Prince Regent

Prince Regent National Park is a remote 635,000-hectare wilderness in the northern Kimberley protecting some of Australia's most pristine and spectacular landscapes, centred on the Prince Regent River and its exceptional gorge system. The park was one of Australia's first biosphere reserves (UNESCO, 1977) and remains one of the most ecologically intact areas of the continent. Towering 100-metre sandstone gorge walls, cascading waterfalls, and permanent river pools characterise the landscape. The park contains extraordinary concentrations of Wandjina and Gwion Gwion rock art, some of the world's oldest and most important cultural heritage. The marine-facing section includes the Montgomery Reef — one of the world's largest inshore reef systems.

Prince Regent's intact wilderness supports exceptional biodiversity. The northern quoll (Dasyurus hallucatus) maintains healthy populations here, protected by the distance from the advancing cane toad invasion. Rock wallabies inhabit the sandstone gorges. Freshwater crocodiles live in the river pools. The Gouldian finch — critically endangered — uses savanna woodland habitats. Saltwater crocodiles are present in tidal areas. The coastal section supports dugongs, sea turtles, and the extraordinary wildlife of Montgomery Reef, where manta rays, fish, and reef sharks are concentrated by the extreme tidal flows.

The park protects the full range of northern Kimberley vegetation communities — tropical monsoon forest in gorge environments, savanna woodland on plateau surfaces, mangrove systems in coastal inlets, and riparian gallery forest along permanent waterways. The botanical diversity reflects the Kimberley's status as a globally significant botanical region, with high levels of endemism and intact communities that have been largely undisturbed by European pastoral activities.

The Prince Regent River gorge is carved through the ancient Kimberley Craton — Proterozoic sandstones approximately 1.8 billion years old. The dramatic gorge walls, reaching 100 metres, display the horizontal bedding of these ancient sedimentary rocks. Montgomery Reef is a tidal reef phenomenon — as the extreme Kimberley tide ebbs, the reef emerges from the sea like a rising island, with waterfalls cascading from its edges and marine wildlife concentrated in the draining pools.

Extreme tropical monsoon climate. Wet season (November–April) brings intense flooding making the park inaccessible. Dry season (May–October) allows access by charter aircraft or expedition vessel. Montgomery Reef is accessible from the sea during the dry season when navigation is possible.

The Wunambal Gaambera people are the traditional custodians of the Prince Regent National Park country. The park contains hundreds of Wandjina and Gwion Gwion rock art sites of profound cultural significance. The Wandjina — ancestral creator beings represented in distinctive white-and-black paintings — are among the most recognisable images in Indigenous Australian art.

Prince Regent National Park was declared in 1964 and became a UNESCO Biosphere Reserve in 1977. Joint management with Wunambal Gaambera traditional owners formalises the partnership that has shaped park management. The park's ecological significance has attracted significant scientific attention.

Cane toad invasion, invasive weeds, and maintaining the ecological integrity of this globally significant wilderness are primary concerns. The Wunambal Gaambera Healthy Country Plan guides management.
