Sunrise host Nat Barr unleashes after another alleged stabbing in Sydney

Nat Barr has questioned if deradicalisation programs are working after a university student was stabbed in the neck by a 14-year-old boy who was charged with planning a 'Christchurch-like' terrorist attack at a school last year.

The teenager, wearing an army camouflage uniform, walked up behind the 22-year-old man and allegedly stabbed him in the neck and back near the main entrance of the University of Sydney on Tuesday morning.

Emergency services rushed to the university at about 8.35am and took the student by ambulance to the Royal Prince Alfred hospital.

The teenager allegedly fled the scene before he caught the bus to the same hospital where he was arrested and treated for minor hand injuries.

It has now been revealed the 14-year-old was charged with planning a 'Christchurch-like' terrorist attack at an inner-city school in Sydney last September.

He allegedly made violent threats to his classmates that mentioned the Christchurch mosque shooting in New Zealand in 2019, which left 51 people dead.

The charges were dismissed in Surry Hills Children's Court on mental health grounds in February of this year, and the teen entered a deradicalisation program.

Barr asked former police detective Peter Moroney if the government needed to provide people with more support at the conclusion of the programs.

'These deradicalisation programs, I understand, are funded by the federal government and run by the states,' she said. 'Do we need to re-look at what happens after them? Because this kid was only in one five months ago I think.'

'It would be timely now, particularly in light of the three or four young individuals that have been arrested over the last six months,' Mr Moroney replied.

'It never hurts to stop and ask have we got this right, is there anything else in addition that we could be doing?

'From an Australian government perspective, we're putting over $150million into these deradicalisation programs. We want to know as the average taxpayer are they working? Are they doing what they should be doing?

'And if not, we've got to ask those questions and hold these systems and these processes to account.'

'Yeah, just ask the poor family of the 22-year-old who was stabbed in the neck yesterday at Sydney Uni,' Barr said.

Mr Moroney said the deradicalisation programs could be effective but that further monitoring and support afterwards was vital.

'I think what's most troubling about these ones is the age of these children,' he said.

'At some point they're going to be part of an educational facility, they're probably enrolled in school, whether they're attending or not.

'The deradicalisation programs are a point in time program, so whilst they might go through that program, they might get what they need whilst they're in the program, once they conclude that program, what monitoring and support are they given?

'Because it's essential, if they fall back into that cycle, off we go again and we'll end up where we're ending up right now.'

NSW Police sources told mediathat terror is a likely motive for the attack. The 14-year-old is known to police and government agencies.

A joint counter terrorism taskforce has tasked NSW Police, the Australian Federal Police and other government agencies with the investigation.

The teenager and his alleged victim were not known to each other.

Photos of the deserted campus showed a backpack and a puffer jacket discarded at the entrance beside what appeared to be a bloodstain.

Sydney University Vice Chancellor Mark Scott said he was 'shocked and saddened' by the incident said the victim's family had been offered support.

A university spokesman said security had been boosted at the university.

'As a precautionary measure there may be an increased security and police presence on campus while investigations continue,' he said.

'The safety and wellbeing of our students, staff and members of the community is our priority, and we continue to work with authorities.
