In research which could reshape the multi-billion dollar tourism industry, select holidaymakers arriving in Tasmania are handed phones loaded with free data, than tracked via an app as they travel around the state. The result is detailed information on how long someone stands at a lookout, walks through a national park or browses an art gallery - potentially lucrative information for tourism operators. The project, undertaken by Sense-T - a research collaboration involving the University of Tasmania and the state government is the largest and longest of its kind in the world. So far 337 tourists have taken part in the project. Find out more.
