What Is a Tree Preservation Order?
The term ‘Tree Preservation Order’ (TPO) has a specific historical meaning in NSW that is worth understanding, because the way tree protection actually works today has evolved from that original framework.
Prior to 2006, NSW operated a statewide standard instrument TPO that provided a baseline of tree protection across the whole state. This was replaced when the Standard Instrument LEP (Local Environmental Plan) was introduced, shifting tree protection responsibility primarily to individual councils. Each council now manages tree protection through its own Local Environmental Plan and Development Control Plan (DCP), which means the rules differ meaningfully from one council area to the next.
The practical result is that ‘tree preservation order’ is now commonly used as a general term for any council-level tree protection provision, even though the specific instrument and threshold that applies depends entirely on which council your property sits in. When someone says their tree is covered by a ‘TPO,’ what they usually mean is that their council’s planning controls require approval before that tree can be removed or significantly pruned.
| 💡 The key question: The most important question is not ‘is there a TPO on my tree?’ but rather ‘does my local council require me to get approval to remove or prune this specific tree?’ The answer depends on your council’s current planning controls, the species of the tree, its size, its location on the property, and in some cases whether it is listed on a heritage register or biodiversity register. |
How Sydney Councils Protect Trees
While each council has its own provisions, most Sydney councils use similar mechanisms to protect trees. Understanding these helps homeowners know what to look for when checking their own council’s requirements.
Size thresholds
Most councils define protected trees by a minimum size, typically measured by trunk girth (circumference) at a standard height, or by trunk diameter at breast height (DBH). Trees above the threshold require development consent to remove. Trees below the threshold may be removed without approval, though some councils also protect specific species regardless of size.
Species-based protection
Some councils apply additional protection to specific tree species regardless of size. Significant native species, heritage-listed trees, and trees listed in local biodiversity registers may require approval even if they fall below the standard size threshold. Threatened ecological communities and associated habitat trees may also be separately protected under the NSW Biodiversity Conservation Act 2016.
Heritage and conservation overlays
Properties in heritage conservation areas or listed on the State Heritage Register may face additional tree protection obligations. Trees within these overlays are sometimes subject to heritage protection requirements separate from standard tree preservation controls. This is relevant for many properties in inner Sydney, North Shore, and Eastern Suburbs council areas.
Exempt work provisions
Most councils also define categories of tree work that are exempt from the approval requirement. Common exemptions include removal of trees with fewer than a certain trunk measurement, removal of clearly dead trees, removal of declared noxious weeds, emergency removals where the tree poses an immediate risk to life or property, and certain pruning activities that do not constitute more than a set percentage of the canopy. Exemptions vary significantly between councils.
| ⚠️ Never assume exempt: One of the most common and costly mistakes Sydney homeowners make is assuming that a removal falls under an exemption without actually confirming it with their council. What is exempt in one council area may require full development consent in the neighbouring council. Check with your council or an arborist before proceeding. |
Why Trees Are Protected: The Case for Preservation
The rationale for tree protection in urban areas like Sydney is well-supported by urban ecology and planning research. Trees are essential to the functioning of Sydney’s urban environment in ways that go beyond aesthetics. As the Sydney Tree Company’s preservation orders page notes, trees absorb carbon dioxide and airborne pollutants, release oxygen, improve the appearance of the urban environment, provide shade in summer, lower local temperatures, reduce erosion, and provide habitat for native animals. Sydney’s tree canopy is a genuine urban asset, and council tree protection schemes reflect this.
The Urban Heat Island effect is particularly relevant in Sydney: tree canopy in residential streets measurably reduces temperatures in adjacent areas during the hot months. Councils that have lost significant canopy cover to urban intensification have documented meaningful increases in local temperature. This is part of why approval requirements for tree removal exist: the loss of a mature tree is a community-level loss, not just a change to one property.
The Approval Process: What It Involves
If your tree does require council approval for removal or significant pruning, the typical process involves:
- Check your council’s DCP or LEP to determine whether your tree is covered and what threshold applies. Council websites publish these documents and most have a tree-specific guidance page. A link to every major Sydney council’s tree management information is available on our preservation orders page.
- Submit a development application (DA) or, where available, a complying development certificate (CDC) application, depending on the removal’s scale and the council’s processes.
- Arborist report is usually required. Most Sydney councils require a report from a qualified arborist (AQF Level 5 or higher) assessing the tree’s health, structural integrity, risk profile, and the reason for the proposed removal. This report accompanies the DA.
- Council assessment typically takes several weeks, though timelines vary. Some urgent removal applications are assessed more quickly where a credible risk assessment supports urgency.
- Conditions of consent are often attached to approval, including requirements to plant a replacement tree, sometimes of a specified species and size.
| 💡 Arborist reports: An arborist report prepared to Australian Standard AS 4970:2009 (Protection of Trees on Development Sites) is widely accepted by Sydney councils as the appropriate format for tree removal applications. Sydney Tree Company’s arborists can prepare compliant arborist reports as part of the removal process. |
Penalties for Non-Compliance
Removing a tree that requires council approval without obtaining that approval is a serious offence in NSW. Penalties differ between councils and circumstances but can include:
- On-the-spot fines under council environmental enforcement powers
- Orders to rectify the breach, which may include mandatory replanting requirements
- Court-imposed fines, which can reach tens of thousands of dollars for significant trees removed in protected areas
- Difficulties or complications in future development applications on the same property, where non-compliance history is recorded
These penalties are not theoretical. Sydney councils actively investigate reports of illegal tree removal, particularly for significant trees in areas where canopy preservation is a stated planning priority.

Frequently Asked Questions
How do I know if my tree needs council approval to remove?
The fastest way is to call your local council and ask specifically whether the tree you want to remove requires development consent under the council’s current DCP provisions. You will need to describe the tree’s location on the property, approximate trunk measurement, and species if known. Alternatively, Sydney Tree Company’s arborists assess trees across all Sydney council areas and can advise on the applicable requirements as part of a site consultation.
Can I remove a dead tree without council approval?
Many Sydney councils include dead tree removal as an exempt category, meaning approval may not be required if the tree is confirmed dead. However, the definition of ‘dead’ for the purpose of the exemption, and whether the exemption applies in your specific council and property type, must be verified. Some councils require a qualified arborist to confirm the tree is dead and provide written confirmation before the exemption applies. Do not assume: check with your council first.
What happens if my neighbour’s tree is overhanging my property?
The common law principle of abatement allows a property owner to cut back branches and roots that encroach from a neighbouring property, up to the boundary line. However, this does not permit removing the neighbouring tree, and any work should not cause the tree to become unstable or to die. Some Sydney councils have specific provisions about boundary trees. If the overhanging tree is causing damage or poses a risk, the best first step is a conversation with the neighbour and, if needed, advice from your council or a legal professional.
