A form of voluntary workplace engagement, communities of practice are characterised in literature as providing entities with the potential to harness the multiplier effects of collaborative processes by building on informal networks within entities. As knowledge building and sharing institutions it would be reasonable to presume that communities of practice activities have been embraced to facilitate a level of connectedness and engagement in a university context. However, evidence from the Australian higher education environment suggests that the enlistment of communities of practice processes by universities faces a number of challenges that are peculiar to academe. We suggest that academic knowledge work practices are significantly different from the business/industry related applications of communities of practice and that an understanding of the unique aspects of such practices, together with the impediments posed by a 'corporate university' model, require acknowledgment before the knowledge building and sharing aspects of communities of practice activities in academia can emerge.
