the finding that the offence was in the mid range of objective seriousness:
19 Senior counsel for the respondent answered this by challenging the finding that the offence did in fact fall within the mid range of objective seriousness of offences against s66A. The principal basis for the challenge was that, as his Honour expressly recognised, many, if not most, offences against s66A are committed in the context of a history of sexual abuse and of multiple and various offences committed against the same victim. An offence against s66A in the mid range of objective seriousness would be one that was committed as part of a pattern or history of such abuse. Having recognised that such a history is a typical feature of s66A offences, his Honour nevertheless considered that "not helpful" in determining what might constitute an offence in the mid range of objective seriousness. Senior counsel for the respondent contended that this indicated that his Honour regarded the absence of a history of abuse as irrelevant to the evaluation of the objective seriousness of the offence, and that this was erroneous.
20 Care must be taken, in accordance with Way ([101] - [102]) to avoid characterising a typical or common instance of the offence as necessarily one that falls within the mid range of objective seriousness. However, it is correct that the experience of the courts shows, as his Honour mentioned, that repetitive abuse is frequently associated with s66A offences. While a pattern of behaviour is not determinative of the evaluation, that a particular offence is an isolated instance is not irrelevant to that evaluation. I accept that his Honour treated it as irrelevant, and that that was an error.
21 Another criticism made of the reasoning process which led the sentencing judge to conclude that the offence was one of mid range gravity was that his Honour regarded as irrelevant the precise nature of the sexual intercourse. His Honour said:
"I do not think it is appropriate to go into the relative seriousness of whether sexual intercourse takes place by way of oral sex, anal sex or vaginal sex. It seems to me that each of those ways of offending against a young person is equally as bad and to try and suggest that one type of intercourse is less deserving of condemnation than another is I think to really split hairs where it is inappropriate to do so."
22 Senior counsel for the respondent referred this Court to the decision of the High Court in Ibbs v The Queen (1987) 163 CLR 447. The Court wrote:
"The inclusion of several categories of sexual penetration within the offence described as sexual assault carries no implication that each category of sexual penetration is as heinous as another if done without consent. When an offence is defined to include any of several categories of conduct, the heinousness of the conduct in a particular case depends not on the statute defining the offence but on the facts of the case. In a case of sexual assault, a sentencing judge has to consider where the facts of the particular case lie in a spectrum at one end of which lies the worst type of sexual assault perpetrated by any act which constitutes sexual penetration as defined."
23 In R v Davis [1999] NSWCCA 15 Wood CJ at CL wrote:
"[66] In Ibbs v The Queen ... the High Court rejected the proposition that each kind of sexual penetration as defined in the section, there under consideration, was to be regarded as neither more nor less heinous than another. The Court said that such a proposition cannot be accepted. It appears to me that any other view would beggar common sense, and that penile/vaginal penetration of a child is significantly more serious than many of the other forms of conduct encompassed within s66A ..."
24 It might be true, as senior counsel suggested, that penile/vaginal intercourse would, in the circumstances, have amounted to a more serious offence. But does that avail the respondent? Let it be supposed that his Honour had not excluded as irrelevant the nature of the sexual activity in question. It is difficult to think that that of itself would have led him to the conclusion that the offence was of something less than mid range gravity. It is not possible to create some kind of hierarchy of the seriousness of the various kinds of sexual intercourse contemplated by s66A (and defined in s61H). It is the facts and circumstances of each case, including the nature of the intercourse, that enables the proper evaluation of objective seriousness. While penile/vaginal penetration might be taken to be more serious than enforced fellatio, that does not mean that enforced fellatio necessarily falls somewhere below the mid point of objective seriousness. There are many instances of conduct that come within the definition of sexual intercourse that would be significantly less serious than enforced fellatio. Had his Honour considered the nature of the sexual intercourse as relevant, he must, in my view, have come to the view that enforced fellatio falls somewhere in the middle, or towards the upper end, of that scale.
25 Other appropriate areas of inquiry in the consideration of the objective seriousness of a s66A offence are, for example, how the offences took place, over what period of time, with what degree of force or coercion, the use of threats or pressure before or after the offence to ensure the victim's compliance with the demands made, and subsequent silence, and any immediately apparent effect on the victim. Although the sentencing judge was fully conversant with the facts of the offences, he has not explicitly considered these matters in the specific context of the evaluation of objective seriousness.
26 Here, the respondent was not alleged to have used threats or pressure to secure the complainant's compliance, nor to ensure her subsequent silence: there was little if any force or coercion - it seems the respondent relied upon his natural authority as a person in charge of the complainant and her compliance resulted from her acceptance of that authority. The respondent did, however, tell the complainant that she could extricate herself from the trouble she was in for her rowdy behaviour by complying with his demands; and he abused a position of both trust and authority (taking these matters into account does not contravene the principle in The Queen v De Simoni [1981] HCA 31; 147 CLR 383 because there is no aggravated form of the offence which would be constituted by either of those circumstances.)
27 I have come to the view that there was error in the approach taken by the sentencing judge to the evaluation of the objective seriousness of the offence. Error in the approach does not carry with it the necessary implication that the conclusion was erroneous; it means that this Court must make its own evaluation. Having regard to the matters to which I have referred in paras [25] and [26], I have come to the view that the respondent's challenge to the finding that the respondent's offence fell in the mid range has been made good. It should properly be seen as falling somewhere below the mid range of an offence against s66A. Of most significance in this conclusion is that this was an isolated incident. That is, of itself sufficient to warrant departure from the standard non-parole period.
28 That does not mean, as I have earlier pointed out, that the standard non-parole period is of no relevance, and I will return to this.
