If a council planner, a builder or a neighbour has mentioned you might need an arborist report, you are probably wondering what it actually is and whether you genuinely need one. The short version: an arborist report is a professional assessment of a tree’s health, structure and significance, and in Melbourne you most often need one when you want to remove or prune a protected tree, or when you are building near one. But you do not need one for every tree or every job. This article explains when a permit is generally required, which exemptions exist, why some non-native trees can still be protected, and, most importantly, why the council is the one that decides whether any of it applies to your block. The Yard handles land clearing and tree removal across Victoria, and this guide is general information, not planning advice, so your council is always the place to confirm.
What an arborist report actually is
An arborist report is a document prepared by a qualified arborist that assesses a tree and sets out professional findings about it. Rather than a simple opinion, it is a structured assessment, and councils rely on it to make decisions about trees on private and public land.
Depending on why it is needed, a report typically covers things such as the tree’s species, its size and age, its health and structural condition, whether it poses any risk, its significance or value, and what impact a proposed activity, such as building work or removal, would have on it. Where removal or pruning is proposed, the report sets out the reasoning and often recommends how the work should be carried out or what protection a retained tree needs.
The reason councils ask for these is that they need an independent, qualified basis for a decision about a tree, rather than taking the word of whoever wants it removed. A report from someone with the right credentials gives them that. At The Yard, our assessments are backed by over 10 years of certified arboriculture and regulatory experience and comply with the Australian arboriculture standards set by Standards Australia EV-018, which is the standard of assessment councils are looking for.
When your council will ask for one
The most common trigger for needing an arborist report in Melbourne is wanting to do something to a protected tree. Many Melbourne councils protect trees through planning controls such as significant landscape overlays, environmental overlays, vegetation protection overlays, or local laws, and these can apply to a tree based on its size, species, location or significance.
You will generally need a report in situations like these:
- Removing or pruning a protected tree. If a tree is covered by a council overlay or local law, you usually need a permit to remove or prune it, and the council will commonly require an arborist report to support that permit application.
- Building or developing near a tree. When you are building, extending or developing close to a tree that is being retained, the council often wants a report assessing how the work will affect the tree and what protection it needs during construction.
- A tree in poor health or posing a risk. If a tree is declining, damaged or potentially dangerous, a report assesses its condition and whether removal is justified, which the council uses to decide on a permit.
- A planning application that involves trees. Larger planning and subdivision applications frequently require an arborist report as part of the documentation where trees are present on or near the site.
In each of these, the report is what gives the council the independent assessment it needs to say yes or no. The one constant is that the council decides whether a report is required and whether the permit is granted, so your council is always the place to confirm what your specific situation needs.
When you probably do not need one
Just as useful is knowing when a report is not required, so you are not paying for one unnecessarily. You generally do not need an arborist report when the tree is not protected and your proposed work does not trigger any council control.
That tends to cover situations such as a tree that is not covered by any overlay or local law, a tree below the size threshold a council sets for protection, or certain exempt species or circumstances. Routine maintenance that does not require a permit, such as minor pruning within what a council allows, also usually does not need a report. The catch, and it is an important one, is that you cannot reliably judge for yourself whether a tree is unprotected, because the controls vary between councils and depend on the specific overlay, the species and the location. A tree that looks ordinary can still sit under a protection control.
So even when you suspect you do not need a report, the safe move is to confirm it with your council first rather than assume. A quick check protects you from removing a tree that turned out to be protected, which is a serious matter regardless of whether you knew.
How it connects to clearing native vegetation
Arborist reports sit alongside a separate but related set of rules in Victoria: the protection of native vegetation. If the tree you are dealing with is native vegetation, there is a whole additional framework that can require a planning permit to remove it, over and above any council tree control.
The two systems can both apply to the same tree, which catches people out. A native tree might be protected under a council overlay (where an arborist report comes in) and also be subject to the state’s native vegetation rules at the same time. Victoria publishes guidance on when a permit is needed to remove native vegetation and on the exemptions that can apply, which you can read through the Victorian Government’s native vegetation guidance and its list of exemptions from requiring a permit.
As with everything here, whether a native vegetation permit is required, and whether any exemption applies to your block, is determined by the council, not by you. So if there is any chance the tree is native vegetation, that is another reason to confirm the full picture with your council before doing anything.
Getting it right the first time
The sensible order is to sort out the assessment and the approvals before any work happens, not after. Start by contacting your council to find out whether the tree is protected, whether you need a permit, and whether an arborist report is required to support it. If a report is needed, having it prepared properly, by someone with the right credentials and to the right standard, is what gives your application the best footing. As a Licensed Tree Removal Specialist, The Yard can assess the tree, prepare the report the council is after, and carry out the work once approval is in place, so the whole thing is handled end to end.
Doing it in that order- confirm, assess, approve, then act- is what keeps a tree job straightforward rather than turning it into a compliance problem.
Frequently Asked Questions
What does an arborist report include?
It typically covers the tree’s species, size, age, health and structural condition, any risk it poses, its significance, and the impact of proposed work such as removal or building nearby. The exact contents depend on why the report is needed and what your council requires.
Does every tree removal need an arborist report?
No. A report is generally needed when a tree is protected by a council overlay or local law, or when building near a retained tree. An unprotected tree outside any control often does not need one, but your council confirms whether yours does.
Who decides if I need a permit or a report?
Your local council. They determine whether a tree is protected, whether a permit is required to remove or prune it, and whether an arborist report must support the application. Because the rules vary between councils, confirming with yours is essential before any work.
Can one report cover council rules and native vegetation rules?
A report assesses the tree, but council tree controls and Victoria’s native vegetation rules are separate frameworks that can both apply. The council determines what each requires, so confirm both with them rather than assuming one report or approval covers everything.
Check before you cut
An arborist report is the professional assessment councils rely on to decide about a tree, and in Melbourne you most often need one to remove or prune a protected tree or to build near one, while an unprotected tree outside any control usually does not require one. The deciding factor is always the council, so the first step for any tree job is to confirm with them what your situation needs. If you would like the tree assessed and the report prepared properly, contact The Yard, Unit 2/42 Ravenhall Way, Ravenhall VIC 3023, on 0450 410 800.
