Senator WILLIAMS (New South Wales—Nationals Whip in the Senate) (14:52): Mr President, I have a supplementary question. If the government is to be believed on its promise to increase Australia's food producing capacity, why won't it give consideration to the construction of dams that can help increase the security of farmers' water supplies? Why does a National Food Plan mention the word 'dams' precisely once and only with regard to aquaculture?
