Toolbrunup is among the highest peaks in the Stirling Ranges in Western Australia.

Toolbrunup is made from sediments deposited during the Ediacaran Period and later metamorphosed to quartzites and shales.

The first European to climb the peak was Robert Dale,[2] who did so in 1832 when he passed through the area.

John Septimus Roe did the same three years later and the botanist James Drummond followed in the 1840s and returned several times to collect and identify plants in the area.

[3] The traditional owners of the area are the Minang[4] and Koreng peoples.
