31. That there were two offences enlarged the range of sentencing options available to her Honour. She could have, as an alternative, suspended the sentence for one or other of the offences and/or considered partial suspension of the other. The result would have been that the appellant would have tasted an adult prison for the first time and experienced the contrast between it and the child welfare institution she had previously known. She could have then been released and, significantly, released with the knowledge that she would be returned to prison for a longer period if she offended again.
32. The principle of parsimony or minimality is especially important in relation to youthful offenders, where, as we have indicated, rehabilitation of the offender is almost always a matter to be given great importance. The present case is not simply one of an offender who has been given many chances and failed to take advantage of them. Rather, the appellant was young and apparently immature for her age at the time of committing these offences. Despite the aggravating features, these offences cannot be classed as, comparatively, really serious. While the appellant's prospects for rehabilitation did not appear bright, there was some indication that she had shown a dawning preparedness to moderate her untoward behaviour. In short, she was not beyond 'rational hope' of rehabilitation cf R v Blaskovic [1999] FCA 1306 at [31]. Positive remarks in the pre-sentence report lent support to that view.
33. It seems to us that, had the learned Magistrate had present to her mind this principle and its proper application to the present case, she could not have imposed the sentence that she did, at least without explanation of why the precise course she was choosing was necessary. No such explanation was apparent or is otherwise obvious. We conclude that her Honour did not apply what we have referred to as the principle of minimality, as she should have done.
34. Likewise, although the point was raised only in the course of the oral submissions before us, technically and sufficiently it was an appellable error by the learned primary Judge not to have corrected the Magistrate. The point is of general importance, could not be cured by the respondent's calling of further evidence and concerns the propriety of a first custodial sentence for a young offender to be served in an adult gaol. Exceptionally, we would allow the point to be raised.
35. The consequence is that the appeal should be allowed and we should re-sentence the appellant.
