Parliamentary Secretary for the Hunter Catherine Cusack said the now project, part of the NSW Government's $100 million pledge to build 20 HealthOne centres across the state, would be known as Tomaree Community Hospital and Health Centre.

"Construction of the Tomaree HealthOne facility commenced in late 2018 and aims to create a stronger and more efficient primary health care system that allows General Practitioners to work with community health providers and other health professionals in multidisciplinary teams," she said.

"This project delivers services tailored to residents of the Tomaree Peninsula including general practice, expanded medical imaging, community allied health, pathology and dental.

"The new hospital now has one entrance and one reception for all health services delivered on site, making it easier for people to navigate, and will service the community with the added benefit of being directly connected with the hospital, providing patients with an integrated health care experience.

"I would like to thank the local community for their patience during construction and especially thank the nurses, doctors and other hospital staff for their invaluable input into the project."

The Tomaree HealthOne project, touted as a "one-stop-shop" for health services for Nelson Bay, was announced in November 2017.

Graph Building was named as the contractor and an official sod turning ceremony was held at the site of the project, on the grounds of Tomaree Community Hospital, a year later, in November 2018.

The project was delivered in four stages starting with the build of a new, southern carpark in late 2018.

This progressed to the construction of the 1300 square metre health centre which was completed in late 2019, quickly followed by the kick-off of services in the new patient consult rooms.

Stage three of the build, carried out early in 2020, included the demolition of the old demountable community health and medical centre buildings.

The final stage of the project was the connection of the new HealthOne extension with the existing community hospital.

This work included the refurbishment and integration of the existing Emergency Department waiting area, reception, triage and consult rooms.

Finally, access to the hospital and health clinic was moved from Trevally Street to Kerrigan Street at the end of March.

"A significant focus for the HealthOne program includes improved information and technology systems, which will vastly improve connectivity and collaboration between health service providers in the region," Ms Cusack said.

"Having followed this important project closely through design and construction, I particularly appreciated the feedback from nurses and other staff on-site. I have been extremely impressed by Hunter New England Health's vision and leadership.

"Their appointment of a 'change management' project leader who ensured everyone's ideas and needs could be maximised and inconvenience minimised. This has been a fantastic case study in capital works excellence and I offer heartfelt thanks to all who contributed."
