To wrap this up in one go here, I'll also ask the Minister not just about the "who" but about the "what", which we get in new section 35DB, in clause 10—the functions of the service provider. I'm particularly interested in not just the information and harm reduction advice, which I've already touched on, but also this question of the outcome of the testing, and when the testers will return or dispose, and what advice they will be giving around that, and any sense he can give us of what that guidance will be from the director-general—if there's anything in this bill, or if he envisages any further regulatory instrument to do that.
