Hon JAMES SHAW (Minister of Climate Change): I'll take those issues raised by Simon Court and Stuart Smith together. They all fall outside of the scope of this bill, because this really is just to do with a mechanism inside the auctioning system, and it doesn't preclude any future decision about the use of international units or the way that those might come into the system at all, because really this bill just deals with that very small matter of the confidential reserve price in the auctioning system. And so, in relation to this bill, no, I have not taken any advice on international offsets.
