On 21 May 2020 he was sentenced to ten years jail, with a seven and a half years non-parole period. In December 2020 his sentence was increased to sixteen years, with a non-parole period of twelve years.

Counterterrorism efforts Australians joining external conflicts The Islamic State of Iraq and the Levant (ISIL), proscribed by the government as a terrorist organisation, has targeted Australian Muslims for recruitment. Making use of social media, recruiters target those vulnerable to radicalisation, and encourage local jihad activities. Some of those targeted have been minors, including a 17-year-old who was arrested in Melbourne in May 2015 for plotting to detonate home-made bombs, and sentenced to 7 years jail. In June 2014, the government claimed that roughly 150 Australians had been recruited to fight in the conflicts in Syria and Iraq. A list released in April 2015 showed that most were young males who have come from a range of occupations, including students. It was also reported at the time that 249 suspected jihadists had been prevented from leaving Australia. The Australian Border Force Counter-Terrorism Unit, tasked with stopping jihadists from leaving the country, had cancelled more than 100 passports
