Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:23): I again hear the interjections from the National Party. We wonder why the coalition never delivered on this. I remember, when I was water minister and I bought a lot of water, how angry they were that we actually bought water for the environment from willing sellers. Oh my goodness! Isn't it dreadful to use the market to deliver an environmental and social outcome! It's a dreadful thing, isn't it? Opposition senators interjecting— The PRESIDENT: Order! I am unable to hear Senator Wong's response. Please remain quiet and show courtesy. Senator WONG: The Minister for the Environment and Water confirmed yesterday she has written to and is speaking to basin water ministers because, obviously, we have to work with the states in order to deliver this. Minister Plibersek has also tasked her department to consult widely on creative and collaborative approaches on how we can deliver the plan in full. I say this: nothing is off the table, including voluntary buybacks, because it is clear that the approach that was taken on the other side did not work. (Time expired) The PRESIDENT: Senator Hanson-Young, second supplementary?
