On March 5, police searched the property where Managh was serving home detention and found 502g of cannabis head and plant. About 293g of cannabis was found in ounce-lot snaplock bags. Also found were two capsules of cannabis oil and two freshly-harvested cannabis plants, which had been stripped. The cannabis head found was worth more than $6000.
Managh's lawyer, Brian Foote, told the court Managh bought two cannabis plants and stripped them to sell some cannabis to make some money. Most of the cannabis was for Managh's own use.
Mr Foote said home detention had been very difficult for Managh because he did not have much to fill his days. Managh had been co-operative with police and had pleaded guilty.
Mr Foote handed a letter to the judge in which Managh expressed remorse. Mr Foote asked the judge to take into account Managh's young age and naivety.
Judge Cooper said when someone offended in a serious way while on home detention the only other option was jail.
The amount of cannabis involved was reasonably significant and a starting point was 15 months in jail. He reduced the sentence to 13 months because of Managh's guilty plea.
A Department of Corrections spokeswoman said offenders on home detention must report to their probation officer at least twice every 10 working days and on at least one of those occasions the probation officer will visit the offender at home.
She said probation officers do not search offenders' houses.
"The role of the probation officer is to ensure offenders comply with the requirements of their sentence of home detention. Probation officers take prompt and appropriate enforcement action when the offender does not comply," the spokeswoman said.
"We are satisfied that appropriate and timely action was taken when police identified that this offender possessed cannabis for supply."
