The Alliance was established in 2014 as the Wollondilly Health Alliance in response to growing and complex health challenges facing the Wollondilly community. Rapid population growth, changing demographics and increasing demand on health and social services highlighted the need for a more coordinated, place based approach. South Western Sydney Local Health District, South Western Sydney Primary Health Network and Wollondilly Shire Council signed a formal Memorandum of Understanding (MoU) to strengthen collaboration, improve health outcomes and address the broader social determinants of health through shared planning and action.

In 2025, partners reaffirmed and strengthened this commitment by signing a five year Memorandum of Understanding (MoU) through to June 2030. The new MoU brought together the Wollondilly Health Alliance and the Health in Planning Partnership, consolidating earlier collaborative efforts into a single, unified alliance. The updated agreement reflects a matured partnership and a stronger focus on integrating health, planning and community development. It recognises the importance of embedding health considerations into growth, infrastructure and service planning to support the long term wellbeing of a rapidly developing Wollondilly community.

Wollondilly is experiencing significant population growth and infrastructure development, bringing new opportunities as well as emerging health and social challenges.

The Wollondilly Health & Planning Alliance works collaboratively to ensure health considerations are integrated into planning and community development. By aligning efforts across government and the health sector, the Alliance aims to:

• Improve health and wellbeing outcomes for Wollondilly residents
• Strengthen connections between health services and the community
• Support prevention, early intervention and access to care
• Plan for the health needs of a growing population

As the community continues to grow and change, the Alliance will adapt its priorities and projects to respond to emerging needs and support a healthy Wollondilly community.

The Wollondilly Health & Planning Alliance is a partnership between organisations across local and state government. These include:

• South Western Sydney Primary Health Network (SWSPHN): Supports primary health care services and helps improve coordination and quality of care across the region
  
  
• South Western Sydney Local Health District (SWSLHD): Provides public hospital, community health and preventative health services
  
  
• Wollondilly Shire Council: Supports the community through local services, facilities, planning, advocacy and community development programs

The partners work together to share knowledge, align priorities and deliver better outcomes for the community.
