According to recent international research, political mobilisation at the local level no longer reflects socioeconomic divisions in society, but is instead based on a post-material oriented â€˜politics of choiceâ€™. This proposition is applied to group politics within six Sydney communities. We broaden the examination of political activity undertaken by local groups to include lobbying, advocacy and community organising. This leads us to find that the primary variance among communities is in the type of activities undertaken rather than the level of group activity. In more privileged areas of Sydney, local groups are more likely to be constituted as traditional interest groups, including those that focus on post-materialist concerns. However, group activity remains substantial in less affluent areas, but manifests in different forms, including hybrid groups that combine service provision and advocacy.
