Abstract: Historically social housing has acted as a catalyst for community concern, resistance and activism (Bostock et al., 2004; Rose, 2004; Kleinman, 1999). Such resistance is couched in concerns over the changing nature of place and the character of local neighbourhoods and anxiety over social issues such as crime and stigmatisation (Jacobs et al., 2011; Arthurson, 2004; Randolph and Wood, 2004). However with the Australian context, under a neoliberal urban governance model, such conflict and community concern has been tempered as very few new social housing dwellings have been constructed (Jacobs et al., 2010; Beer et al., 2007). The purpose of this paper is to neither provide a comprehensive review of academic writings on social mix nor to provide a detailed discussion of such policies in Australia, as this is done elsewhere (Randolph and Wood, 2004; Musterd and Andersson, 2005; Galster, 2007; Graham et al., 2009). Rather, while providing an overview of the perceived benefits of such polices at a broad level, here social mix is repositioned as a discursive construct which, at least in the context of the Nation Building Economic Stimulus Plan (NBESP), has been adopted by local residents as a tool for challenging the legitimacy of new developments. Social mix therefore moves from a policy objective (however loosely) associated with the management of social housing, to a discourse used to challenge the very process of providing social housing. This paper offers a unique opportunity to explore the ways in which social housing and notions of social mix are constructed by communities prior to new social tenants moving in. As such, this paper does not explore the actual interaction of public and private tenants, but rather focuses on the ways in which constructions of policy, community and social housing are mobilised to challenged the legitimacy of new social housing constructed under the NBESP.
