The Western Australian government has embarked on an employment decentralisation agenda aimed at bringing jobs closer to the people and improving urban sustainability in the Perth Metropolitan Region. This study employs density and accessibility measures to evaluate this decentralisation (or rather ‘poly-centralisation’) policy.

In this paper, we focus our discussion on the participatory practices followed in urban planning. In urban planning, participation is conceptualized and practiced within the framework of the ‘efficiency of sustainable planning process’ through a concentrated understanding of communities’ demand and transformation of commitments with stakeholders into planning actions.
