This study investigates the extent to which a group of Australian preservice and early career secondary school music teachers of East Asian heritage are likely to teach aspects of their heritage music. It is positioned against a background of national multiculturalism and approaches to cultural inclusivity in Australian society, as well as the long-standing notion of ‘Asia literacy’ in Australian education and the national cross-curriculum priority (C-CP) of ‘Asia and Australia’s engagement with Asia’. The study’s findings indicate that the participants identified with their ancestral cultures to varying extents, generally had very limited knowledge of and experience with their heritage music and in general were reluctant to teach their heritage music. The authors suggest that the slow rate of progress towards culturally diversifying Australian music classrooms is related to complex matters and attitudes surrounding race in the country. The study proposes developing Cayari’s concept of ‘Asian spaces’ as a means of increasing the presence of East Asian music in Australian schools and of supporting teachers of East Asian heritage in the workplace. Finally, the authors emphasise that culturally diversifying the content of music classrooms can be undertaken by teachers of any cultural background.
