[14] True it is that, critical to the assessment of the criminality of an offender who is to be sentenced in an illegal drug network is finding the offender's role and level of criminality. In determining the appropriate sentence, this may be a more important factor than the quantity of drugs involved: Melikian v The Queen.[3] Courts have long recognised, for example, that low level couriers generally receive a lesser sentence than those at a higher level in the drug hierarchy: Tyler v The Queen.[4] The judge was not asked by any party to make any particular factual findings at sentence. All the findings made by the judge were well open on the evidence, including the finding that Burling was involved with Dehghani in the dispatch of the drugs. It is clear from his Honour's sentencing remarks that he was entirely familiar with the role played by each of Dehghani, Burling and Gill in this importation. Although the roles of Burling and Gill were less than Dehghani's role, his co-operation with the authorities was, at least at the time of his sentence, considerable. Both Burling and Gill played significant roles in the importation. Gill's role, although less than Dehghani and Burling's, was vital to the success of the importation. The primary judge's sentences recognised the different roles of all three offenders. His Honour did not sentence either applicant on any incorrect factual or legal basis.
