Study Abroad (SA) is increasingly promoted by Australian universities and undertaken by students. SA places students in direct contact with other cultures, which can be an opportunity for language and culture learning, fostering intercultural friendships and understanding. Among Australian students studying in Japan, a popular option is a short-term program that includes a homestay: two or three weeks staying in the home of a local family.Although considerable literature is available investigating SA for one or two semesters, relatively few studies have examined short-term homestays. Similarly, the literature on Australians on SA programs in Japan is scarce, and does not focus on short-term homestays.However, the length of stay, the accommodation situation, and the particular combination of cultures involved are crucial components that determine students' experiences abroad and affect adjustment and learning. For these reasons, short-term homestay by Australian students in Japan warrants a dedicated study examining this particular SA context.The present study therefore investigates the specific ways in which being immersed in a new family situation for a short, concentrated period shapes the intercultural experiences of both Australian university students and the Japanese hosts of such students. It is a qualitative exploratory study examining the relational dynamics arising from this quite particular situation, and their effect on communication and expectations both during and after the homestay.The present project also differs from previous studies of SA in its focus on accounts of the homestay experience rather than on SA outcomes, and in the equal weight it gives to the perceptions of students and host families, rather than privileging student perceptions, in order to provide insights into the different beliefs, assumptions and expectations underlying misunderstandings and/or conflicts.Qualitative data were collected from three sources. Semi-structured in-depth interviews were conducted with nine Australian university students and nine host families (10 host parents) who participated in short-term Japanese homestays in 2009. These data were supplemented by diaries that the students kept about their intercultural experiences during their stay. In addition, the information provided to students and host families by the homestay organisers was examined. Content analysis of all data was undertaken to discover the ways in which ii both the students and host families assumed their roles and the expectations they held of each other and of homestay more generally. Three main themes emerged: expectations regarding the roles of family members during the stay, expectations of post-homestay relationships, and expectations of what intercultural learning should consist of. Some differences were evident in these expectations between host families and students, which also varied according to the gender, age and background of the interviewees.The analysis shows that both the students and their host families expected to...
