How hedge trimming works in Sydney
Legal Aid NSW says a hedge under the Trees (Disputes Between Neighbours) Act 2006 is two or more trees over 2.5 metres high, planted together to form a hedge. For these disputes, bamboo, tiger grass and giant clumping grass count as trees too.
For an order, the hedge has to severely obstruct sunlight to a window of a home on the neighbour's land, or a view from that home. The Court must be satisfied you've tried to sort it out first, and the neighbour and council must be served at least 21 days before the preliminary hearing.
The Court can order pruning or removal, but compensation for lost sun or views isn't available. Our neighbours' trees guide covers the wider rules.
Hedge trimming in Sydney: what's local
Big hedge plants can be trees to council
A tall screen can include plants big enough to fall under a DCP. Inner West prescribes trees 4 m or taller, and Willoughby trees over 4 m or with a crown wider than 3 m, so a hard cut on an old hedge may need approval.
Views aren't a council reason
Lane Cove says it doesn't allow large sections of trees to be cut for sun or views, and Willoughby generally won't approve removal for views or light. For a neighbour's hedge, the Trees Act is the route, not council.
Reaching over the fence
Lane Cove needs the neighbour's written consent if pruning means going onto their land or reaching across the boundary. Legal Aid NSW says cuttings from a neighbour's plant belong to them, so hand them back.
Council won't referee
Georges River says council can't make neighbours prune or mediate disputes, and points people to a Community Justice Centre, then the Land and Environment Court.

Hedge trimming in Sydney: what you can do yourself
You can

- Talk to the neighbour early, before a hedge turns into a dispute
- Keep dated photos if a window is losing its sun

Hiring an arborist for hedge trimming in Sydney
Agree a height everyone can live with, then hold it there with regular trims, which is kinder to the plants than a hard cut every few years. If you're the one losing sun, start with a friendly conversation and a photo record. Court is the last step, and Legal Aid NSW suggests getting a shade diagram from an expert before you apply.
