In Victoria, the responsibility for overhanging tree branches typically lies with the property owner on whose land the tree is located. It is the responsibility of the property owner to ensure that their trees and vegetation do not cause any obstruction or pose a risk to neighboring properties or public spaces.

If the branches of a tree extend beyond the property boundary and encroach onto a neighboring property, it is generally the responsibility of the affected property owner to address the issue. They may choose to discuss the matter with the tree owner and request them to trim or remove the overhanging branches.
However, it’s important to note that specific regulations and local council bylaws can vary, and they may have guidelines or requirements regarding tree maintenance and responsibility for overhanging branches. It is advisable to consult with the local council or relevant authorities in your area to understand the specific rules and responsibilities concerning overhanging tree branches in your locality.
