Higher education internationalisation (HEI) emphasises the benefits of international research partnerships, knowledge production through education hub development, and global marketisation/exportation of education. The connections between internationalisation and student life are less documented in East Asian universities, particularly regarding social exclusion issues. This study takes an intersectional approach to explore and analyse students' social exclusion experiences at one international Hong Kong university using an anonymous online survey (n = 100). Thematic analysis revealed social exclusion in multiple student life areas across three major axes: Area of origin, particularly Mainland Chinese students; Sexuality, specifically lesbian, gay and bisexual-identified students, and the intersectionality of nationality, language and ethnicity. The study findings are situated within the sociocultural and political context of Hong Kong HEI since the mid-1990s. Internationalisation presents opportunities for Hong Kong universities to make needed commitments to addressing social exclusion issues, as they continue to affect campus ecologies and the increasingly diverse student population.
