This article is concerned with the internationalisation of higher education and student mobility for society and community engagement purposes. Drawing on the specific case study of Universiti Brunei Darussalam’s Community Outreach Programme overseas, it examines the programme’s operation in Vietnam as well as investigates Bruneian students’ experiences during their programme activities in this Asian country. The article also explores the impacts of such experiences on the students’ growth and transformations. The reported growth and transformations, on the one hand, demonstrate the importance of social engagement beyond campus and correspond to the internationalisation in higher education for society agenda recently advocated by international education scholars and practitioners. They also offer rich insights into (inter-Asian) student mobility for non-academic purposes, which remain largely under-researched. On the other hand, underlying the students’ transformative experiences are many issues associated with student safety and wellbeing that require ethical responses and appropriate adaptive pedagogies.
