Senator WATERS (Queensland—Co-Deputy Leader of the Australian Greens) (14:38): Mr President, I ask a supplementary question. Sir David Attenborough says that the Great Barrier Reef is in grave danger from climate change. One of Australia's foremost coral reef scientists, Professor Terry Hughes, says that we have to choose between new coal and the reef—that we cannot have both. What do you and the Prime Minister say to the 69,000 people whose jobs rely on the reef remaining healthy, when you keep approving coalmine after coalmine after coalmine?
