One Nation has backed proposed federal legislation aimed at stopping people from helping Australians linked to Islamic State return from Syria, intensifying a national debate over security, citizenship and the treatment of children held in detention camps.

The proposal has been promoted as a way to close what supporters describe as a legal loophole. It would create stronger criminal consequences for people who knowingly assist certain Australians connected to designated terrorist areas to travel home.

What the proposal is trying to do

Australia already has laws covering terrorism, foreign incursions, association with terrorist organisations and travel to declared areas. Authorities can also use temporary exclusion orders to delay and control the return of an Australian citizen where legal thresholds are met.

The new bill seeks to add another offence focused on people who facilitate a return. Supporters say the government should not be able to rely on outside organisations or private individuals to arrange travel for people who chose to join or support Islamic State.

One Nation senator Malcolm Roberts has argued in Parliament that Australians who travelled to the former Islamic State territory should face responsibility for their decisions. The party says national security must take priority and that anyone suspected of terrorism-related offences should be investigated and, where evidence permits, prosecuted.

Legal limits remain

Australian citizens generally retain a right to enter their own country. Legal experts have said the government cannot permanently exclude a citizen simply because their return is politically unpopular. Temporary exclusion orders can impose conditions and delay travel, but they operate within statutory and constitutional limits.

That distinction matters because the Australians who have remained in Syrian camps include women and children, and the evidence concerning each person is different. Association with an Islamic State fighter does not by itself establish that a person committed a criminal offence.

Security agencies assess individual cases

Federal authorities say returning individuals can be assessed, monitored and investigated. Control orders, passports, surveillance and prosecution may be available depending on the evidence. Any charge must still be proved in court, and children require separate protection and rehabilitation considerations.

Critics of the proposed offence question whether it could criminalise humanitarian help or complicate the safe return of children. They argue that bringing people into a system where Australian police, courts and security agencies can manage the risk may be safer than leaving them in unstable camps.

The political choice

The debate is not simply about whether Australians support Islamic State—there is broad rejection of the terrorist organisation. The harder question is how a democratic country should respond when its citizens, including children, remain overseas after the collapse of the group’s territory.

Parliament will need to examine the wording carefully: who qualifies as an ISIS-linked Australian, what level of knowledge would trigger liability, what exemptions would apply, and how the law would interact with existing exclusion-order and terrorism offences.
