Senator CORMANN (Western Australia—Minister for Finance and the Public Service, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:37): We make decisions based on science and objective evidence, not politics. We have a responsibility to follow proper process and we will continue to follow proper process in relation to this important project. I can also advise the Senate that Adani still needs to provide further information in relation to aspects of the plans before they can be approved and, as I've already indicated, expert advice is being sought from Geoscience Australia and the CSIRO on the groundwater plans to ensure that water resources are properly protected. The PRESIDENT: Senator Waters, a final supplementary question.
