The term has outlived the instrument
Councils in New South Wales used to issue stand-alone Tree Preservation Orders. That mechanism has largely been absorbed into the planning system: protection now sits in a council's development control plan and local environmental plan rather than in a separate order.
The phrase persists in conversation, and for practical purposes it still means the same thing — the tree cannot be removed or substantially pruned without approval. On the Central Coast the relevant provisions are Central Coast Council's, applying uniformly across the whole local government area.
What gets protected
Size thresholds. The main mechanism. Trees above a specified height and trunk diameter require approval. The thresholds capture far more ordinary suburban trees than most owners expect, including a lot of planted exotics.
Mapped land. Biodiversity, riparian, coastal and heritage mapping all add protection. On the Central Coast this covers a great deal of land — the escarpment behind Gosford, the lake and creek margins, the bushland fringes at Avoca Beach and Kincumber, and the rural west.
Consent-tied vegetation. Trees shown on an approved landscape plan for a development are protected by the consent itself, separately from the general provisions. This catches a lot of newer estates and commercial sites.
Public trees. Street, verge, park and reserve trees are Council's outright.
What Council will and will not approve
Generally refused: removal of a healthy, structurally sound native tree because of leaf drop, bark litter, shade, blocked gutters, fruit, birds, or a preference for a view.
Generally approved: removal of dead trees, trees with demonstrable structural defects, trees causing damage that cannot be managed another way, and declared weed species.
Frequently approved as an alternative: crown reduction, thinning, deadwooding and clearance pruning where removal is refused. This is the outcome people most often overlook, and it usually solves the actual problem. Ask for it explicitly rather than treating a refusal as the end of the conversation.
Sometimes approved with conditions: removal subject to replacement planting, or subject to the work being done by a qualified arborist to a specified standard.
Making a case that works
Evidence beats argument. An application supported by a written assessment from a qualified arborist — ideally AQF Level 5 for anything Council will read closely — identifying a specific defect, with photographs, is treated very differently from a form saying the tree is too big.
Name the defect. Included bark at a co-dominant union. Basal decay with fruiting bodies. Root plate movement. A cavity in the main stem. Those are assessable facts. "It worries me" is not.
The signs a tree needs removing article describes what those defects look like.
If you get it wrong
Removing a protected tree without approval is an offence, the property owner is the primary target of enforcement, and remediation orders frequently cost more than the fine — see the fines guide.
The approval guide covers the process, and the legal overview covers the state law above it.
Frequently asked questions
Do tree preservation orders still exist in New South Wales?
Not as the stand-alone instruments they once were. Tree protection in NSW now sits within councils' planning frameworks — typically a vegetation management provision in the development control plan, supported by the local environmental plan — rather than in a separate tree preservation order. People still use the term TPO in conversation, and Central Coast Council's provisions do the same job.
What makes a tree protected?
Usually its size. Council provisions set height and trunk diameter thresholds above which approval is required, and those thresholds capture a lot of ordinary suburban trees. Beyond size, additional protection attaches to vegetation on land with biodiversity, riparian, coastal or heritage mapping, to trees tied to an approved landscape plan, and to all trees on public land.
Can I get approval to remove a protected tree that drops leaves on my roof?
Almost certainly not for that reason alone. Leaf, bark and fruit drop, shade, blocked gutters and general nuisance are not accepted grounds for removing healthy protected vegetation. What is accepted is demonstrable structural defect, disease, death, imminent risk, or damage to a structure that cannot be managed another way. Pruning is the usual approved remedy for nuisance.
What happens if the tree is protected but genuinely dangerous?
There is an exemption for trees presenting an imminent risk, and genuine emergencies can be made safe immediately. For anything short of imminent, lodge an application with a written arborist assessment identifying the defect. That assessment is what turns an opinion into evidence, and Council decisions on hazardous trees generally follow the evidence.
