Tomaree National Park, Nature reserve in Port Stephens, Australia.

Tomaree National Park stretches along the Tasman Sea from Fishermans Bay to Shoal Bay, passing Boat Harbour, One Mile, Nelson Bay and Fingal Bay. It combines rocky coastal sections, sandy beaches and heathland behind them, and is the only place where the acidic volcanic rock rhyodacite can be found.

The military structures on Tomaree Head are World War II gun emplacements built in 1941, not a fort. They housed the No. 20 Radar Station RAAF, and the concrete remains can still be seen on the headland.

Tomaree National Park lies within the traditional land of the Worimi Aboriginal people, for whom it provided food, medicine and shelter. The park's entry signs mark the boundary of this country, and the same coastal resources that sustained the Worimi remain visible along the beaches and headlands.

The park has extensive trails that lead to beaches, viewpoints, and historical locations throughout the area. Visitors should wear sturdy footwear and prepare for changing weather conditions, especially on elevated paths.

The park contains rare volcanic rock formations of rhyodacite that exist nowhere else in the New South Wales region. These geological layers formed millions of years ago and give the landscape its distinctive character.
