With the tourism industry expanding post-2001, research on the impacts of tourism development continues to be important. Previous research has focused both on the types of impacts on the residents and the segmentation of the host community. Most of these studies have used attitudes as the clustering base. Although the resultant cluster groups have been able to discriminate community groups who either support or oppose future tourism development, these groups are difficult to identify in the community and the influence these attitudes have on the behaviour of residents remains unknown. This research investigated the link between positive and negative attitudes and the residents' intentions to act either to support or protest future tourism development. The results found no significant relationship between negative intentions to act (protest) and demographics, attitudes or the various community cluster groups. However, positive intentions to act (support future development) were related to gender, age, education, life cycle, length of residence and tourism business connection. Further, positive intentions to become more involved in tourism development within the community were related to both positive and negative attitudes. Finally, this research found that residents who traditionally involved themselves in proactive community groups had the strongest intention to ensure future tourism development benefited the community. Implications for the tourism industry, local government and the management of future tourism development were explored.
