Australia’s ageing population is increasing demand for accessible, continuous and coordinated primary care. General practice nurses (GPNs) are well positioned to support older Australians through chronic disease management, prevention, self-care education and multidisciplinary care, yet their contribution depends on workforce stability and meaningful use of scope of practice. This presentation synthesises findings from linked analyses of the 2023 Australian Primary Health Care Nurses Association Workforce Survey, including more than 1400 GPNs. The project examined generational differences in satisfaction, intention to stay and further education, alongside associations between working to full scope and intrinsic and extrinsic job satisfaction. GPNs across generations were generally satisfied with their roles; however, younger cohorts were more highly educated, more likely to seek further education and more likely than older nurses to intend to remain in general practice over the medium term. Scope-of-practice findings further showed that fuller role utilisation was consistently associated with more favourable satisfaction across workplace and professional domains. In adjusted analyses, autonomy in choosing work methods, variety in work, physical working conditions and opportunities to use abilities remained significantly associated with scope-of-practice frequency. These findings suggest that retention and service capacity cannot be strengthened through recruitment alone. Policies and practice models must enable GPNs to use their capabilities, access continuing education, and contribute fully to interdisciplinary care. In the context of delayed GP access, especially in regional, remote and disadvantaged communities, optimising the GPN role offers a strategy for supporting ageing well, chronic care innovation and sustainable primary care for older Australians.
