  • The perpetrator of the 2014 Sydney Lindt Café siege had been charged with organising the murder of his ex-wife and had a documented history of violence against other women.
  • The Fixated Grievance Perpetrator Intervention Pilot brings together experts in forensic psychology and psychiatry, criminology, policing, perpetrator intervention and victim support.
  • With $21.8 million funding from the federal government, the pilot will be rolled out in two different states and evaluated by the Australian Institute of Criminology.
