Tourism researchers have identified the impact of perceived risk on destination choice and travel behaviour, and differences in general traveller risk perceptions based on both traveller and trip characteristics. However, such research has neglected the travel of international university students, despite the expansion and economic importance of this market. This paper outlines an exploratory study conducted on international university students studying at an Australian university. A total of 407 valid responses from the sample were achieved. Factor analysis identified four main risk factors which were labelled 'human-induced risk', 'social-psychological risk', 'financial risk', and 'health risk'. Student origins were found to influence risk perceptions. In particular, Asian students perceived higher levels of human-induced and social-psychological risks compared with students primarily from America and Europe. Travel experience and repeat visitation significantly reduced risk factors apart from health risks. Financial risks were higher for students planning to travel in Australia compared with Asia and America. The implications for destination marketing are considered, and future research avenues based on the results are outlined.
