This paper investigates and categorises players in the identity fraud landscape in Australia. The player categories include: government and non-government proof of identity (POI) issuers and users; law agencies; the perpetrator; target organisations; solution providers and experts; the media; and community interest groups. The various interactions and collective arrangements between these organisations within and across sectors are important for several reasons. Firstly, in Australia, participants and identity crime perpetrators usually need a ‘set’ of POI documents which sum to at least 100 points in order to open accounts or receive benefits. The POI gathering sequence is referred to as the ‘circularity effect’ of acquiring POI documents. Secondly, perpetrators attack the ‘weakest link’ across a targeted sector and within targeted organisations. A contribution of this paper is to educe how organisations, in an IS context, through knowledge management (KM), knowledge sharing, sense-making, and organisational learning, from within and across sectors, can collectively combat the identity crime phenomenon.
