This paper compares and contrasts the management systems and governance structures of two island sites with national and international World Heritage recognition: Lord Howe Island (off the mid-east coast of Australia) and Fernando de Noronha (off the north-east coast of Brazil). Using historical and contemporary references, the paper explores the manner in which two distinct approaches to governance are implicated in the daily living of community members, and considers their socioeconomic activities. We use the case of tourism and World Heritage management as examples of the complexities involved in the different forms of governance structures adopted by these two small oceanic islands: similar in nature and official status, but significantly different when the outcomes of their governance practices are analysed. In the final part of the paper, we suggest mechanisms and approaches that can promote sustainable local engagement with island issues. © 2013 - Institute of Island Studies, University of Prince Edward Island, Canada.
