Statement of Significance

Before the introduction of spotter planes to look out for fires, a network of fire lookout trees spread out across the south-west forests. From the top of these trees, foresters used to scan the landscape around them for the first signs of fire.

Selecting the tree
Foresters selected the Gloucester Tree to use as a fire lookout in 1947. It was one of eight lookouts built in the south-west between 1937 and 1952. To determine its suitability as a lookout tree, forester Jack Watson climbed it using climbing boots and a belt. It took him a gruelling six hours to reach 58 metres high and return.

A visit from Royalty
The tree was named after the then Governor-General of Australia, His Royal Highness the Duke of Gloucester. He visited the tree and watched the pegging of the ladder and lopping of the branches to construct the lookout. Apparently the Duke showed and interest in the tools used by the axemen. He tried his hand at using the auger to bore holes for the climbing pegs and remarked that it did not seem too difficult a task. The axeman replied “Come off it-you’re not through the bloody sapwood yet!”

Enjoying retirement
Today, the Gloucester Tree has retired from its duties as a fire lookout tree but is available for the enjoyment of visitors. You can climb 58 metres to the lookout structure which affords spectacular views over the surrounding karri forest and farmland.
