30 Let me deal now with a specific issue. Count 5 on the indictment is, as I have said, an offence of aiding and abetting an aggravated sexual assault. I was told that that carried with it a standard non-parole period of ten years. I confess to having some doubts as to whether that is the case. The offence is described in the table to s 54D of the Crimes (Sentencing Procedure) Act as aggravated sexual assault. That may be a shorthand expression intended to cover aiding and abetting an aggravated sexual assault. However, I do note that it was the crown submission and Mr Hancock accepted, that the standard non-parole period would apply to an offence of aiding and abetting an aggravated sexual assault. However, of course, in this case the standard non-parole period is not of direct application because Mr McGaw pleaded guilty to count 5 on the indictment. The standard non-parole period nevertheless remains as a guide post to the appropriate non-parole period in the present case. Although the offence itself was an offence which I am satisfied was above the middle range in its objective gravity, the fact that the offender was an aider and abetter rather than a principal means that the objective gravity of the offender's conduct was below the middle range of objective criminality of offences covered by the standard non-parole period. The offences are aggravated by the circumstance that they involve gratuitous cruelty. That includes those threats to DS in which he was told that he would be killed. They also include the way in which the sexual assault, the subject of count 5 was carried out. Although the penetration of DS's anus with an object is an element of the offence, and thus it would be wrong for me to take that into account as a circumstance of aggravation, the particular manner in which the rolling pin was used, is such that I am satisfied that it did involve gratuitous cruelty and the particular manner of its use does thus amount to an aggravating circumstance which I will take into account.
