Dimond Gorge, Canyon in Kimberley region, Western Australia.

Dimond Gorge is a canyon carved by the Fitzroy River, whose red and rust-colored sandstone walls rise steeply on both sides. The gorge stretches through ancient rock layers, creating narrow passages and deep pools where the river flows.

In the 1960s Dimond Gorge was considered as a site for peaceful nuclear explosions. Later proposals sought to dam the Fitzroy River here to supply agriculture in the Kimberley and the city of Perth. In 2023 the Bunuba National Park was established, stretching from Dimond Gorge to Geikie Gorge and including Danggu Gorge National Park.

The gorge lies within Mornington Sanctuary, and in 2023 the Bunuba National Park was established, stretching from Dimond Gorge to Geikie Gorge and including Danggu Gorge National Park. The Bunuba name Danggu is used for the national park at Geikie Gorge, showing that Bunuba country and its names now frame this stretch of the Fitzroy River.

Access to the gorge requires a 24-kilometer journey from Mornington Wilderness Camp, where canoes and gear are available for rent. The cooler months offer the most comfortable conditions for exploring, as temperatures are moderate and water flows reliably.

Short-eared rock-wallabies make their homes in the rocky outcrops and cliff faces throughout the gorge. These small marsupials are difficult to spot but their presence reveals how the gorge provides shelter for wildlife adapted to harsh terrain.
