9 In this case the sentencing Judge was prepared to accept that the applicant's role was that of a courier for reward, the reward being the payment of $5000 and the applicant's expenses, and that he delivered "a bulk quantity" of the prohibited drug. He was also prepared to accept that the $39,950 in cash found in the applicant's possession might have been the proceeds, collected by the applicant, of an earlier drug transaction in respect of which the applicant had otherwise played no part. On the findings made by the sentencing Judge, it is plain that, even if the applicant did not know what was the purity of the methylamphetamine in his possession, he undoubtedly knew that he was dealing in a very large quantity of the drug at a "wholesale" level. Moreover, if it be assumed, as the sentencing Judge was prepared to assume, that the sum of $39,950 found in the applicant's possession was not from his own sale of drugs, his receipt of that sum must have reinforced his knowledge that those on whose behalf he was acting engaged in large "wholesale" transactions, involving considerable sums of money. It must consequently have been apparent to him that the large quantity of drugs in his possession might, at least, be of a high level of purity.
