3CP data sheds light on the close races

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...

The make-up of the marginal seat list

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...

How the vote split between the early vote and election day

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...

How the swing was distributed, and how the pendulum performed

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,...

Tasmanian candidates rush out

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...

How seats changed relative to Australia in 2025

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...

Getting closer to the Bradfield 2PP

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. At the time I attempted...

Podcast #151: Tasmania goes back to the polls

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. This podcast is supported by the Tally Room’s...

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...

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...
