Senator WATT (Queensland—Minister for the Environment and Water) (14:43): Thanks, Senator Whitten. I'm not sure I have that level of detail with me, but I'll certainly seek some guidance on that from the minister's office if we are in a position to provide you with that detail. I'm also not sure that it is correct that that data is not published, so I'll clarify that point as well. If there's any ability for me to come back to you over the course of question time with that information, I'll certainly do so. The PRESIDENT: Senator Whitten, first supplementary?
