In assessing the extent of your culpability I bear in mind ... that you were caught in possession of a significant quantity of methylamphetamine - 971 grams. The purity of it ranged between 74 per cent and 78 per cent. That indicates that the drug itself was close to the source of supply - close to the source of manufacture.
It also indicates that when it's cut to street level purity, the quantity in question in this case would be considerable. It was a very valuable commodity that you'd been asked to go and collect and deliver.
I am satisfied that even if you did not know what the purity of the methylamphetamine was, and I've mentioned this earlier in my ruling, you undoubtedly knew that you were dealing - you were couriering a very large quantity of drugs at a wholesale level. The very fact that you were doing that for a person to whom you owed over $23,000 must have indicated to you that you were doing a substantial favour for these people; it had to be worth a lot of money.
As I said in my ruling, you knew you were couriering a bulk quantity of drugs under instructions from someone you owed a considerable drug debt to. You appreciated you were couriering a very large quantity of drugs at a wholesale level, given the weight of the drug, which must have been obvious to you the moment you picked it up in that car park. And that you were doing that couriering because you owed [$23,760].
And it would have been obvious to you also that you were trusted by these people to pick up and deliver a wholesale quantity of drugs which could then be cut by others to put a considerable amount of drugs on the street. You were not transporting the drug to support a habit, but as a favour to the person to whom you owed drugs.
I view your offending also, in the context of the drug related incidents on 7 January 2010 and 3 April 2007, which makes your involvement in the drug offending on this occasion, at a higher level of seriousness.
Bear in mind also that you've been entrenched in the drug trafficking subculture for some time during which you've had access to firearms and considerable amounts of cash as a result of drug dealing; 23,760 that we just heard of, the amounts of $20,000 and $48,480 on the earlier occasion (08/10/2010: ts 129 - 130).
