Preferences Help Non-Majors Beat Major Parties Far More Than The Other Way Around

This article is about single-member electorates, and cases where preferences result in someone who did not lead on primaries winning the seat, and how this affects battles between the major parties and candidates from outside the major parties ("non-majors") for seats.  

I've written a few articles on here in which I discuss mistaken views held by many Australian supporters of minor right-wing parties on social media.  Many of them rail against preferential voting, which they claim helps major parties to maintain a "duopoly" or "uniparty".  They often support scrapping preferences, although this would make it pointless to vote for the parties they support.  I've pointed out in these discussions that actually in the 2022 election, nine non-major candidates were elected from outside the parliament by beating one major party with help from the preferences of the other.  If there were no preferences, such candidates would need to rely on very organised strategic voting for any chance of winning.  Probably many would have lost.

Despite this, people keep claiming that the major parties conspire to keep smaller parties out of parliament by doing preference deals with each other so that if a smaller party leads on primaries the majors can beat them on preferences.  The supposed prime example is the defeat of Pauline Hanson in Blair 1998.  But the fact is that Hanson's loss was actually an unusual case, and examples of both majors cross-recommending against a competitive opponent are nowadays rare.  Indeed, including state elections, even One Nation has more often beaten majors from behind thanks to preference flows than led on preferences and lost, by a margin of 9 cases to 4.

I thought I would compile a list of all the cases I could find in single seat elections since 1990 (state, federal and territory) where either a major party has led on primary votes but been beaten by a non-major, or the other way around.  What I find is that non-majors beating majors by overtaking a major party primary vote leader on preferences is about nine times more common than the reverse.  


In all I've found 89 cases where non-majors have started behind a major party leader and then used preferences to overtake them (in a few of these cases even coming from third).  I've found just ten cases where a major beat a non-major who led on primaries, and in four of these the other major wasn't running.  Cases of non-majors overtaking major party primary vote leaders to win after preferences have happened frequently under both compulsory and optional preferencing.  

For the purposes of this analysis I have treated the Nationals (especially WA Nationals) as a major party irrespective of whether the state branch was part of the federal or state coalition at the time.  It's just too messy chasing all the divorces and remarriages otherwise, and it's kind of irrelevant to the point if the Nats beat the Liberals on preferences while on the crossbench then rejoin a coalition during the term.  

Here is the list.  At the bottom I discuss the few cases where a major party candidate overtook a non-major candidate who led on primaries, because some of these cases are artificial anyway.  A b after an election year means it was a by-election.  Cases where a major beat a non-major who led on primaries are shown in italics.  

It's possible I've missed a few, please let me know of any omissions; if there are any the text will be edited.

In all the Coalition parties are more often overtaken by non-majors (especially independents), losing 69 seats in this way since 1990 compared to Labor's 20.  

About the major overtakes of non-majors

The ten cases where majors have overtaken non-majors include four that are unusual and should be ignored in terms of the dynamics of general elections.

In the Tasmanian Legislative Council seats of Hobart 1994 and Rumney 1999 there was no Liberal candidate as at the time the party seldom contested, but many of the then-sitting independents were conservative and some had links to the party or were accused of doing so.  In the case of Hobart, Labor defeated a conservative independent because of the flow of Green voter preferences.   In the case of Rumney, the primary vote battle was very close and Labor actually beat the conservative independent on the preferences of voters for a maverick former Liberal who had a very low vote share. Tasmania does not have how to vote cards in state elections.

In the Victorian case of Mildura 2022, independent Ali Cupper had an artificial lead on primaries because both Liberal and National candidates ran against her.  Had only one Coalition candidate run she would not have led on primary votes.

In the strange Victorian case of the Melbourne 2012 by-election, there was no official Liberal candidate but an extremely large field of 16 candidates.  Greens candidate Cathy Oke outpolled Labor's Jennifer Kanis and led throughout the preference throw until the very last exclusion which sent pooled preferences from various minor candidates (including the unofficial Liberal) heavily to Labor, with Labor also helped here by the donkey vote.

The remaining six cases are more routine: four Queensland cases (three state, one federal) from 1998 where Labor preferences flowing to the Coalition defeated One Nation, and two cases where Liberal preferences flowing to Labor have defeated the Greens.  Although Coalition parties have sometimes recommended preferences to Labor candidates over One Nation candidates, I've found no case where this has caused a One Nation candidate who led on primaries to lose.  

Could there be an eleventh?

As I write the Liberals are just one vote ahead of the Greens in the Prahran by-election primary count.  (They will win the seat by about 1000 votes after preferences).  If this lead flips in checking during the preference distribution then this will be the first ever case of the Liberals beating the Greens on preferences from second on primaries, a thing unthinkable in Prahran on any normal day.  This will be another artificial case if it happens as Labor did not run, turnout was low, and as a key independent (Tony Lupton) appears to have both drawn primary votes from the Liberals and probably convinced some ALP supporters to follow his how to vote card which preferenced the Liberals.  [UPDATE: It didn't happen, the Liberals officially finished the primary count one vote ahead of the Greens.]
