18 In the instant case, there was no assessment undertaken of the objective gravity of the offences, insofar as no attempt was made to determine where on the scale of criminality these examples of the offences lay, referable to the maximum penalty prescribed by the legislature in each case. Accordingly, the respondent's criminal history, subjective circumstances and prospects of rehabilitation could not be meaningfully measured against the respondent's objective criminality. I do not mean to suggest by these remarks that it is necessary to undertake a mathematical or prescriptive approach to sentencing, or that one should engage in a two-tier approach : see Markarian v The Queen [2005] HCA 25. However, his Honour's remarks lacked the transparency that would allow the respondent, this Court and the general community to understand how it was that his Honour arrived at the final result."
51 In relation to the s 66A offences, the Judge made a finding that they did not fall within the mid-range of objective gravity, but he said no more than that. It was open to him to make that finding, given that the offences were constituted by fellatio. But the extent of the influence of the standard non parole period on the non parole period imposed for each of these offences very much depended upon whether the offences were just below, moderately below, or well below the mid-range of objective gravity.
52 The reasons given for the Judge's finding in relation to the s 66A offence are set out in para 57 of his Remarks on Sentence (quoted in para [29] above). Apart from the reference to fellatio, the reasons refer to the absence of certain aggravating features in the offending behaviour. In other words, the absence of aggravating features in relation to these offences is said to justify a downward revision in the assessment of objective gravity. The logical extension of this proposition is that the greater the number of aggravating features missing from the commission of a child sexual assault offence, the lower will be its objective criminality. This is problematic, to say the least.
53 Offences relating to sexual activity between young children and adults are premised upon the vulnerability, dependency and immaturity of children. It is those attributes that render young children amenable to sexual exploitation by adults. The structure of the offences, and the legislative policies underpinning them, assume that young children are not capable, by and large, of understanding the significance of sexual activity (hence the absence of informed consent) or of asserting their will over that of an adult. How then, can the fact that a victim co-operates with an offender be relevant to an assessment of the objective gravity of an offence of this type? That is not to say that evidence of a victim's resistance and/or an offender's efforts to restrain a victim are not relevant to an assessment of objective gravity for offences of this type. Such a circumstance would aggravate a child sexual assault offence. But the absence of struggle or resistance (that is, the child's co-operation) cannot, in our view, mitigate such an offence.
54 In the present case, we assess all of the s 66A offences as moderately below the mid range of objective gravity. The three offences against ME were committed when the victim was eight years old, a significant factor in the assessment of objective gravity : MLP v R [2006] NSWCCA 271 ; 164 A Crim R 93. One of them (sequence no. 3) was committed in the presence of another child. The offence against NB (who was just under ten years of age) was committed while the respondent and the victim were watching a pornographic video and when the respondent occupied a position of trust towards him. In addition, it must be borne in mind that these offences were part of a pattern of conduct on the respondent's part, which displayed "grooming" characteristics.
55 As for the remaining offences, sequence nos. 1, 4, 7, 9, 10, 15 and 22 were constituted by fellatio and were all aggravated, either by a breach of a position of trust or by commission in the presence of another child. In our view, they also fall below the mid-range to a moderate degree. The two offences of attempt anal intercourse (sequence nos. 2 and 8) were committed in breach of a position of trust. The respondent only ceased his attempt at penetration when the victim told him it was painful. We would categorise these two offences as just below the mid-range. The offences constituted by acts of masturbation (sequence nos. 11, 13, 24, and 26) were all dealt with as summary offences, as were two of the firearms offences.
56 The Judge's assessment of the criminality inherent in the offence of Possess Unauthorised Firearm was generous to the respondent. The Judge found that the respondent's possession on 16 January 2007 "was more about securing the weapon and delivering it to police." However, this overlooks the fact that the police had interviewed the victim NB on that day and the boy had provided details of the respondent's habit of keeping the gun in a cupboard or under the bed. The charge may have been referable to 16 January but it was not correct to limit the respondent's possession to merely transporting the gun to police. This offence should have attracted a more significant penalty than imposed by the Judge.
