Implementation of the Allied Health Assistant Workforce in the Australian Context: An Integrative Review

The Allied Health Assistant (AHA) workforce plays a critical role in enhancing the capacity, efficiency, and accessibility of allied health services across Australia. Considering significant structural reforms in sectors in which AHAs are employed, including the introduction of the National Disability Insurance Scheme (NDIS) and changes to aged care funding, this integrative review synthesizes current evidence on the utilization of AHAs across diverse settings, disciplines, and sectors. A comprehensive search of peer-reviewed and government literature from 2007 to 2025 identified 38 studies and 18 policy documents. A concept analysis identified four key concepts: service efficiency and quality, capacity building through training, contextual and structural determinants of role implementation, and tensions between role innovation and professional boundaries. Findings highlight the positive impact of AHAs on therapy access and service delivery, the importance of context-specific training and supervision, and the need for supportive organizational structures. Despite growing recognition of the AHA role, gaps remain in outcome-focused research, particularly in mental health, disability, and aged care settings. This review underscores the need for targeted workforce strategies and policy development to optimize the integration and sustainability of the AHA workforce in Australia's evolving health landscape.
