The South Australia Police Operation Mandrake highlighted the very significant issue of serious repeat offending by a small number of young people. This report considers serious youth repeat offending in general; not just the young people upon whom Operation Mandrake is focusing, and not just offending by Aboriginal young people. It is important to note that although South Australian research into serious repeat youth offending reveals that young Aboriginal offenders are over-represented in this group, the majority of serious repeat offenders are non-Aboriginal. Accordingly, most sections of the report begin with a focus on issues under consideration as they relate to youth justice in general, then move to a discussion of serious repeat offending by young people, and then make specific comments about how these issues relate to Aboriginal young people. The report begins with a brief outline of the consultation process. Drawing together all of the information gathered, the report discusses the experience of: young people who have become involved in serious repeat offending; victims of youth offending; and Aboriginal people in particular. A set of very specific recommendations conclude the report. Statistical data and research findings are included in separate boxes at relevant points throughout. As such, the report provides a current picture of the youth justice system in South Australia. There are areas of very good practice; however, there are also some gaps in how services respond to these young people and their families. This report seeks to address those gaps by presenting strategies and recommendations for further action.
