14 Because of the nature and degree of co-operation which the applicant provided, it was submitted that the applicant should have received a much more substantial discount from the sentence that would otherwise have been appropriate. In particular, it was submitted that it was not her fault that the delivery which was attempted in Adelaide was not effected and that no one was arrested at the end of the day. Her actions in co-operating exposed her, and could in the future continue to expose her, it was submitted, to the risk of repercussions. Hence, there was every justification, it is said, for there to be a real and genuine incentive reflected in the sentence for this type of co-operation. In particular, it was submitted that the observations of his Honour, quoted above, indicate that the discount which his Honour did allow was less than might otherwise have been the case because the attempt to delivery in Adelaide failed. It was submitted this was an erroneous approach in principle and that the determinative factor should be the nature and degree of the co-operation provided and the risk to which the applicant was exposed as a consequence.
