The study of how ethnonationalists mobilize digital media is not matched in size by an investigation into the progressive activists digitally mobilizing against them. This is especially true in diaspora communities, which form the focus of this work. In this paper, we discuss diasporic online progressive activism against one form of ethnonationalism, Hindutva. Situating our argument in the context of the Indian Australian diaspora, we argue that the study of activist media ecologies which seek to resist Hindutva is as critical as the study of Hindutva itself, but that scholarship on this kind resistance in diaspora remains sparse. We suggest that the Australian case–witnessing a critical acceleration in Hindutva mobilization since 2020–provides a unique opportunity to understand the role of digital media at the nascence of online resistance. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
