Senator SIEWERT (Western Australia—Australian Greens Whip) (14:16): My question is to Senator Ruston, the Minister for Families and Social Services. In an article in Tuesday's Sydney Morning Herald, Toby Hall, Chief Executive of St Vincent's Health Australia, wrote, of the government's proposal to drug test income support recipients: There is not one shred of evidence—here or overseas—that shows compulsory drug testing works to help someone on a path to beating their drug problem in the long term. He went on: … this policy would be counter-productive because it stigmatises people. We know stigmatisation is one of the biggest barriers to people asking for help. Any increase in stigma and anxiety for people with substance-use disorders will exacerbate their addiction rather than help them. Despite unanimous opposition from the health and addiction sector, the government once again has introduced legislation to drug-test income support recipients. Minister, what makes the government think they know better than the experts; and why in Australia would it be any different from overseas failed experiences of drug testing?
