Since 2019, Western NSW Local Health District has been trialling a shared general practitioner (GP) service across Tottenham, Trundle, Tullamore, and Trangie (the 4Ts) following the closure of every private GP practice in town. Western NSW Local Health District shares doctors, nurses, and administrative staff across the four towns, coordinated by a medical centre manager. The clinics are co-located within the town's Multipurpose Service (MPS).

This single-employer model was evaluated through the Collaborative Care Program. The aim was to understand how well the shared GP service has addressed community needs and to refine the model to make it sustainable.
