Australia’s renewed controversy over citizens returning from former Islamic State territory has produced plenty of political outrage—but far less explanation of what the law actually allows.
Home Affairs Minister Tony Burke has acknowledged that Australian citizens cannot simply be permanently barred from entering their own country. That does not mean the Albanese government invited them back, arranged their travel or approved of their actions.
It means the government must operate within Australian law.
In May 2026, four Australian women and nine children linked to families that had lived in Islamic State-controlled territory returned from Syria. The government said it had not assisted their journey and warned that any adult suspected of committing an offence could face arrest and prosecution after arriving in Australia.
The distinction matters.
There is a major difference between helping someone return and recognising that an Australian passport holder has legal rights that cannot be erased by a ministerial announcement, political slogan or social media campaign.
The government does have powers
Claims that the government is completely powerless are also misleading.
Australia’s temporary exclusion order system allows the Home Affairs Minister to prevent an Australian citizen of counterterrorism interest from returning for up to two years. A return permit can subsequently control the timing of that person’s entry and impose conditions for up to 12 months after the person arrives.
Burke reportedly issued one exclusion order against a woman remaining in Syria after receiving advice from ASIO that she posed a national-security risk. However, none of the 13 people who returned in May were covered by such an order.
That is an important correction to the claim that the minister has no authority at all.
The government can delay a person’s return when the legal threshold is met. Authorities can investigate alleged offences, monitor people of concern, impose lawful controls and prosecute anyone where admissible evidence supports charges.
What the government generally cannot do is impose an automatic, permanent ban on every Australian citizen associated with Islamic State territory, regardless of their individual circumstances or the available evidence.
Citizenship cannot simply be cancelled
Removing citizenship is even more legally complicated.
Under the current Australian Citizenship Act, the Home Affairs Minister may apply to a court for an order ending a person’s citizenship. However, the person must be a dual national, must have been convicted of specified serious offences and must have received prison sentences totalling at least three years. The court must also find that the conduct was serious enough to demonstrate that the person repudiated their allegiance to Australia.
Citizenship cannot be removed when doing so would leave the person stateless.
Earlier laws allowing the minister to personally strip citizenship were struck down by the High Court. Parliament later replaced those provisions with a court-based process that commenced in December 2023.
Therefore, simply declaring that every suspected Islamic State supporter should lose citizenship does not solve the legal problem.
For sole Australian citizens, there may be no second country legally responsible for accepting them. Australia cannot ordinarily transfer its responsibility to another nation merely because dealing with the person is politically difficult or deeply unpopular.
Return does not mean immunity
Allowing an Australian citizen to enter the country does not protect that person from criminal consequences.
The Australian Federal Police said before the May arrivals that some adults could face arrest and possible charges. Authorities had been planning for potential returns for years, while security agencies were prepared to assess and monitor any continuing risk. The children were expected to receive psychological assistance and participate in programs intended to counter extremist influence.
Every allegation must still be investigated individually.
Living in territory controlled by Islamic State is not automatically identical to proving membership of a terrorist organisation, providing material support, committing violence or participating in another prosecutable offence. Police require evidence capable of surviving scrutiny in an Australian court.
That standard can be frustrating when alleged conduct occurred years earlier in a collapsed conflict zone. Witnesses may be missing, documents may have been destroyed and foreign intelligence may not always be admissible as courtroom evidence.
But abandoning evidence requirements would not strengthen Australian justice. It would weaken it.
This is not about whether Australians approve
Many Australians understandably have little sympathy for adults who voluntarily entered Islamic State territory or placed children in extreme danger.
The anger is real, and the security concerns should not be dismissed.
But the issue is not whether the public approves of those individuals. The issue is what powers the government possesses under the Constitution, citizenship law, counterterrorism legislation and the criminal justice system.
Politicians demanding that the government “just stop them” should explain precisely what law they would change, how the new power would operate and whether it would survive a High Court challenge.
That includes Pauline Hanson and every other politician presenting this as nothing more than a question of political will.
Even a government led by Hanson could not simply ignore citizenship law, court decisions and constitutional limits. Parliament could attempt to introduce stronger legislation, but ministers would still be required to follow valid laws and judicial rulings.
The real debate Australia should have
Australians are entitled to demand strong protections.
That may include tightly controlled return permits, intensive monitoring, prosecution where evidence exists, restrictions authorised by courts and properly funded rehabilitation programs for children who had no control over the decisions made by adults.
Parliament can also examine whether the current temporary exclusion system is strong enough and whether investigators need additional lawful tools to prosecute offences committed overseas.
However, the public deserves honesty.
The return of Australian citizens is not proof that the government supports them, welcomes them or excuses alleged conduct. It reflects the legal reality that citizenship carries obligations for individuals—and responsibilities for the country itself.
People suspected of terrorism-related crimes should face the full force of the law.
But the government must use the law, not bypass it.
