The National Trusts of Australia have collaborated to create a National Register of Significant Trees. This Register is consistent with our mission to protect and celebrate Australia’s heritage.

Significant Tree Committees in each state and territory comprise experts in a range of relevant fields including arboriculture, botany, heritage conservation, environmental management. The Committees meet at least three times per year to discuss issues regarding significant trees.


The role of the Significant Tree Committees will be to seek and assess nominations for significant trees against the nationally agreed criteria, and compare the tree to other registered trees of the same species and criteria on the Register. The Significant Tree Committees will resolve the tree’s level of significance, or may reject the nomination if the tree is considered of local or no significance. The Significant Tree Committees will be responsible for maintaining and updating the Register. The Significant Tree Committees will also promote awareness of the cultural value of significant trees, and advocate for statutory protection for registered trees under the relevant local Planning Scheme.
