Senator SIEWERT (Western Australia—Australian Greens Whip) (15:54): Mr Deputy President, I seek leave to make a short statement. The DEPUTY PRESIDENT: Leave is granted for one minute. Senator SIEWERT: As I am sure the coalition generally does know, there was an extensive amount of consultation carried out on the world-leading biodiversity marine protected area system that was in place until about two months after the Abbott government came to power, when it effectively got rid of our marine reserves by suspending the management plans. The news that came out just at the end of last week that 38 per cent of the world's coral reefs will be subject to coral bleaching, of which five to 10 per cent will be permanently dead, highlights yet again the importance of making sure that we have the world's best marine protected system to give our coral reefs the best chance they can have to survive climate change. The DEPUTY PRESIDENT: Thank you, Senator Siewert. Again, I remind senators that statements by leave to motions during discovery of formal business should not amount to a de facto debate on the motion. The question is that general business notice of motion No. 879 be agreed to. Question agreed to.
