Moudasser Taleb, who was charged with shotgun offences in April, appeared in the NSW Supreme Court via video-link from jail on Tuesday.

In June 2019, Justice Peter Hamill placed him on a five-year good behaviour bond after taking into account the two years he already spent in custody.

The now 26-year-old had been found guilty of preparing to travel to Syria - between early February and mid-June 2017 - for the purpose of engaging in hostile activities.

He had no plane ticket and little money.

The jury rejected the defence claim that Taleb had no intention of engaging in warfare or was mentally ill at the time.

He was arrested at his Greenacre home in April and was charged with offences including acquiring a firearm and ammunition while subject to a firearm prohibition order and possessing an unauthorised prohibited firearm.

Taleb is also accused of breaching his Supreme Court recognisance order.

During his brief appearance on Tuesday, Justice Hamill was told the firearm matters were due to be heard in the Local Court in April.

The judge will be provided updated medical information, while the breach matter may depend on whether he is convicted or acquitted of the firearm charges.

He adjourned the breach matter for directions on May 9.

After an undercover police sting, Taleb was arrested at the airport in June 2017, with a bag containing military clothing, a sleeping bag, tactical gloves, a solar charger and other gear.

Taleb also had well over 200 videos on his phone including some showing beheadings, people with ISIS flags and battlefields.

After his arrest he was diagnosed with schizophrenia, a condition which the sentencing judge had a significant impact on his moral culpability.

Justice Hamill said he was in no doubt the decision to place Taleb on a good behaviour bond would be criticised by public commentators "who think no sentence is ever long enough".

But he said all the facts before him "cry out" for a sentence that would allow "the young, mentally ill and vulnerable offender" the chance of rehabilitation.

Taleb's impairment may have made him more susceptible to extremism and the offender was "an inappropriate vehicle" for a sentence of general deterrence, the judge said.

For the first two years of the bond Taleb was not to use messaging app Telegram, access any material controlled by IS or any other group espousing radical Islam and continue treatment for his mental illness.
