The historical significance of the Derby Prison Tree is rooted in its reported use as a makeshift lockup for Indigenous prisoners in the late 19th to early 20th centuries, as they were being transported to Derby for trial or imprisonment.

Despite its notoriety and the stories that have circulated about its use as a holding cell, there is no concrete evidence to confirm that it was ever actually used to house prisoners.

These accounts are part of the oral history and the lore surrounding the colonization period in Australia, reflecting the treatment of Indigenous peoples during that era.

The tree itself, a majestic Boab, stands as a symbol of the complex and often painful history between European settlers and Indigenous Australians.

Today, it is recognized more for its cultural significance and the stories it represents rather than its historical function.

As such, the Derby Prison Tree is a significant landmark, offering insights into Australia’s colonial past.


Situated approximately 6 kilometers south of Derby, Western Australia, near the King Sound, is the remarkable Boab Prison Tree, also known as Kunumudj.

Derby is part of the Kimberley region, a place celebrated for its extensive wilderness, dramatic landscapes, and important cultural heritage sites.

Accessible via road, this natural landmark draws visitors keen to explore its unique characteristics and delve into its historical and cultural significance.

Type of Tree

The Boab Prison Tree in Derby has a girth measuring around 46 ft (over 14 metres) and is a specimen of the Boab tree, scientifically known as Adansonia gregorii.

Boab trees are part of the Adansonia genus, which also includes several other species such as the famous baobab trees found in Madagascar, mainland Africa, and the Arabian Peninsula.

Adansonia gregorii is unique to Australia, predominantly found in the Kimberley region of Western Australia and parts of the Northern Territory.

Boab trees are known for their distinctive, bottle-shaped trunks, which can store large quantities of water, and their broad, spreading canopies.

These trees can live for hundreds, sometimes even over a thousand years, reaching impressive sizes.

The trunk’s girth is massive, allowing it to survive in arid conditions, and the tree produces large, white, night-blooming flowers and a fruit that is rich in vitamin C.
