Senator McKENZIE (Victoria—Minister for Rural Health, Minister for Sport, Minister for Regional Communications and Deputy Leader of The Nationals) (14:39): Thank you, Senator Leyonhjelm, but I don't actually accept the premise of your question. Goods and services across the economy that have a wide range of health and maternal benefits for both infant and mother attract the GST, from which the states and territories can fund positive policies and initiatives that target infant and maternal health. As the senator will be aware, matters relating to changing the GST would require the unanimous support of all states and territories. Likewise, the operation and any future changes to the GST are a matter for the Treasury portfolio colleagues in cabinet. In that respect, I would refer them to Senator Cormann. The PRESIDENT: Senator Leyonhjelm, a final supplementary question.
