National Action on Affordable Housing in Australia reflects new and more inclusive ways of thinking about and responding to the housing affordability needs of low and middle income Australians. National Action on Affordable housing extends responsibility for addressing housing affordability beyond the existing current social housing sector to planning and local government, the private and not for profits sectors as well as a number of other government portfolios. This way of conceptualising affordable housing responses is significantly different to existing Commonwealth State Housing Agreement responses to affordability. Consequently, in order to affect change as envisaged by National Action on Affordable Housing, new ways of organising and collaborating – new ways of governing – will be required. This discussion paper explores some governance options that could facilitate National Action on Affordable Housing.
