Senator WATERS (Queensland—Co-Deputy Leader of the Australian Greens) (14:24): Mr President, I ask a further supplementary question. It is an unfortunate government indeed. I note that Minister Dutton has now belatedly given an apology, although a qualified one. But Minister Dutton's sick joke about our neighbours' losing their homes— Senator Ian Macdonald: Do you have a question? The PRESIDENT: Senator Macdonald! Senator WATERS: is just the latest in a long line of unacceptable behaviour and decisions. The immigration minister has presided over the detention and sexual assault of asylum seekers, spying on members of parliament and now laughing at climate change. When will Minister Dutton be dumped?
