably enough fresh data to fuel a whole week of blog posts. I am planning to return to the question of the national 2PP and 2PP preference flows by party, as well as some deeper analysis of the 3CP trends across the country.
Earlier this month I published a blog post which discovered that the average 2CP margin of victory has not actually been getting smaller at recent federal elections. I didn’t end up including the chart in the post, but I also identified that the numbers of marginal seats hasn’t been going up over time, despite a number of formerly-safe seats now becoming marginal non-classic seats.
Last month I posted about the increase in the proportion of votes that were cast early (postal, pre-poll and remote) as opposed to those cast on election day. 55.7% of votes were cast early, with just 43.6% casting their votes on the day.
For today’s post I am looking at how those voters actually voted, and how it’s changed over time.
Now that we have a complete two-party-preferred vote for all of Australia, we can look at the distribution of seat margins and swings across the country.
For this post, I have produced a number of charts which show the distribution of seats by two-party-preferred result, and also by two-party-preferred swing. I also attempt to chart out the two-candidate-preferred swings in non-classic seats, or at least those which have a valid swing compared to 2022.
It has barely been two weeks since the no confidence motion passed, and just over a week since the Tasmanian state election has been called, but the candidates are coming out of the woodwork very quickly.
I have now updated my election guide to feature those candidates announced so far.
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.
