"18 It can ... be accepted that the applicant had an important role in the distribution chain, having access, for distribution purposes, to relatively large quantities of high grade heroin. In those circumstances this was a case in which the starting point for the sentencing of the applicant could be expected to be severe. As was pointed out by Kennedy J in Serrette v The Queen [2000] WASCA 405 at [2], it has frequently been said that those who engage in the illicit drug trade, whatever their role in the enterprise, must expect heavy sentences in which general deterrence will be the principal purpose of the punishment. This is especially so where an offender plays an important role in the distribution process.
19 That said, it seems to me that the starting point of 18 years in this case was too high, having regard for what has been said in Quach and in Wong. It is true that the range suggested in Quach is one which applies to couriers (and that is a term which can conceal as much as it reveals: see R v Olbrich [1999] HCA 54; (1999) 199 CLR 270 at 279) and not to distributors. However that range was expressed to apply to those who are close to the source of importation and who commit the offence for commercial gain. It seems to me that there can be little to choose between a worst case 'courier' who has between 600 and 700 grams of heroin with a purity between 55 and 65 per cent, who is well aware of the quantity and quality of heroin in his possession, who actively participates in attempts to conceal it, who commits the offence for commercial gain and who is close to the source of importation, on the one hand, and a person in the position of the applicant in this case, on the other. It also seems to me that a starting point of 18 years is excessive when compared with the range suggested in Wong, even taking into account the absence of remissions in New South Wales and the fact that the range there suggested was intended to apply to 'couriers' and to persons low in the hierarchy of the importing organisation.
20 It consequently seems to me that a starting point of 18 years' imprisonment was outside the appropriate range and that a more appropriate starting point in the case of the applicant, even taking into account that he was a person 'higher up in the distribution chain' than a 'mere courier', was one of 16 years' imprisonment."
