Outlaw motorcycle gangs (OMCGs) are often reported to be disproportionately involved in crime. Debate continues about the relationship between the organisational structure of these groups and the extent and types of criminal activities undertaken by group members. A systematic review of the existing literature was conducted to examine the organisational structures that underpin the criminal activity of OMCGs. The available empirical research, though scant, supports the notion that, at least in some clubs or chapters, the structure of OMCGs facilitates criminal activities by individuals or small cliques, sometimes in collaboration with non-members.

Using national data on the criminal histories of 5,669 known outlaw motorcycle gang (OMCG) members from 39 gangs, this paper explores the prevalence of violent and organised crime offending among Australian OMCGs. Violent and profit-motivated offending was common among OMCG members. One in four had been apprehended for a recent offence involving violence and intimidation, and one in eight for organised crime-type offences. Offending and associated harm was concentrated among a relatively small group of members. Half of all chapters and three-quarters of gangs had members recently involved in organised crime-type offending. In 11 gangs, both office bearers and other members were involved in organised crime, indicative of their status as criminal organisations. These gangs were also among those with the highest prevalence of violence and intimidation offences.

This study explores changes to the internal culture of a sample of Australian outlaw motorcycle gangs (OMCGs). We analysed data from 39 in-depth interviews with former OMCG members in Queensland to discern changes in recruitment practices, hierarchies and governance processes, as well as values, norms and relationships experienced and observed while members of an OMCG. Structurally, clubs changed little, although participants described how members were increasingly using the structures and systems of clubs for their own benefit. Changes were noted in recruitment practices, which were seen as increasingly geared towards enlisting violent, criminally-inclined men. There was also a perceived erosion of loyalty and camaraderie within OMCGs, with a shift towards younger, newer members who were seen as self-interested and financially motivated. These changes were contributing factors in decisions of many former members to disengage from OMCGs.

This study examines the trends in and spatial distribution of recorded offending by Australian outlaw motorcycle gang (OMCG) affiliates at the onset of a territorial conflict between two clubs in the state of New South Wales. Results show an increase in recorded offending by OMCG affiliates involved in the conflict and based in the disputed territory. Comparable increases in recorded offending by these clubs were not detected in the areas surrounding this territory or in the rest of New South Wales, and there was little mobility into the conflict region by those outside of it. There was a smaller, short-lived increase in recorded crime by affiliates of other gangs in the conflict region but not elsewhere. In short, changes in offending patterns were largely limited to the clubs involved in the conflict and localised to the territory in dispute. This research can help guide focused law enforcement responses during periods of gang conflict.
