Five layers, not one
People assume tree law means "the council rules". On the Central Coast there are five layers, and a tree can be lawfully removable under one and prohibited under another.
1. Council planning controls
Central Coast Council's tree and vegetation provisions, sitting within its planning framework, are the layer that applies to most suburban trees. They set the size thresholds above which approval is required, the exemptions, and the application process. One set covers the whole region following the 2016 amalgamation of Gosford and Wyong councils.
This is the layer covered in detail in the council approval guide.
2. State biodiversity and native vegetation law
The Biodiversity Conservation Act 2016 and associated instruments regulate clearing of native vegetation, threatened species habitat and ecological communities. This layer bites hardest on rural and semi-rural land — the Yarramalong and Dooralong valleys, Mangrove Mountain, Kulnura, Somersby — and on any block carrying biodiversity mapping.
The important point for landholders: being on acreage does not make clearing easier. It frequently makes it harder, because this layer applies in addition to Council's provisions and the agricultural exemptions are narrower than most people assume.
3. Marine vegetation
Mangroves and seagrasses are protected under NSW fisheries legislation. This is not a council matter and council cannot authorise work on them. It is directly relevant on the Brisbane Water and Kincumber Broadwater foreshores — Kincumber, Davistown, Saratoga, Empire Bay and the Woy Woy waterfront — where mangrove fringes commonly sit between a house and a water view.
Penalties are significant and enforcement is real.
4. Electricity safety
Work near electricity network assets is regulated under NSW electricity safety law and the network operator's requirements. On the Central Coast the distributor is Ausgrid. Approach distances to conductors apply to everyone, and work inside them requires accredited personnel and often a scheduled outage.
No council permit authorises unsafe work near a power line, and no contractor's confidence substitutes for accreditation. The power line guide covers it.
5. Neighbour and civil law
The Trees (Disputes Between Neighbours) Act 2006 provides a pathway to the NSW Land and Environment Court where a tree is causing or likely to cause damage or injury, and in defined circumstances where a hedge severely obstructs sunlight or a view.
Alongside it sits common law: the general right to abate an overhanging branch back to the boundary at your own cost, limited by any statutory protection on the tree and by liability for damage caused. The neighbour liability guide covers the practical side.
Also on public land
Street trees, verge trees and reserve plantings belong to Council. National park and state forest trees belong to the state. Neither is yours, regardless of proximity or litter, and clearing into them is prosecuted — see the fines guide.
Nothing here is legal advice
This is an orientation to the framework, not advice on your situation. For a specific tree, get the address checked against Council's mapping and, where the stakes are high, get a qualified arborist's written assessment and your own legal advice.
The regulations index lists the rest of the guides.
Frequently asked questions
Can I cut branches that overhang from my neighbour's tree?
At common law you may generally prune back to the boundary line, at your own cost, without entering their land, and the cuttings remain their property. That right is limited: it does not apply where the tree is protected under Council's provisions, and cutting so severely that you damage or kill the tree exposes you to a claim. In practice, talk to the neighbour and get advice before cutting anything substantial.
Is there a NSW law about trees between neighbours?
Yes. The Trees (Disputes Between Neighbours) Act 2006 allows a neighbour to apply to the NSW Land and Environment Court for orders where a tree is causing or is likely to cause damage to property or injury to a person, and in some circumstances where hedges severely obstruct sunlight or views. It is a formal process and it is the proper avenue when negotiation has failed.
Are mangroves treated differently from other trees?
Completely. Mangroves and seagrasses are protected marine vegetation under NSW fisheries legislation, which is separate from and additional to council tree controls. Cutting, trimming, poisoning or filling around mangroves without authorisation carries serious penalties and is actively enforced. This matters on the Brisbane Water and Broadwater foreshores at Kincumber, Davistown, Saratoga and Woy Woy.
