Although Italian mafia scholars have recently been turning their attention to the Calabrian mafia (known as the ’Ndrangheta) diaspora in Australia, their efforts have been limited by conducting research remotely from Italy without the benefit of local knowledge. Australian journalists and crime writers have long played an important role in documenting ’Ndrangheta activities, but have in turn been limited by a lack of expertise in Italian language and culture, and knowledge of the Italian scholarly literature. As previously in the US, Australian scholarly discussion of the phenomenon has been inhibited, especially since the 1970s, by a ‘liberal progressive’ ‘negationist’ discourse, which has led to a virtual silence within the local scholarly literature. This paper seeks to break this silence by bringing the Italian scholarly and Australian journalistic and archival sources into dialogue, and summarising the clear evidence for the presence in Australia since the early 1920s of criminal actors associated with a well-organised criminal secret society structured along lines familiar from the literature on the ’Ndrangheta.
