Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:43): Yes. I am aware, as I think all Australians are, of the floods which occurred in the period to which you refer and of the effect on river communities, including in South Australia—as Senator Ruston would attest to—as a consequence of those floods. What I would also say is that I also, like many other South Australians, would go down to near the Murray mouth, and there was a lot of water coming through, a lot of pollution, obviously, and a lot of topsoil. It was a really difficult time, I think, for people both downstream and upstream, as a consequence of those floods. I think Senator Watt will be able to speak more broadly about the flood response from the Commonwealth government. Certainly, it was a very difficult time for many communities. However, that doesn't obviate the policy point, which is we know the Murray-Darling Basin Plan hasn't been delivered by those opposite. And we know that, over 10 years, the divisions which are now on display in the coalition, as between the National Party and some parts of the Liberal Party, particularly those from South Australia, meant that that plan was not delivered. We now have those opposite intent on wrecking a plan that they undermined whilst in government; that is the hard reality. What I also would say— Opposition senators interjecting— Senator WONG: It's so predictable, isn't it? What I would also say to you, Senator Van, is the fact that there was a lot of water as a consequence of flooding does not obviate the broader policy problem, which is how do we deal with over-allocation and sustainability, environmental flows as well as economic sustainability. All of these matters are matters the government has seized on. (Time expired) The PRESIDENT: Senator Van, a first supplementary?
