This article focuses on a comparative study of how diverse subject disciplines in different higher education institutions in Australia and Hong Kong approached the challenge of internationalising the curriculum (IoC). Case study analysis identifies five conditions conducive to improving intercultural student interaction, engagement and adaptation through an internationalised higher education curriculum. The findings suggest that opportunities for IoC, such as those outlined, afford multiple benefits for both domestic and international students in higher education. These include, better cross-cultural mixing, intercultural competency development and adaptation to different higher education contexts. Implications for higher education institutions interested in creating conditions that facilitate an internationalised curriculum are discussed.
