Idalia National Park, Nature reserve in Queensland, Australia

Idalia National Park protects 144,000 hectares of mulga-covered tableland in the Gowan Range, 113 km southwest of Blackall. The Bulloo River rises here, and the park contains sandstone gorges and rock formations. Ruins of the Idalia and Collabara homesteads stand within its boundaries.

The reserve was established in 1990 following an official ceremony, marking its protected status. The two homesteads visible today date from an earlier colonial period and show the region's settlement history.

The park contains Aboriginal heritage sites: scatters of stone artefacts, stone arrangements and camping places. The German source also notes a network of walking tracks crosses the park, and the ruins of two European settler homesteads, Idalia and Collabara, stand within its boundaries. The park was opened in 1990 by Prince Philip.

Access requires four-wheel drive vehicles, particularly since heavy rainfall can make entry and exit impossible. Visitors should prepare for remote conditions and allow adequate time for their journey through the park.

The park protects rare yellow-footed rock-wallabies and endangered bridled nailtail wallabies, two marsupial populations that are difficult to spot elsewhere. These specialized species thrive in the mulga woodlands where they find shelter and food.
