[21] Deterrence is an unquestionably important factor in sentencing offenders like the applicant who commit robberies of vulnerable small businesses. Her Honour was right to recognise that, despite the mitigating factors, both offenders had to serve a significant term of actual custody. Her Honour was also right to take into account Elliott's time in custody in reducing both the head sentence and parole eligibility. I am persuaded however that her Honour erred in not taking into account sufficiently the following mitigating factors in the applicant's case. Her criminal history was relatively minor. Although she had an entry for assault occasioning bodily harm committed in December 2002, the penalty, a $350 fine without conviction, does not suggest this was a serious matter. Whilst the applicant was not a first offender, the judge seems to have placed undue weight on her criminal history whilst wrongly treating Elliott as having no history of violence. Unlike Elliott, she was not on probation at the time of the offences. The applicant was the physical perpetrator of the offences and inflicted actual violence on the complainants. That is an aggravating feature. She was, however, barely 20 years old when she committed the offences and her judgment was affected by alcohol and drugs. Importantly, she has since made promising efforts at rehabilitation, abstained from alcohol and drugs, shown remorse and insight into her conduct, cared for her young children, rebuilt her relationship with her mother and begun to come to terms with her past sexual and physical abuse. She seems at last to be taking responsibility for her past wrong actions and choices. According to Ms Podolak, she seems committed to maintaining permanent care of her children. This Court's decision in R v Horne,[2] a case to which her Honour unfortunately was not referred, makes clear that youthful offenders with limited criminal histories and promising prospects of rehabilitation who have pleaded guilty and cooperated with the administration of justice, even where they have committed serious offences like these, should receive more leniency from courts than would otherwise be appropriate. That is because rehabilitation of young offenders is in the community interest and especially so where the offender is the carer of young children.
