Every time Australia’s political debate descends into culture-war territory, every time you despair at the quality of public discourse, every time you look at what is happening in the United States and wonder how a democracy can become so dysfunctional — remember this: Australia has compulsory voting, and it is one of the most important democratic safeguards we possess.
It is also one of the least appreciated, least discussed, and most frequently misunderstood features of our democracy. And in a political environment where extremism is rising on both ends of the spectrum, it deserves a serious defence.
What Compulsory Voting Actually Does
In Australia, all eligible citizens are required to enrol and attend a polling place on election day. Technically you are required to have your name marked off and receive a ballot — you are not legally compelled to actually mark it (informal votes are permitted). In practice, the vast majority of Australians cast a valid vote, and informal voting rates are low.
The effect on the electorate is profound. In voluntary-voting countries like the United States and United Kingdom, turnout in national elections typically runs between 50% and 65%. In Australia, turnout is consistently above 90%. This is not a trivial difference. It is a fundamentally different electorate.
In voluntary-voting systems, the people who vote are disproportionately the people who care most intensely about politics — which means they are disproportionately the people at the ideological extremes. The political middle — the people who are busy, disengaged, or just getting on with their lives — tends not to vote. This systematically distorts what elections measure. It means that primary elections, in particular, are decided by small numbers of highly motivated partisans, which is a significant part of why the United States has produced increasingly extreme candidates on both sides.
Compulsory voting forces the disengaged middle to participate. It means politicians must appeal to ordinary people who don’t spend their evenings on political Twitter, who don’t have strong ideological commitments, and who will vote for whoever seems most competent and reasonable. This creates a powerful structural incentive toward moderation.
Why It Limits the Power of Extremism
Consider what makes Donald Trump viable as a political candidate in America. His support base is intensely motivated, deeply partisan, and turns out to vote at high rates. The Americans who find him alarming but are not particularly politically engaged — the exhausted middle — are precisely the people least likely to show up at the polls to stop him.
In Australia, that calculation changes fundamentally. Every eligible citizen votes. The Australians who find extremism alarming but are busy living their lives still participate. The election is decided not just by the politically passionate but by the full spectrum of the population, including the enormous, largely moderate middle that forms the majority of any democracy.
This doesn’t make extremist parties impossible in Australia — One Nation’s polling surge demonstrates that. But it does mean that parties at the ideological extremes face a much harder electoral environment than in comparable voluntary-voting democracies. They must appeal beyond their passionate base. They must offer something to the disengaged voter who has shown up at the polling place primarily because they legally have to, not because they are burning with ideological conviction.
The Common Objections
“It infringes on freedom.” This is the most common objection, and it has surface-level appeal. But we accept compulsory participation in many aspects of civic life — jury duty, census participation, paying taxes — without treating these as fundamental attacks on liberty. The argument that being required to attend a polling place (not to mark a ballot in any particular way, just to show up) is an intolerable infringement on freedom is an extreme libertarian position that most Australians do not hold, and for good reason. The right to abstain entirely is already accommodated through informal voting.
“An uninformed vote is worse than no vote.” This argument has a whiff of elitism that it rarely acknowledges. The implication is that some voters — the politically disengaged — are too ignorant to be trusted with the ballot, and democracy would be better served by their exclusion. History is not kind to this argument. The populations that benefit most from democratic participation are often precisely those who would otherwise be least likely to vote. And the evidence does not show that low-information voters make systematically worse choices than high-information ones — they just make different ones, ones that tend toward the pragmatic centre rather than the ideological extreme.
“It’s undemocratic.” The counterargument is strong: a democracy that only hears from the most ideologically engaged portion of its population is producing a systematically distorted picture of what the population actually wants. Compulsory voting makes elections a truer measure of the whole society, not just its political activists.
Don’t Take It for Granted
There are periodic calls in Australia to make voting voluntary — usually from the political right, on the grounds that this would advantage parties with more motivated bases. These calls should be resisted firmly and on principle.
Compulsory voting is not a trivial procedural quirk. It is a structural feature of our democracy that has contributed materially to Australia’s political stability, its resistance to the worst forms of extremism, and its consistent production of governments that at least nominally represent the will of the whole electorate. It is one of the reasons we have not had our Trump moment — yet.
In a moment when democratic institutions around the world are under genuine stress, it seems like exactly the wrong time to dismantle one of our most effective defences against political extremism — especially when it’s dressed up as expanding freedom.
