The first call is not always to the council. First establish whether the tree stands on the neighbour’s private land, your land, or public land such as a street or park. Then separate the tree risk from the cost of the fence.
Route the problem by location
- Public tree: report it to the local council in NSW or ACT Government/Fix My Street. ACT nature-strip street trees are government-maintained and residents must not prune them.
- Neighbour’s private tree: write to the tree owner with photographs and propose an arborist inspection or temporary safety work.
- Unclear boundary: check a survey, title, council map or ACTmapi. Do not infer ownership from the canopy or root direction.
Build four evidence files
- Danger: images of lean, broken limbs, collapse or contact with wires. Call 000 for a threat to life and SES for storm assistance.
- Causation: a qualified arborist’s explanation of which tree caused or threatens the damage and how.
- Loss: the fence’s previous condition, damage, repair quotes and temporary make-safe cost.
- Notice: when the owner or government was told and how they responded.
NSW: the Trees (Disputes Between Neighbours) Act provides a Land and Environment Court path for orders concerning pruning, removal, prevention of damage and compensation. Council permits and protected-tree rules still need checking before work.
ACT: ACT Government manages public trees. Private trees are maintained by their owners but may be protected by Urban Forest rules. Before major pruning or removal of a protected tree, check with Access Canberra.
The fence may separately involve dividing-fence contributions, insurance and negligence. Deal first with safety, a shared arborist and temporary repair, then allocate final cost.
This is general routing information. It cannot decide tree ownership, negligence or compensation.
