This study estimates the taxpayer savings from cancelling or refusing the visas of organised crime offenders. Using data from the Australian Criminal Intelligence Commission and the Department of Home Affairs, the research produced a statistical model of the known lifetime offending by organised crime offenders in Australia and applied this to the 184 organised crime offenders whose visas were cancelled / refused between December 2014 and May 2018. The results show organised crime offenders are a prolific group. They show a level of activity, and persistence in offending, unlikely to be observed in any general population of offenders. Offending by outlaw motorcycle gang (OMCG) members is more serious than other organised crime offenders. Cancelling or refusing the visas of 184 organised crime offenders (139 of whom were OMCG members) is estimated to save the community $116 million as a result of the crimes prevented and savings to the prison system.
