The arrival in Melbourne of a Qatar Airways flight on Thursday evening ended a long ordeal for the families of suspected Islamic State affiliates, but their freedom was measured in hours. Within minutes of disembarking, Australian Federal Police arrested two women: Kawsar Ahmad, 53, and her daughter Zeinab Ahmad, 31. A third woman, Jannat Saffar, 32, was detained separately in Sydney after landing with her young son. All three appeared in court on Friday charged with crimes against humanity, slavery, and terror-related offences. The arrests mark the first time Australia has pursued slavery charges against returnees from the Islamic State’s former caliphate—a legal watershed that analysts in London describe as an effort to balance security concerns with the messy reality of repatriation.

The women had spent years detained in the squalid Roj camp in north-eastern Syria, held by Kurdish-led forces after the collapse of the Islamic State’s territorial grip in 2019. They were among dozens of Australian citizens and their children who have languished there, caught between a host government unwilling to hold them indefinitely and an Australian government reluctant to bring them home. Viewed from Canberra, Prime Minister Anthony Albanese struck a deliberately ambivalent tone, expressing sympathy for the children—“victims of decisions made by their parents”—while insisting the adults deserved no public support. “I have absolutely no sympathy for these people,” he told reporters, a statement calculated to reassure a public still scarred by the 2014 Lindt Café siege and the 2017 Bourke Street attack.

The charges against Kawsar Ahmad, who is accused of travelling to Syria in 2014 and keeping a female “slave” in her home, rest on testimony gathered by Kurdish authorities and shared with Australian prosecutors. Her daughter faces two identical counts. In Sydney, Saffar is charged with entering and remaining in a conflict zone and joining a terrorist organisation. The trio were refused bail. The case now turns on whether Australia can prove that these women, while married to Islamic State fighters, actively participated in the group’s institutionalised enslavement of Yazidi women and girls. The evidentiary challenges are formidable, but legal experts note that Australia’s 2019 counter-terrorism legislation widened the definition of terrorism to include offences linked to sexual slavery—a shift that gives prosecutors a sharper tool than previous attempts to convict returnees.

Looking ahead, these prosecutions will test the limits of Australia’s willingness to reintegrate citizens who once embraced a violent ideology. The broader group of returnees, including sixteen children, now faces an uncertain future: their parents may be jailed, leaving minors to navigate the welfare system alone. Analysts in Washington point out that the United States, Britain, and several European states have quietly repatriated dozens of families, prioritising intelligence debriefings and deradicalisation programmes over prolonged detention. Australia, by contrast, has moved cautiously, and the courtroom drama unfolding in Melbourne and Sydney is likely to sharpen a national debate about whether punitive justice or rehabilitation should guide the final chapter of the Islamic State’s legacy.
