ABSTRACT Outbound student mobility has gained increased popularity over the past two decades. It involves an array of stakeholders including students, academics, mobility practitioners and home and host communities. Despite challenges, learning abroad creates a range of impacts on individuals, institutions, and society. Existing research on learning abroad largely concentrates on students’ motivations, activities and effects of outbound mobility on individual students. However, how learning abroad may potentially contribute to transnational connections is largely under-researched. This article responds to a critical gap in the literature by examining not only how learning abroad in Vietnam enriches individual Australian students personally, professionally and culturally but also how such developments could potentially have broader transnational impacts. The article draws on a study including interviews with 24 Australian students learning abroad in Vietnam through the New Colombo Plan. It elucidates the students’ intercultural, personal and professional growth, especially on the humanistic aspects of global citizenship, through their deeper understanding of Vietnam, their formation of a relational capability, and a sense of empathy with the Vietnamese people. The article also highlights the value of Australian students' intercultural experiences and engagement with Vietnam to the society. In particular, it unpacks how Australian students' learning abroad in Vietnam could potentially contribute to enriching Australia-Vietnam connections and collaboration to respond to critical socio-economic issues such as climate change, economic development and poverty.
