This presentation describes an evaluation of a two-year trial of bi-lateral (perpetrator and victim) electronic monitoring of high-risk family violence perpetrators in Tasmania, completed early 2021. The project began in 2018 as a trial and was incorporated in standard business operations mid-2020. Observations of key activities, such as fitting of devices, court proceedings, and multiagency meetings, as well as semi-structured interviews with stakeholders, including perpetrator and victim participants, were conducted throughout this project to assess effectiveness against objectives including increased safety to adults and children subjected to family violence, increased perpetrator accountability, increased conviction rates for family violence and associated offences, and reduced social and justice related costs.

The project was a collaboration between Tasmania Police and Department of Justice. Family violence perpetrators were assessed by the Tasmania Police Family Violence Unit to determine suitability for electronic monitoring and monitored 24-7 by the Department of Justice’s Monitoring and Compliance Unit. The uniqueness of this Tasmanian project is that victims are able to opt-in to a service that allows victims to alert the monitoring unit if the perpetrator approaches them. The presentation will draw on both quantitative and qualitative data, focusing on the process of implementing electronic monitoring in Tasmania, including the experiences of those participating in the program. Electronic monitoring proved a successful tool in holding perpetrators to account and keeping victims safe.
