Senator McKENZIE (Victoria—Minister for Agriculture and Leader of The Nationals in the Senate) (14:31): I also, as one of the few people in this place with a science degree, like to base my policy decisions on science and data. It is very difficult to make key decisions on policy without accessing stringent data, and that's why our government has initiated a range of measures to strengthen compliance and enforcement, including $35 million to expand metering and satellite remote-sensing technology in the northern basin, $25 million to encourage the installation of meters by irrigators in the northern basin as part of a comprehensive package of measures regarding the fish death reports and $5 million for cameras to capture livestream river flows to provide transparency to the public. We're taking our role very seriously. It is also up to state governments—New South Wales, Victoria and South Australia—to support their farmers to measure the flows accurately. The PRESIDENT: Senator Roberts, a final supplementary question.
