In this article, the authors reflect on their design and delivery of a new undergraduate unit offered by the School of Education, University of Western Sydney. The paper offers a critical review of multiculturalism in teacher education and examines theories associated with cosmopolitanism in the education context. The authors examine the ways in which a ‘cosmopolitan imagination’ might have relevance in contemporary contexts of diversity in Australia, and particularly in the western and south-western Sydney region in which they teach.
