Senator RUSTON (South Australia—Minister for Families and Social Services and Manager of Government Business in the Senate) (14:49): Thank you very much, Senator Bragg. Drug testing is absolutely a common and consistent feature in Australian businesses all around this country. If you have an issue with drugs, it impacts on your function at work, it impedes your ability to take up a job and it will prevent you from being able to take a job that requires drug testing. Hundreds and hundreds of Australian companies currently require drug testing and alcohol testing of their employees, most particularly because of safety in the work environment—obviously, you can't use machinery; you can't drive a vehicle. Companies like Linfox and Qantas constantly require their employees to undertake drug testing. Many Commonwealth agencies also require drug testing and, at the risk of channelling somebody that I don't particularly want to channel, even the CFMMEU called in 2015 for a blanket drug and alcohol test for worksites right the way across Victoria, and this is commonplace.
