This study assesses the impacts of projected climate change on Australia's tourism industry. Based on application of the Tourism Climatic Index, it investigates potential changes in climatic attractiveness for Australia's major destinations, and discusses implications for tourist flows and tourism planning, development and management. Australia may see considerable changes in spatial and temporal patterns of climatic suitability for tourism, with a southward shift in the most desirable conditions and a decline in the climatic attractiveness of northern locations. For destinations in which conditions are projected to decline, increased investment in indoor amenities may become increasingly necessary; where conditions are projected to improve, the provision of adequate infrastructure to accommodate potential increases in visitation and implementation of mechanisms to minimise the impacts of excess use may be more important. Adoption of a pro-active rather than reactive stance to climate change will maximise the ability of tourism stakeholders to successfully adapt.
