IS families in Syria have booked tickets home to Australia, minister says

He added that there were "very serious limits" on what the government can do to stop a citizen returning home.The government had been preparing for the group's return since 2014, Burke said, with "long-standing plans" to "manage and monitor them".Barrett added that for more than a decade, investigators had been collecting evidence on whether anyone in the group had committed "terrorism offences" as well as "crimes against humanity offences such as engaging in slave trading".She did not detail how many in the returning group of 13 would be arrested but confirmed that those who are not arrested would continue to be investigated.The children who return would "undergo community integration programs, therapeutic support and countering violent extremism programs".The head of Australia's spy agency, Mike Burgess, said he was not "concerned immediately" by the group's return but "they will get our attention as you'd expect"."It's up to them what they do when they get here, and if they start to exhibit signs that concern us, we and the police, through the joint counter-terrorism teams, will take action," Burgess, head of the Australian Security Intelligence Organisation (Asio) said, according to the Australian Broadcasting Corporation.Of the larger cohort of 34, 23 are believed to be children. The group had been living in the al-Roj camp in northern Syria since 2019, when IS was driven from its final foothold in Syria.
