The issue of violence in Indigenous communities has attracted serious and increasing political and media attention in recent years, the culmination of which is represented by the Northern Territory Emergency Response and the Violence and Child Abuse Intelligence Task Force. This report focuses on the Indigenous perpetrators of this violence with the aim of providing quantifiable and empirical evidence on risk factors, prevalence and nature of violent behaviours. The first section of the paper deals with conceptual issues and key definitions and includes an overview of the ecological systems approach to research adopted by the study, before summarising some general criminological theories to help in later explanations. The second section presents statistics on the nature and frequency of discussed violence, drawing comparisons with non-Indigenous offenders and offering a description of victims and the relationship of victims to the offender. The report then goes on to illuminate the cultural, historical, community, individual and familial risk factors to violence before offering conclusions and suggestions for better addressing gaps in the research and data collection on information relating to Indigenous violent offenders and case histories.
