FED2025 – Independent Two-Party Preferred Preference Flow Data
The 2025 House of Representatives election was the first where more than a third of primary votes were cast for ‘Others’.
In total, minor parties and Independents recorded 33.6% of the primary vote. This was more than 31.8% for the Coalition and only one percent short of Labor’s vote.
The rise in support for ‘Others’ has changed the nature of seat contests at House elections. Elections today are far removed from the days when almost all seats finished as two-party preferred contests between Labor and the Coalition.
The word ‘classic’, which I’ve always associated with vintage cars and ice cream marketing, has been adopted by the Australian Electoral Commission (AEC) to describe traditional Labor versus Coalition contests. Or rather the AEC calls all other combinations of final candidates after preferences as ‘Non-Classic’, which it helpfully provides a list of on its election results website. (2025 list here)
In this post I’m providing information on two-party preferred preference flows in these Non-Classic seats, data that has not previously been available. This includes preference flow splits between Labor and the Coalition from votes cast for Independents in Non-Classic contests.
Until 1983, preferences were only distributed in seats where no candidate reached 50% of the primary vote. The AEC began to conduct distributions in all seats for ‘information purposes’ in 1984. That election saw every seat finish as a two-party preferred race.
Every election since has seen at least one Non-Classic contest. And as the chart below shows, the numbers have ballooned at the last four elections.
The chart above is based on all Non-Classic contests. The last three elections have seen a particular surge in these contests involving Independents. In 2019 there were seven final counts that involved Independents, rising to 16 in 2022 and 20 in 2025.
The AEC continues to do full distributions of preferences to the final pairing of candidates in every seat. Since the 1990s it has also undertaken alternative two-party preferred counts in every seat. (Except in Bradfield in 2025 for reasons explained later.)
The AEC counts preferences in two ways. First is by conducting the legally required full distribution of preferences in every seat to produce a two-candidate preferred count. Second, the AEC tallies what are called ‘preference flows’ in every seat for both two-candidate and two-party preferred finishes. I’ll describe how preference flows are calculated inside the post.Read More »FED2025 – Independent Two-Party Preferred Preference Flow Data
