If the tree is protected under Brisbane City Council’s Natural Assets Local Law 2003, you’ll need a permit to remove it, and in many cases an AQF Level 5 arborist report to support that application. If the tree isn’t protected and sits inside your own boundary, you usually don’t need either.
Working out which side of that line your tree falls on is the first job. Here’s how the process actually runs.
When Does the Council Require an Arborist Report?
The permit itself is free. The report is what costs money, and Council asks for one in specific situations rather than for every application.
| Situation | What’s usually required |
| Removing or pruning a significant landscape tree | AQF Level 5 arborist report |
| Building or working within the root zone of a significant landscape tree | AQF Level 5 arborist report |
| Construction that may impact the root zone of protected vegetation | Arboricultural Impact Assessment |
| Removing a protected tree on hazard or health grounds | Arborist report or tree risk assessment |
| Tree removal as part of a development application | Arboricultural Impact Assessment, often with a tree protection plan |
| Ongoing maintenance of protected vegetation | Protected Vegetation Management Plan for a long-term permit |
Council may also ask for a tree risk assessment report alongside the arborist report, depending on what you’ve applied to do. If you aren’t sure which applies to your situation, Council’s protected vegetation permits page sets out the full list of supporting documents.
When Don’t You Need a Permit?
Some work on protected vegetation is exempt, but the exemptions only apply inside your own property boundaries. They do not cover:
- Trees or vegetation on Council land
- Work on a property you don’t own
- Pruning, removing or building within the root zone of a significant landscape tree
- Construction next to or underneath the canopy of protected vegetation
- Vegetation protected by anything other than NALL, including heritage trees, tidal vegetation, statutory covenants and conditions of a development approval
Removing protected vegetation without permission is an offence even on your own land, and penalties run from infringement notices through to prosecution. If you aren’t certain whether your tree is protected, check before booking any work.
Why Does It Have to Be an AQF Level 5 Arborist?
Not every arborist can write a report Council will accept. The Australian Qualifications Framework separates practical tree work from consulting work.
| Level | What they do |
| AQF Level 3 | Practical tree work. Climbing, pruning, removals |
| AQF Level 4 | Supervises tree work and advises on pruning and maintenance |
| AQF Level 5 | Consulting level. Assesses trees and writes reports for councils and development applications |
A Level 3 arborist can take your tree down safely. Only a Level 5 consulting arborist can produce the assessment Council relies on to approve it. If you’re quoted a cheap report, confirm the qualification before you pay for something the Council won’t accept.
Our consulting arborist team handles assessments and Council reporting, separate from the crews who carry out the work.
What’s Inside an Arborist Report?
A report for a removal application is a technical document, not a letter of opinion. Expect it to cover:
- Botanical and common name of each tree, plus its dimensions and estimated age
- Health and structural condition, assessed from the ground
- Identified defects such as decay, cavities, included bark, deadwood or root damage
- Risk rating, usually using a recognised method like TRAQ or QTRA
- Site context, including proximity to buildings, services, fences and boundaries
- Recommended action, which may be removal, pruning, cabling, or monitoring rather than removal
- Photographs and a site plan showing tree locations
- The arborist’s qualifications and declaration
A good report doesn’t just say the tree should go. It documents why, in terms Council can assess against the local law.
What About Reports for Development Applications?
Development work follows a different path. Where construction could affect protected vegetation, Council wants an Arboricultural Impact Assessment rather than a straightforward removal report.
An AIA maps out which trees are affected, calculates tree protection zones and structural root zones under AS 4970, and shows how the build works around retained trees. It often comes with a tree protection plan setting out fencing, ground protection and supervision during construction.
Two things to know if you’re developing:
- Get the assessment done early. Trees identified late can force redesign after you’ve paid for plans.
- Approved DAs often carry conditions requiring a project arborist to inspect and certify at set stages. That’s ongoing work, not a one-off report.
What Do Arborist Reports Cost in Brisbane?
Most residential reports for a single tree or a small group fall between $400 and $800 plus GST. What moves the price:
| Factor | Effect |
| Number of trees | Per-tree cost drops across a larger assessment |
| Report type | An AIA for a development costs more than a single-tree removal report |
| Site complexity | Steep blocks, multiple boundaries and heritage overlays add time |
| Diagnostic testing | Decay detection or soil testing is quoted on top |
| Turnaround | Urgent reports often carry a premium |
The permit itself costs nothing, so the report and any testing are your only real outlay in the application stage.
How Long Does the Whole Process Take?
| Stage | Typical timeframe |
| Site inspection booked | A few days |
| Report written and delivered | 2 to 5 business days after inspection |
| Council response to a permit application | Within 20 business days |
| Minor street tree pruning permit | Issued immediately |
Plan on several weeks end to end for a protected tree, longer if Council asks for additional information. This matters when settlement dates or build schedules are involved.
Genuinely dangerous trees are a different situation. If a tree has failed or is failing right now, that becomes an emergency response rather than a permit process.
What Makes an Application More Likely to Be Approved?
Council assesses your application against the local law, and lodging one doesn’t guarantee approval. Applications tend to succeed when the report clearly establishes that the tree:
- Poses a genuine, documented risk to people or structures
- Is dead, dying, or in irreversible decline
- Is a declared invasive species
- Conflicts with an approved development
Weak applications usually fail on evidence rather than merit. Vague statements about a tree being messy, dropping leaves, or blocking a view rarely get anywhere. Photographs of actual defects, measurements, and a clear risk rating do the work.
It’s also worth accepting that a proper assessment sometimes recommends keeping the tree. Selective pruning, crown reduction or root zone management can resolve many problems without removal, and our tree lopping and pruning crews handle that work once the report sets the scope.
What Happens After Approval?
Once a permit is granted, the work has to be done to the standards and conditions on it. You then complete a Declaration of Compliance confirming the works are finished, whether they met the permit conditions, and details of any replacement planting, including photos and a location sketch. It’s due by the date on your permit.
Replacement planting is a common condition, so factor it into your plans rather than treating it as optional. Once the tree is down, stump grinding clears the ground for whatever comes next.
Getting a Report Started
Have the property address, a description of the tree or trees, and photos ready. That’s usually enough for a consulting arborist to tell you whether the tree looks protected and what type of report your situation needs.

Frequently Asked Questions
Protection depends on species, size, location, and any overlays on your property, and it isn’t obvious from looking at the tree. The council can confirm your situation by phone, and a consulting arborist can review your address and overlays before you commit to a full report.
No. Reports supporting work on a significant landscape tree need to come from an AQF Level 5 arborist. A Level 3 or Level 4 qualification covers the physical work but not the consulting assessment.
No. The report is evidence, not a decision. Council assesses each application against the Natural Assets Local Law, and lodging an application does not guarantee a permit.
Often yes, if it’s protected. Council will consider the removal of a dead or dying protected tree, but you still need the condition documented and a permit issued before work starts.
An arborist report assesses the condition of existing trees and recommends action. An AIA assesses how proposed construction will affect trees, calculates protection zones, and sets out how retained trees are to be protected during the build.
