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.
