About the park

The creation of Glenthorne National Park will see coordinated park planning and management across several important parcels of land including the Glenthorne property, O’Halloran Hill Recreation Park, Marino Conservation Park, Hallett Cove Conservation Park, Happy Valley Reservoir and areas of the Field River Valley. The total area is more than 1,500 hectares, which is bigger than Belair National Park. This will ensure that these important sites are managed to conserve their unique values, and for the collective value they provide.

Cultural significance

The Kaurna People are the Traditional Owners of the lands and waters of the greater Adelaide region, including the new Glenthorne National Park. They maintain a deep relationship with Country, and have done so for tens of thousands of years through their customs and Tjukurpa.

Tjukurpa, which includes cultural stories and lore, is vital to understanding the cultural significance of Southern Adelaide, and will profoundly influence the way the new Glenthorne National Park is managed.

Heritage and European History

The new Glenthorne National Park will include a number of historically important areas that will be preserved as part of the park.

The Glenthorne property has a rich history, settled in 1839 by the state’s first police commissioner Major Thomas Shuldham O’Halloran. It has been used as a farm, a training ground for military horses in WWI, a research facility from 1949, and is now set to become a heritage precinct within Glenthorne National Park.

Each of these phases of history are reflected in the historical building remains on the site, dating back to the 1950s.

The old Worthing Mine buildings in the Lower Field River Valley also provide an example of how copper mining took place in South Australia in the 1800s.

Plants and animals

Creating Glenthorne National Park will not only benefit the community, but help preserve, re-establish and re-connect important habitat for native plants and animals.

There are some important areas of vegetation that will be included in the Glenthorne National Park, including:

  • The Glenthorne property, which is located within nationally important greybox grassy woodland, with some scattered remant greybox trees and areas of grassland remaining on the site.
  • The Lower Field River, which is the last undeveloped catchment in metropolitan Adelaide and, although the valley has largely been cleared for agriculture or grazing, provides a `significant biodiversity corridor linking the hills to the coast.
  • Marino Conservation Park, which conserves the last remaining stands of coastal heath vegetation along this part of the Adelaide coastline, forming a green buffer between the suburbs.

Managing this land under a single national park management plan will create and expand wildlife and vegetation corridors in the southern suburbs, supporting native plants and animals to survive and thrive.


Geological significance

Hallett Cove Conservation Park has some of Australia’s most important geological formations, which can be viewed from the stunning boardwalk through the park. The outstanding glacial pavements along the northern cliff tops are the best record of Permian glaciation in Australia, formed during an ice age 280 million years ago, and have international significance.
