Abstract: Community participation in planning is generally considered crucial for the delivery of positive outcomes; however, the network structure that can be created by a community group using social media and who participates in the network are not widely understood. This paper explores the use of social media, specifically Twitter, by two community groups. In the context of this study, community groups are self-created and organised groups of citizens that form to oppose a proposal to amend planning controls for a specific site. Utilising the research technique of Social Network Analysis (SNA), this paper seeks to visualise the community group networks, as well as understand the connectedness and clustering of the networks. For the two community groups investigated, it was found that they do not attract large numbers of friends and followers on Twitter and key stakeholders play a passive listening role in the networks.
