Positioned just south of Wyndham, Western Australia, close to the rustic allure of The Diggers Rest and the essential Moochalabra Dam, the Boab Prison Tree marks a significant point of historical interest.

A hollow behemoth, this Adansonia gregorii (Boab) tree on the King River road was more than just a part of the landscape; it was a silent witness to a turbulent chapter of Australian history.

In the late 19th century, as Wyndham grew as a frontier town, its police noticed something intriguing about the large Boab.

The tree, already marked by nature with holes in its upper branches, revealed its hollow nature.

It was 1890s practicality that transformed this giant into the Hillgrove Lockup, a makeshift prison for Aboriginal prisoners en route to Wyndham for trial.

Historical accounts tell a vivid tale of its use—a bottle tree with a storied past.

When “blacks were bad,” as an old 1931 news clipping uncomfortably phrases, the tree’s spacious hollow (over 100 square feet of dark, earthen room) served as a nighttime cell for up to 30 prisoners, though this number might be an overestimation.

The 1940s brought more tales of makeshift incarcerations under the shadow of the Boab.

One evening, a trooper found himself with too many prisoners and too little space within the tree. The solution was harsh yet pragmatic; he chained some prisoners to the tree’s massive trunk.

One of these prisoners, described in the records as a man of imposing build, managed to escape by the morning light, leaving behind only the bent remnants of his iron chains, shaped now like a hairpin.

As decades passed, the tree grew in girth and lore, measuring nearly 40 feet in circumference.

Inscribed on its trunk was “Hillgrove Police Station,” a title that seemed to anchor the tree in its role in local law enforcement.

This inscription, along with the names and initials of countless travelers, was deeply carved into the tree’s soft bark.

These marks have faded over time, much like the memories of those who passed through its shadow.

By 1966, clarity was needed as confusion arose with another Boab Prison tree in Derby, which, contrary to some reports, had never been used as a prison.

This distinction underscored the unique, if somber, role of the Wyndham tree in Australia’s penal history.

Today, the Boab Prison tree near Wyndham is not just as a natural wonder, but a poignant reminder of its past life as a prison.

It continues to draw visitors, serving as a historical marker that prompts reflection on the intersection of natural beauty and human history—a tree that locked away more than just secrets in its hollow heart.
