The Victorian Joint Counter Terrorism Team's investigation into an alleged arson attack on a Melbourne defence company has generated predictable debate about whether the incident constitutes terrorism. That question is important and, ultimately, one for investigators, prosecutors and the courts. But the more important strategic question is what the investigation reveals about Australia's democratic guardrails.

Over time, we’ve allowed the public boundary between peaceful protest, civil disobedience, criminal coercion and terrorism to become increasingly blurred. Restoring that boundary is no longer simply a matter of criminal law; it’s becoming a question of democratic resilience.

On 5 July 2025, a group of unknown people vandalised of property Melbourne-based defence manufacturer Lovitt Technologies, including setting vehicles alight. Lovitt makes aerospace components, including for the global F-35 fighter program.

The joint counterterrorism team – comprising the Australian Federal Police, Victoria Police and the Australian Security Intelligence Organisation – said yesterday it was investigating the attack as an ‘act of terrorism, potentially orchestrated by far-left extremists with anarchist and revolutionary ideologies.’

Australia's democratic tradition has been strengthened by peaceful protest. Campaigns for women's suffrage, Indigenous rights, workplace reform, environmental protection and opposition to apartheid demonstrate that democracies depend on citizens challenging governments and institutions. But liberal democracies derive their legitimacy not simply because they tolerate dissent but because political disagreement is resolved primarily through persuasion rather than coercion. That distinction is one of democracy's greatest competitive advantages over authoritarian systems.

The issue isn’t whether Australia has become more politically divided or even more politically violent. The issue is whether Australians have become less certain about where legitimate political persuasion ends and illegitimate coercion begins. Once that distinction weakens, the language, norms and institutions that sustain democratic legitimacy begin to drift.

Healthy democracies balance competing rights. Citizens have the right to protest peacefully and criticise governments. Police officers have the right to perform their lawful duties without assault or intimidation. Employees have the right to attend work safely. Businesses have the right to conduct lawful activities without criminal interference. Communities have the right to move freely, access essential services and expect public order to be maintained. None of these rights is absolute. Democratic resilience depends on maintaining an appropriate balance between them.

That balance has become harder to sustain because Australia's public vocabulary has become increasingly imprecise. Trespass becomes ‘direct action’. Deliberate obstruction becomes ‘disruption’. Property damage is described as ‘non-violent resistance’. Assaults on police become ‘clashes’. Equally, governments sometimes contribute to the same confusion by reaching too quickly for the language of extremism when responding to unpopular activism. Democracies require language that accurately describes conduct rather than language that either legitimises or exaggerates it. Language shapes legitimacy, legitimacy shapes social norms, and social norms shape behaviour.

Australia needs to restore a shared democratic taxonomy for political action. Peaceful protest communicates ideas without committing offences against others. Civil disobedience deliberately breaches the law while openly accepting legal consequences. Criminal coercion employs unlawful conduct to impose operational, financial or psychological costs on others in pursuit of political change. Politically motivated violence deliberately uses violence or serious intimidation to advance ideological objectives. Terrorism remains the narrower statutory category reserved for conduct intended to intimidate the public or coerce governments through serious harm. Democracies cannot respond proportionately if they first lose the ability to distinguish between these different forms of political action.

No single institution is responsible for the erosion of these boundaries. Activists seek language that legitimises their tactics. The media simplifies complex events. Politicians often respond according to whether they support the cause rather than the conduct. Police, prosecutors and courts make individual operational and legal decisions that are often entirely reasonable. Collectively, however, their continuous, concurrent and cumulative effect has been to weaken a once well-understood distinction between persuasion and coercion.

History demonstrates that political escalation is usually evolutionary rather than revolutionary. Australian examples include anti-apartheid protests in response to the South African rugby team’s 1981 tour; environmentalist protests against the proposed Franklin Dam in Tasmania in the early 1980s; anti-lockdown demonstrations; and campaigns targeting defence companies. These experiences have shown that while the overwhelming majority of protesters remain peaceful, smaller groups often adopt increasingly coercive tactics as less extreme methods lose political effect.

Each successful unlawful protest teaches participants what attracts media attention, how police respond and what legal consequences are likely to follow. It reinforces group cohesion, normalises previously exceptional conduct and encourages increasingly disruptive tactics. None of this inevitably leads to terrorism, but it explains why democracies should pay close attention to incremental coercion long before terrorism legislation becomes relevant.

This also explains why civil disobedience shouldn’t be confused with criminal coercion. Gandhi, Martin Luther King Jr and many suffragettes accepted punishment because they sought to demonstrate the injustice of particular laws while reaffirming respect for the broader rule of law. Their willingness to bear legal consequences strengthened rather than weakened the legitimacy of their movements. That differs fundamentally from arguments suggesting political conviction should reduce criminal responsibility because a cause is morally urgent.

Governments, however, must exercise equal discipline. Democracies damage themselves when they conflate peaceful protest with extremism, rely unnecessarily on extraordinary powers or respond disproportionately to lawful demonstrations. Democratic resilience depends upon consistent, proportionate and politically neutral enforcement of ordinary criminal law while preserving a broad and confident space for peaceful dissent.

These questions have become more urgent because Australia's strategic environment has changed. Political polarisation has intensified. Social media rewards confrontation. Overseas conflicts are rapidly imported into domestic politics. Foreign actors exploit social divisions through information operations. ASIO has warned that politically motivated violence is becoming more ideologically diverse, while major operations such as the deployment of almost 1,800 Victoria Police officers each day during the 2024 Land Forces protests illustrate the growing demands placed on democratic institutions.

Whatever conclusions investigators ultimately reach in the Melbourne arson investigation, Australia should use the case to restore one of democracy's most important guardrails. Democracies don’t lose the distinction between persuasion and coercion through a single dramatic event. They lose it gradually as language, norms and institutional practice drift until increasingly coercive behaviour is accepted as simply another form of protest. Re-establishing that boundary is not about limiting dissent. It’s about preserving democracy's greatest strategic advantage: the ability to resolve profound political disagreement by convincing fellow citizens rather than compelling them.
