When the federal government signals it wants to prevent Australian citizens from returning home, the instinct of many voters is to nod along. National security is a legitimate concern, and the cohort in question, 34 women and children with links to the Islamic State, carries associations that make headlines uncomfortable to read. But instinct and law are different things, and in a country that prides itself on the rule of law, that difference matters enormously.
Australia does not have a constitutional provision that explicitly guarantees citizens the right to return. That might seem like a legal loophole the government could exploit, but the reality is considerably more complex. International law, to which Australia is a signatory through several binding instruments, is far less accommodating of blanket exclusions. The International Covenant on Civil and Political Rights, ratified by Australia in 1980, includes Article 12(4), which states plainly that no one shall be arbitrarily deprived of the right to enter their own country. Courts in comparable jurisdictions have interpreted "own country" broadly, including in cases involving citizens who have spent years abroad.
The government's primary legal tool in situations like this has been the Australian Citizenship Act 2007, along with amendments introduced in the counter-terrorism context. These provisions allow for citizenship to be stripped from dual nationals who engage in terrorism-related conduct. But a significant portion of the 34 individuals in question are children, some born overseas to Australian mothers, and many hold only Australian citizenship. You cannot strip someone of citizenship if doing so would render them stateless; that prohibition exists in both domestic law and international convention.
Where the legal tension sits
The adults in the cohort present a different, though still contested, picture. Women who travelled to join or support the Islamic State may face criminal prosecution under Australia's foreign fighter laws, which carry serious penalties. Prosecutors would need evidence sufficient to mount a case, and gathering that evidence from conflict zones in northern Syria is genuinely difficult. This is not a technicality designed to let dangerous people walk free; it is the basic evidentiary standard that any criminal justice system requires to function with integrity.
The Parliamentary Joint Committee on Intelligence and Security has previously examined questions around foreign fighters, and legal experts who appeared before similar inquiries have consistently noted that exclusion without trial is a fundamentally different proposition from prosecution after return. The former bypasses the judicial process; the latter uses it.
Civil liberties advocates and human rights lawyers argue, with genuine force, that denying return is itself a form of extrajudicial punishment. The children especially, who had no agency in the decisions that brought them to Syria, are arguably the most legally and morally difficult cases. Keeping minors in Syrian detention camps, some of which have been documented by aid organisations as dangerous and inadequate, raises its own serious questions about Australia's obligations under the UN Convention on the Rights of the Child.
The security argument taken seriously
None of this means the security concerns are fabricated or trivial. Intelligence agencies have legitimate grounds to assess whether returning individuals pose ongoing risks. Some of the women allegedly played active roles in Islamic State-controlled territory, not merely passive ones. A government that waved through every returnee without scrutiny would be failing its primary duty to protect the public.
The question, though, is not whether scrutiny is warranted. It plainly is. The question is whether exclusion rather than prosecution is the appropriate mechanism. Australia has invested substantially in its counter-terrorism legal framework since 2001, and that framework includes provisions for monitoring, control orders, and criminal charges. If those tools are inadequate to manage the risk posed by this cohort, that is a conversation worth having openly in parliament.
What does not serve the national interest is the government gesturing at legal powers it may not actually possess, creating an impression of control that could unravel in court. The High Court of Australia has shown in past cases that it will scrutinise executive action against citizens with considerable rigour. Any legal strategy built on shaky foundations risks both embarrassing the government and, paradoxically, producing outcomes that satisfy nobody.
Reasonable Australians can hold two things in mind at once: that national security is a genuine and pressing responsibility of government, and that the rule of law applies even in uncomfortable cases. A system of rights and legal protections that bends whenever the subject is unpopular is not much of a system at all. The harder, more honest conversation is about how Australia prosecutes, monitors, and where appropriate rehabilitates this cohort, not whether it can simply wish them away.
