Senator WATERS (Queensland—Co-Deputy Leader of the Australian Greens) (14:44): Mr President, I ask a further supplementary question. Today is the 79th anniversary of the extinction of the Tasmanian tiger, which each year is commemorated as Threatened Species Day. Senator Ian Macdonald: Do you have a question? The PRESIDENT: Order on my right! Senator Ian Macdonald: This is question time! The PRESIDENT: Order! Senator Macdonald! Senator WATERS: Mr President, can I ask you to bring Senator Macdonald to order. He is just painful. Honourable senators interjecting— The PRESIDENT: Order! Senator Waters, you have the call. Senator WATERS: Australia has the worst mammalian extinction rate on the planet— Senator Ian Macdonald: Do you have a question? The PRESIDENT: Senator Macdonald! Senator WATERS: and yet the environment minister just forgot about two crucial threatened species conservation advices in his haste to approve the Adani Carmichael coal mine. How many more coal mines, destroying habitat and worsening global warming, will this government bend over backwards to approve? The PRESIDENT: Order! Before I call the minister: Senator Waters, that question bordered on not being supplementary to the primary question, but I will allow the minister to answer the portion of that question he deems fit to answer.
