6 A consignment, addressed to Peng and consisting of three wooden crates weighing approximately 100 kilograms each, was intercepted and tested by Australian Customs and Border Protection officers on 25 October 2012. The contents of the crates returned positive results for the presence of methamphetamine. Subsequent analysis revealed the presence of 29,448.3 grams of a crystalline substance containing methamphetamine, with a purity of 78.6 per cent. The total quantity of pure methamphetamine was therefore 23,154.2 grams. The Criminal Code defines a commercial quantity of methamphetamine as 0.75 kilograms. At the plea, the Court was informed that the value of the drug seized was in the range of $8,232,000 to $9,702,000, with a street value calculated to be in the range of $14,744,150 to $29,488,300.
