This study explores the climate change issue in the Tasmanian wine cluster. Following cluster theory, we predict knowledge exchange on climate change is widespread in the overall cluster, while component knowledge on climate change is exchanged more readily than architectural knowledge. We also predict knowledge exchange on climate change is more widespread within sub-clusters than between them. Using network analysis and a quantitative approach, all three hypotheses are rejected. A discussion of the findings and their implications is presented along with future research directions.
