The predicted growth of the aged care sector in Australia, driven by the ageing population, is expected to create an increasing need for workplaces to support the development for all kinds and classifications of workers to undertake their work within multicultural settings. This paper describes and elaborates the necessary and increasing requirement for workplaces to support adult learning in multicultural circumstances. A mixed methods approach was used to collect data from workers undertaking the role of carer in residential aged care facilities across the east coast of Australia. Arising from the collection and analysis of these data are contributions to knowledge including a conceptual model for understanding learning in multicultural settings. This research emphasizes a notion that cultural diversity has a fundamental influence on workplace learning in aged care and identifies practices to support cross-cultural communication, coworking and learning. Further, inter-worker learning is reinforced as a key enabler of performance in aged care work. Such contributions help to understand what influences workplace learning in multicultural settings and how it may be better supported.
