In culturally and linguistically diverse school settings, English as an Additional Language or Dialect (EAL/D) specialist teachers play a critical role in fostering equitable, socially just, and responsive learning environments. In Australia, EAL/D learners are students whose first language is not Standard Australian English (SAE) and who require targeted support to develop proficiency in SAE. This paper reports on a study examining EAL/D teachers’ reported pedagogical practices that nurture multilingual students’ plurilingual repertoires as acts of social justice. Framed through pedagogical judgement—encompassing action, reasoning, and responsibility—the study explored how teachers leveraged students’ cultural and linguistic resources as learning assets. Data were generated through in-depth semi-structured interviews with five EAL/D specialist teachers working with newly arrived Ezidi refugee-background students in a regional town in New South Wales. Findings indicate that teachers enacted inclusive, plurilingual practices grounded in strong pedagogical reasoning and a moral commitment to equity. Despite recognising persistent monolingual and deficit discourses, teachers actively challenged these narratives by affirming students’ linguistic and cultural identities.
