Objective: The needs and experiences of Chinese international students in the context of secondary education have been largely under-researched. Tertiary education research has shown international student populations are particularly susceptible to acculturative stressors, loneliness, and isolation in host cultures therefore it is important to consider these factors amongst secondary students studying abroad who are potentially even more vulnerable. Method: This qualitative research explored the experiences and challenges faced by Chinese secondary students in Australia and their help-seeking behaviour. Interview data was collected from 17 participants across two different school settings. Results: Thematic analysis identified three key themes; Adjustment Difficulties, Academic Difference and Help-seeking and support. It was found that the challenges experienced by international students consisted of living, academic and sociocultural factors. Participants reported experiencing cultural discrimination but were reluctant to seek formal help for this. Conclusion: The results have implications for Australian secondary schools given the high number of international students that study in the country. Recommendations are made for how international students can be better supported.
