One of the most common questions we get from Canberra homeowners is whether they need permission before removing a tree on their own property. You might assume that because the tree is on your block, you can do what you like with it. In the ACT, that is not always the case — and getting it wrong can be expensive.
The short answer is: it depends on the tree. The ACT has specific tree protection legislation that covers certain trees, and removing a protected tree without approval can result in significant fines. Whether you are planning a renovation, dealing with a hazardous limb, or clearing space for a new driveway, understanding the rules before you pick up a chainsaw is essential.
Here is a practical guide to ACT tree removal approval — what is protected, when you need permission, how to apply, and what happens if you skip the process.
What Trees Are Protected in the ACT?
Under the ACT's Urban Forest Act 2023, a tree is considered "regulated" if it meets certain size thresholds. The key criteria are:
- Trunk circumference of 1 metre (100 cm) or more, measured at 1.4 metres above natural ground level
- Height of 8 metres or more
- Canopy width of 8 metres or more
Additionally, dead native trees with a trunk circumference of 1.88 metres or more at 1.4 metres above natural ground level are also protected, as they provide essential habitat for local fauna.
Any tree that meets even one of these criteria is considered a protected tree under ACT law. That means a relatively modest tree in your front yard could be protected if it has reached a certain size — even if it is causing problems with your pipes, shading your solar panels, or dropping branches onto the driveway.
Note: Some trees are also listed on the ACT Tree Register as significant trees. These receive additional protection regardless of size. A registered tree might be a landmark specimen, a rare species, or a tree with cultural or heritage value. If your tree is on the register, removal approval is required no matter how small it is.
Not sure whether your tree qualifies? A qualified arborist can measure the trunk, assess the canopy spread, and check whether the tree appears on the register — all as part of a free on-site quote for tree removal in Canberra.
When Do You Need Approval?
You need approval from the ACT Government through Transport Canberra and City Services (TCCS) if:
- The tree is a regulated tree that meets the size criteria above
- The tree is listed on the ACT Tree Register
- The tree is on leased land — and most residential blocks in the ACT are leasehold, not freehold
In practice, this means the majority of established trees on Canberra residential blocks require some form of approval before removal. TCCS assesses applications on a case-by-case basis, considering the tree's health, species, location, and the reason you want it removed.
Common grounds for approval include trees that are dead, dying, or structurally unsound; trees causing documented damage to infrastructure such as pipes, foundations, or driveways; trees posing a genuine safety risk to people or property; and trees that must be removed as a condition of development approval. Simply not liking a tree's appearance or wanting a better view is rarely sufficient on its own — though an arborist report documenting structural issues can strengthen a marginal case.
If you are clearing multiple trees for a building project or subdivision, you may also need to factor in separate land clearing requirements alongside individual tree removal approvals.
When Don't You Need Approval?
There are exemptions, and understanding them can save you time — but only if you are confident the exemption genuinely applies to your situation. You generally do not need approval for:
- Trees below the regulated size thresholds — small ornamental trees, young plantings, and saplings that have not yet reached the circumference, height, or canopy criteria
- Dead trees — though you may still need to notify TCCS, and you should have an arborist confirm the tree is genuinely dead rather than dormant (deciduous trees in winter can look dead when they are simply leafless)
- Some pest species and declared weeds — certain invasive species are exempt because removing them supports local ecology rather than harming it
- Emergency situations — where a tree poses an immediate danger to life or property, you may remove it without prior approval, but you should notify TCCS as soon as practical and document the hazard. Our 24/7 emergency tree service can attend urgent situations and provide the documentation you need
The emergency exemption is not a free pass for convenience. If TCCS investigates and finds the tree was not an immediate hazard, you could still face penalties. When in doubt, get professional advice before cutting.
What About Queanbeyan and NSW Areas?
Canberra's tree laws do not extend beyond the ACT border. Queanbeyan, Bungendore, Bywong, Carwoola, Gundaroo, Yass, and other surrounding areas fall under NSW local council regulations rather than ACT legislation. The rules vary significantly between councils — some require development applications for trees above a certain height or trunk diameter, while others have tree preservation orders covering specific species or locations.
If you live just across the border, do not assume ACT rules apply. Queanbeyan-Palerang Regional Council, Yass Valley Council, and other local authorities each have their own processes. In general, NSW councils regulate trees above a certain size and may require a permit or development application for removal, particularly on urban blocks or in heritage areas.
We service both ACT and NSW properties regularly. During a free on-site assessment, we can advise which jurisdiction applies to your property and what approvals you may need. See our full coverage across areas we serve, including dedicated pages for Queanbeyan and Bungendore.
How Do You Apply for Approval?
The ACT approval process typically involves four steps:
- Submit an application to TCCS — include details about the tree (species, location, size), photographs, and your reasons for wanting it removed
- Assessment by a government tree officer — TCCS may inspect the tree on-site or review your documentation
- A decision — approval (possibly with conditions such as planting a replacement tree), or refusal with reasons
- Timeframe — allow several weeks for processing; straightforward applications with supporting arborist reports tend to move faster
Gathering strong supporting evidence makes a real difference. Photographs showing structural damage, reports from a plumber confirming root intrusion into pipes, or an arborist assessment documenting decay all strengthen your application. Vague statements like "the tree is too big" without supporting detail are less likely to succeed.
If approval is granted with a replanting condition, factor that into your landscaping plans. Replacement trees must usually meet minimum size requirements at planting and may need to be a native or approved species.
Can an Arborist Help with the Application?
Yes — and in many cases, an arborist report is the difference between approval and refusal. We can provide a professional assessment documenting the tree's species, age, condition, structural integrity, and the specific reasons removal is recommended. This might include evidence of internal decay, root damage to infrastructure, crown dieback, or a lean that indicates root failure.
An arborist report gives TCCS an independent, expert opinion rather than relying solely on the property owner's description. It demonstrates you have taken the matter seriously and sought qualified advice before applying. We prepare these reports regularly for Canberra homeowners and can walk you through exactly what TCCS expects.
We can also advise whether removal is genuinely necessary or whether pruning or treatment might address your concerns — saving you the approval process entirely if the tree can be retained safely.
What Happens If You Remove a Tree Without Approval?
Removing a protected tree without approval is an offence under ACT law. Fines can be substantial — potentially thousands of dollars per tree — and you may also be required to plant replacement trees at your own expense. TCCS can investigate reports from neighbours, aerial imagery, or routine inspections, and penalties are not limited to the person who physically cut the tree; the property owner or leaseholder is typically held responsible.
It is not worth the risk. Even if you think nobody will notice, stump removal, changed garden layouts, and satellite imagery make unauthorised removals relatively easy to detect. If you are unsure whether your tree is regulated, get professional advice before you start. Read our guide on when to remove a tree if you are still deciding whether removal is the right option.
Frequently Asked Questions
Is a dead tree still regulated?
Generally, dead trees are exempt from the approval requirement, but you should still check with TCCS or get an arborist to confirm the tree is dead rather than dormant — especially for deciduous species in winter. A tree that appears dead in June may leaf out again in October.
How long does the approval process take?
In the ACT, allow 4–8 weeks from application to decision. Straightforward cases with a supporting arborist report tend to be processed faster. Complex applications involving registered trees or development conditions may take longer.
Do you handle the application for me?
We can prepare the arborist report and guide you through the application process step by step. The formal application itself is submitted by the property owner or leaseholder, as TCCS requires the landholder to be the applicant.
What about trees on the nature strip?
Trees on the nature strip (the verge between your property boundary and the road) are ACT Government property. You cannot remove or prune them without government authorisation. If a nature strip tree is causing problems — blocking sight lines, dropping limbs, or damaging the footpath — contact TCCS directly to report the issue.
