The Big Tree is a large, well-preserved River Red Gum (Eucalyptus camaldulensis), located at the corner of Fryers Street and Ballarat Street. It is thought to be one of the largest in Victoria, with a height of 34 metres and circumference of 9.35 metres at the base. The tree is estimated to be between 500 and 1000 years old.

The Big Tree is listed as a tree of State significance on the National Trust’s Register of Significant Trees of Victoria for its “outstanding size, curious fusion of branches, as an outstanding example of the species and as an important landmark.”

The National Trust regards its conservation as vital to the local community and the state as a whole. Already an ancient giant when the first white settlers arrived in the 1840s, the Big Tree has played an important part in the cultural and social life of the Guildford community. This wonderful tree survives as an important symbol and a link between our community and its traditional owners, the Dja Dja Wurrung people.
