This paper draws from an institutionally-funded phenomenological study of international PhD students' academic acculturation, which focuses on the distinctive strengths, challenges, and hidden opportunities facing this cohort within the context of their transition from one academic culture to another. The first section introduces the theoretical base employed in the study and is then followed by exploring the conceptualisations of the hidden curriculum and its associated concepts: "the third space" and "darkness in higher education". Drawing upon our study findings, the second section illustrates practical exemplars of finding and harnessing the hidden curriculum. Without discounting the wide range of formal and informal institutional support provisions designed to facilitate international PhD students' acculturation to a new academic setting, our study findings strongly endorse that students themselves have a crucial role to play in their complex transitional journey. Our study also offers a unique insight, i.e. if found, the hidden curriculum is an effective tool not only for international PhD students' coping and survival but even more importantly, in thriving in new societal and academic contexts.
