In your case, there is no doubt that with your source in South Africa, you were close to the sources of the drug, particularly so far as its distribution in Australia is concerned. In my view, you must have known of the quantity and purity as you were the importer.
I'm not in a position to determine further on the facts your role in the distribution chain, other than you sourced the drugs from South Africa, and upon receiving them from the undercover officer, were to give them to Mr [Haddad]. On that basis, on your case, your role in the distribution comes to an end.
Nevertheless, given your role in bringing these drugs into the country and given the sheer quantity and the purity and the widespread consequences of distribution when it was to occur, your culpability is high. You were a very important and substantial link in the chain of distribution.
Having said this, I'm not in a position to make any finding against you as to the extent of your commercial involvement. According to you, you only did this transaction in order to secure the job in the jewellery business. I'm not satisfied that that is, in fact, the case but can take the matter no further than that.
