This study examines the spatial concentration of outlaw motorcycle gang (OMCG) incidents in Melbourne, Australia. The aim of this paper is to explore how OMCG incidents cluster and to identify the neighbourhood-specific characteristics and crime attractors that are associated with the presence of such incidents. We compare the clustering of OMCG incidents with several other non-OMCG crimes to investigate whether OMCG incidents are likely to occur in areas where there is a broader history of criminogenic activity. The results indicate that disadvantage and residential instability are statistically significant for both OMCG and non-OMCG crime incidents. Ethnic diversity was only significant for non-OMCG crime incidents. Interestingly, crime attractors, specifically licensed premises and tattoo parlours, increased the prevalence of non-OMCG crime types. The study finds greater support for social disorganisation theory and the concentration of OMCG crime than for the presence of crime attractors and crime generators.
