Senator PATRICK (South Australia) (15:49): I seek leave to make a short statement. The DEPUTY PRESIDENT: Yes. Senator PATRICK: One of the things I like about the Murray-Darling is it does turn the Senate into the states' house and we see all the different perspectives and that's very rare. But the fact of the matter is that there was an agreement to the plan and, that included the 450 gigalitres, so you can't walk back from that now. That is an important element. It was something that South Australia negotiated before it ceded powers to the Commonwealth in relation to this, and it can't be rescinded. We need to support the plan in full. The DEPUTY PRESIDENT: Senator Patrick, I do appreciate we are in a division, but it is appropriate that you speak from your seat. Opposition senators interjecting— The DEPUTY PRESIDENT: He is? I beg your pardon, my error. Sorry.
