A plane carrying some of the 19 Australian women and children held in Syria since the defeat of Islamic State has landed in Melbourne, with the remainder due to land in Sydney on Tuesday evening.

The cohort of 12 children and seven women left a Syrian detention camp last week before boarding flights home. Most either left Australia more than a decade ago, or were born in Syria or Iraq after their parents travelled to the so-called caliphate.

The home affairs minister, Tony Burke, said on Tuesday morning that security agencies have been preparing for their return since 2014 and “have longstanding plans in place to manage and monitor them”.

“These are people who have made the horrific choice to join a dangerous terrorist organisation and to place their children in an unspeakable situation,” he said.

“As we have said many times, any members of this cohort who have committed crimes can expect to face the full force of the law.

“The priority of the government, as always, is the safety of the Australian community.”

The Sydney group is expected to include Nesrine, Sumaya and Aminah Zahab and Hyam Raad, along with their children.

Aminah is the mother of Muhammad Zahab, who the ABC reported in 2019 was considered to be a senior member of IS who recruited more than a dozen family members before he was killed in 2018. He reportedly convinced Aminah and his sister Sumaya to also travel to Syria.

His cousin, Nesrine Zahab, has said she was 21 when she and a female cousin snuck away from a family holiday in Lebanon to help refugees on the Turkish side of the Syrian border.

She said she had no intention of entering the war-torn country.

“Who walks into a war zone? I was going to see Syrians, yes, because of what they’re going through,” Nesrine Zahab told the ABC.

“I found that I was in Syria, did I have a heart attack? Of course.

“Did I cry and scream and chuck a fit like a little girl? I chucked the biggest tantrum.”

The group returning to Melbourne was expected to include Kawsar Kanj and her five children, one of whom is now an adult, and Kirsty Rosse-Emile and her two children.

Kanj and her husband, Majed Raad – who was acquitted over his alleged role in the Pendennis terror plot almost two decades ago – travelled with three children to Syria from Melbourne’s northern suburbs in 2014. Two more children were born after the couple left.

According to documents seen by Guardian Australia, Kanj had her citizenship cancelled by then home affairs minister Peter Dutton in 2019 in a decision later overturned by a high court ruling.

Raad is thought to have survived the territorial collapse of IS and was held in a Syrian prison, but his current whereabouts is unknown.

Rosse-Emile was 19 when she left Melbourne’s south-east with her husband, Nabil Kadmiry. Their two children, aged about 9 and 6, were born after the couple left Australia. Kadmiry was also captured in 2019.

Members of Kanj’s and Rosse-Emile’s families did not respond to requests for comment.

Save the Children Australia CEO Mat Tinkler said the returning children would need access to “wraparound health and psychosocial support”.

“The political debate surrounding their future in Australia has been deeply disappointing,” Tinkler said.

“While much attention has focused on the circumstances of the mothers, two-thirds of the returning group are children. Australia must prioritise their safety, wellbeing and right to live in this country as Australian citizens.”

The Morrison government repatriated eight orphans from Syria in 2019 before the Albanese government repatriated 13 children with their four mothers in October 2022.

In 2025, two mothers and their four children returned to Melbourne after negotiating their return with authorities.

Last month, nine children and their four mothers also returned to Australia with the support of their families. Three of the women were arrested and charged.

Tinkler called for the remaining Australian woman in Syria, who has been issued a temporary exclusion order by the Albanese government preventing her return and has stayed in the country with her daughter, to also be allowed to leave.

The woman’s father and lawyer were contacted for comment.
