While attention to the 'ndrangheta, the Calabrian mafia, in Australia, has significantly increased in the past two decades, historical records referring to this peculiar manifestation of organised crime in the country date back almost a century. This research is situated in between studies on mafia mobility and studies on the nature of mafia-type organised crime in Italy and in Australia. Relying on archival research, fieldwork and focus groups with law enforcement agencies across most Australian jurisdictions, this paper will essentially argue that there is in Australia an ongoing criminal system that is made of ethnically hybrid criminal networks-predominantly made of, but not limited to, Calabrian ethnicity. Ethnic solidarity and traditional norms and values of the 'ndrangheta, embedded in Calabrian migrant culture, provide the roof to these networks' behaviours and organisation. This paper will discuss how the resilience of this mafia in Australia is linked to the capacity of 'ndrangheta clans to maintain different heads-to be polycephalous-all differently and equally important: their organisational head is stable and culturally homogeneous, their (mafia-type) behaviours are constant, flexible and rooted in ethnic solidarity, and their activities are very dynamic, but hybrid in their ethnic composition. Introduction and methods The 'ndrangheta is today considered the 'most powerful' Italian mafia, with specific reference to its penetration in Italian society as well as its international presence, especially in the drug trade (Sergi and Lavorgna, 2016). According to the Italian National Antimafia Prosecutor Directorate (DNA, 2017: 3), recent investigations "confirm the diffused presence of the 'ndrangheta in almost all Italian regions, as well as in different countries, not just in Europe, but also in America-United States and Canada-and in Australia". As any other mafia group (Sergi, 2017b), the 'ndrangheta clans are characterised by the commission of criminal activities for profits as well as the quest for power, political and financial. Building on previous studies on the topic (Sergi, 2015; Bennetts, 2016; Spagnolo, 2010), this study will present the results of two months fieldwork in Australia between July and August 2017-and the accompanying desk research.
