One of the most prominent and successful examples of the use of nonviolent direct action in Australia has been the environmental group North East Forest Alliance (NEFA) which ran a successful campaign to protect old growth forests. NEFA's campaign involved over a decade of blockades, and other forms of direct action including a significant occupation of the entire NSW Forestry department building in November 1992. NEFA also ran a number of court actions in conjunction with its direct action campaigns and was successful in most of these. The history of NEFA's campaigns is well documented including a case study provided in The History of the NEFA campaign has also been explored by the same author (Aidan Ricketts) in a book chapter "Om Gaia Dudes" which explores the cultural significance of the old growth forests campaign
