A far-right extremist who hailed the Christchurch mass murderer as a "saint" online has been jailed for at least 14 months.
Tyler Jakovac, 20, from Albury, pleaded guilty in March to advocating the commission of a terrorist act or offence in relation to extreme far-right posts online.
He was sentenced in Parramatta District Court on Monday to a total term of 18 months in prison after a 25 per cent discount was applied for his early plea.
Judge Mark Buscombe told his sentence hearing in May that he was very concerned about his description of the Christchurch mosques terrorist.
At the time of his arrest police said he used the web service Telegram to urge violence and the killing of "non-whites, Jews and Muslims".
The court was told that Jakovac as a youth became fixated with Russian and Slavic culture and held racist views against Jews and other minorities, before creating a Telegram channel when he was 17.
Crown prosecutor Rob Ranken conceded the young man appeared to be developing a renunciation of his racist views.
But he cautioned: "There does remain a risk that he may fall back into holding those views".
Jakovac's barrister Tom Quilter submitted there was a disconnect between his client's life and that of his online actions.
He asked the judge to spare him jail time, citing his autism spectrum disorder, difficult upbringing, good prospects of rehabilitation, and that he was 18 years old at the time of the offence.
His mother Jane Lovelock previously told the court that her son did not socialise much and worked up to 60 hours per week as a chef alongside migrant co-workers who "loved" him.
"They were so shocked when this happened," she said.
The offender was eligible for release on parole on February 8, 2022, after backdating from the time of his arrest in Albury and incarceration in December 2020.
