Understanding the structure and composition of co-offending networks in Australia


A large volume of criminal offending involves two or more individuals acting collaboratively. In recent years, much contemporary research on group crime has integrated research on co-offending with the study of criminal networks. However, while this research (mostly from the United States and Canada) is generating significant insights into co-offending, there is a notable absence of research on co-offending and co-offending networks in Australia.

This report presents the findings of a study into co-offending using arrest data from Melbourne, Australia. The study sought to extend previous work on co-offending by analysing the range of crime types committed by individuals and co-offenders across co-offending networks.
