Burke and Wills Dig Tree, Colonial expedition site at Cooper Creek, Queensland, Australia.

The Burke and Wills Dig Tree is a heritage-listed coolibah eucalyptus on the banks of Cooper Creek at Nappa Merrie Station, in the Shire of Bulloo, Queensland. Two adjacent trees were blazed on 21 April 1861: one bears the word "DIG" and the location of a buried store, the other the letter "B", the camp number "LXV" and the dates of arrival and departure. The photograph shows a single upright, roughly triangular grey stone monument with no visible inscription, standing on bare ground with trees and the riverbank behind it.

On 21 April 1861 William Brahe and his party blazed two coolibah trees at Camp LXV on Cooper's Creek before leaving for Menindee. One blaze carried the word 'DIG' and the location of stores buried nearby: 50 pounds each of flour, oatmeal and sugar and 30 pounds of rice. Burke's party reached the camp that same evening and found Brahe gone.

The carved inscriptions show how explorers left messages when they needed to communicate across vast distances. These markings reveal the resourcefulness of people trying to survive in unfamiliar land without modern tools.

The site is well marked and easy to walk around on your own, with parking near the entrance. Visit during cooler months when temperatures are more comfortable for exploring the area.

A nearby tree called the Face Tree holds a carved portrait of Burke that was added years later as a tribute. It shows how people who came after the explorers wanted to honor their memory.
