The offender was found guilty by a jury of aggravated assault after stabbing the victim twice in the back with a large knife in an unprovoked attack.
He was also found guilty of two counts of failing to comply with a probation order.
The court considered the offender's serious criminal record, his difficult upbringing, and his Aboriginal background under Gladue principles.
The court sentenced the offender to 5 years' imprisonment for the aggravated assault and 9 months concurrent for the probation breaches, less credit for pre-sentence custody, resulting in a net sentence of 1 year and 102 days.
