43 It follows from the allowance of the appeal on grounds 1, 3 and 4 that, in my view, the sentence imposed was manifestly excessive and must be reviewed. However, for an offence of this kind, for the reasons given in Nawrojee (supra), the starting point must be a sentence of imprisonment. It then becomes necessary, having regard to the decided cases and my earlier observations, to give proper weight to the appellant's personal circumstances including her age, the absence of any prior convictions, and her plea of guilty which must be regarded as facilitating the course of justice, and given some weight accordingly. I accept that her maintenance of a plea of not guilty was partly referable to legal advice and the entitlement of a litigant to put up a not guilty plea as part of the trial process. I give some weight also to the proposition counsel for the appellant extracted from McKenna v The Queen (1992) 7 WAR 455 at 468 (Seaman J) that youth is a significant mitigatory factor (although normally its weight decreases as the offender moves through the early 20s) and so is the need to attempt rehabilitation of youthful offenders. In this case, the appellant was only 21 years of age at the time of the offence and had no prior convictions. The personal references submitted to the Court speak well of the appellant.
