Topaz Road National Park, Nature reserve in Tablelands Regional, Australia.

Topaz Road National Park is a nature reserve covered with rainforest in the Tablelands region. Visitors walk through dense vegetation and experience the tropical forest environment that surrounds the upper Johnstone River valley.

The reserve was established in 1977 to protect this rainforest from development. The creation of this protected area reflected growing efforts to preserve Queensland's natural ecosystems.

Topaz Road National Park lies within the Wet Tropics of Queensland, a UNESCO World Heritage area listed in 1988. The park protects remnant rainforest in the upper Johnstone River catchment, and together with nearby nature refuges it adjoins Wooroonooran National Park. Its name comes from the small settlement of Topaz, reached by a side road east of the Atherton Malanda Road.

There are no visitor facilities in the park, so no trails, signs or water points exist; access is via a small road east from Topaz, about 10 km south of Malanda off the Atherton Malanda Road. Plan for a self-contained visit and take everything you need with you.

Despite covering only 0.4 km², the park has recorded 67 bird species, including the barred cuckoo-shrike, white-browed triller, black-faced cuckoo-shrike and yellow-breasted boatbill. It lies about 5 km south of Malanda, reached by a small road east into the Topaz settlement.
