Lake Gairdner National Park, Nature reserve with salt lakes in South Australia.

Lake Gairdner National Park protects three salt lakes, Lake Gairdner, Lake Harris and Lake Everard, lying just south of the Trans-Australian Railway and Stuart Highway. The photograph shows a broad, flat crust of pale pinkish-white salt reaching toward low hills, with small dark clumps of rock or soil scattered in front and a bare grey tree on a gravel rise at the left. The surrounding country is arid, with no free surface or underground water.

The sources do not record a founding date for the park. Its documented past centres on the Kokatha people, whose sacred sites in the area are still visited for ceremonies, and on the Glenloth Gold Battery Site at the western end on the shore of Lake Harris, listed on the South Australian Heritage Register as a place of archaeological significance. The park is ringed by pastoral leases.

The Kokatha people maintain strong connections to this land, which includes sacred ceremonial sites reflecting their traditional customs.

Public access is very limited because the park is surrounded by pastoral leases. The easiest entry is from the Yardea–Kingoonya road at The Brothers Well, a concrete catchment at the southern end of Moonaree Station. The dirt road is fine for two-wheel-drive vehicles when dry but may be closed by the Highways Department after rain.

The Glenloth Gold Battery Site lies at the western end of the park, on the shore of Lake Harris. It is listed on the South Australian Heritage Register as a designated place of archaeological significance, recording gold-processing work in this remote country.
