Public health partner authorities-How a health in all policies approach could support the development of a wellbeing economy.

Issue Addressed: Collaboration and partnerships across sectors are critical to the realisation of a wellbeing economy. Wellbeing SA-a government agency in South Australia-utilises a partnership mechanism under the state's public health legislation to achieve collaborative action for improved population health and wellbeing: Public Health Partner Authorities (PHPAs).

Methods: The establishment and implementation of PHPAs draws strongly on the principles and practices of South Australia's Health in All Policies (HiAP) approach. This includes the utilisation of cross-sectoral partnerships to facilitate the implementation of co-design and co-benefits principles to deliver policies that support improved population health and wellbeing, while simultaneously delivering other societal benefits. Partnerships also facilitate the sharing of knowledge and resources, and the creation of joint solutions to complex policy issues.

Results: PHPAs have been reported to offer a valuable, evidence-based and practical mechanism for embedding key concepts of wellbeing into the policies, practices and programs of other sectors, and provide the potential as one important tool for the formation of a wellbeing economy.

Conclusions: The achievement of a wellbeing economy is dependent on collaboration within and between sectors, and through strong community engagement. Developing a joint and inclusive understanding of wellbeing and its importance as a societal goal is critical, and can only be achieved through collaborative approaches. The implementation of PHPAs in South Australia has demonstrated the importance of partnerships to address complex issues across sectors, and has identified key elements to successful partnerships. SO WHAT?: South Australia's experience in implementing PHPAs and HiAP has demonstrated how health promotion practice, policy and research that incorporate successful partnerships can support high quality, effective intersectoral collaboration for the benefit of citizens, including some lessons that may be worth considering in the development and realisation of a wellbeing economy.
