A used car salesman who became radicalised by ISIS so quickly he was prepared to fight and die in Kashmir for the terror group has left a judge concerned whether the Melbourne father is still a risk.
Khaled Temssah, 32, has pleaded guilty to preparing to travel overseas to engage in hostile activity after he paid undercover police $880 for what he thought was an AK-47 and transport costs in June 2019.
Judge Justin Hannebery said while Temssah had disavowed his previously held extremist beliefs, he remained concerned about the speed in which they were developed.
"He was prepared to give his life within a period of months after the radicalisation started," Judge Hannebery told a pre-sentence hearing at the Victorian County Court on Monday.
"He wanted to join the mujahideen and die as a martyr in the Kashmir. That's an intense and absolute level of commitment to this type of thinking.
"(And) he was radicalised very quickly, so the danger of him changing his mind is still apparent."
This, Judge Hannebery said, meant Temssah only had "reasonable" prospects of rehabilitation, despite the fact he had, until the age of 28, lived a "successful life" with no convictions.
Temssah previously told the court in June he was radicalised through charity work after being exposed to the suffering of women and children in Kashmir.
"I felt really sad and upset that this was happening in Kashmir," he said.
"I felt obliged to go out of my way to make those people's lives as easy as possible."
Temssah watched videos including of beheadings and Osama bin Laden speeches.
The 32-year-old Roxburgh Park man told an undercover operative posting as an extremist on Wickr he wanted to join ISIS to "fight the idol worshipper tyrant".
He also googled "how to join ISIS" and "what part of Yemen is ISIS in".
But in court Temssah said he'd changed his tune and now considered the militant group as having "an evil agenda to push".
Judge Hannebery accepted that Temssah was motivated by "adopted grievances" from ISIS material, rather than any personal afflictions.
Prosecutor Ben Ihle described Temssah as "malleable" and argued that he had both radicalised and deradicalised quickly.
This, Mr Ihle argued, compromised his rehabilitation prospects.
But Temssah's barrister, Rishi Nathwani said his client had spent 804 days in custody, giving him plenty of time to deradicalise.
Mr Nathwani also said Temssah had shown genuine remorse for his actions.
He will return to court for sentencing on September 15.
