And this is a much-needed intervention to ensure that the market—created by intervention in the first place—continues to work effectively and well. I thank Mr Andrew Bayly for the way he talked about the necessity for this amendment, the necessity for it, because we do need that secondary market to be an effective market. Now, of course, when those auctions go ahead, people bidding in the auctions will have a very good idea of what a reserve price will be set around about—they'll know, they're business people, they will understand it—but we nevertheless still need that confidential reserve price to make it all work in the best way possible. That is exactly what this very, very technical piece of legislation does. On this side of the House we of course support this bill because we know how much we need an effective emissions trading scheme in order to help us to deal with the challenges of climate change. So, Madam Speaker, I commend this bill to the House.
