Neighbour Tree Disputes in Queensland: Your Rights

Tree disputes between neighbours in Queensland are governed by the Neighbourhood Disputes (Dividing Fences and Trees) Act 2011. It sets out a defined process, and knowing that process is usually enough to resolve things well before anyone reaches a tribunal.

One thing to establish upfront, because it catches nearly everyone.

Two separate systems apply, and they do not override each other.

The Act governs what you can require of your neighbour. Your council’s vegetation protection governs whether the tree can lawfully be touched at all. If the tree is protected, a QCAT order does not make it removable without the council process — and neither of you can simply cut it down.

Who is responsible

The Act uses the term tree keeper — generally the owner of the land the tree is situated on. The tree keeper is responsible for cutting and removing branches that overhang, and for ensuring the tree does not cause serious injury, serious damage to property, or substantial ongoing unreasonable interference with the use and enjoyment of a neighbour’s land.

Your right to cut back

You may cut back branches overhanging your property to the boundary line, at your own cost, without asking permission.

That right comes with real limits:

• Only to the boundary — not past it, and not into the neighbour’s airspace
• Only what actually overhangs
• Only if the tree is not protected by your council — this is the constraint people miss
• You cannot enter your neighbour’s property to do it
• Severed material technically belongs to the tree keeper, though in practice most people dispose of it

That last point about protection matters. If the tree carries a Vegetation Protection Order, is a significant landscape tree, or sits within a protected area, cutting it back without a permit is an offence — regardless of whose side the branches are on.

The formal notice process

Where cutting back at your own cost is not reasonable — the branches are too high, the volume is unreasonable, or the problem is recurring — the Act provides a formal mechanism.

Step 1: Talk first

Genuinely. Most tree disputes are communication failures that hardened. A conversation before a notice costs nothing and preserves a relationship you may have for another twenty years.

Step 2: Serve a notice

You can serve a formal notice on the tree keeper requiring them to cut and remove the overhanging branches. The notice must meet the requirements set out in the Act, including giving the tree keeper a reasonable period to act.

If they do not comply within that period, you may be able to arrange the work yourself and recover reasonable costs from them, up to the limit the Act specifies.

Step 3: QCAT

If the notice process fails, or the issue goes beyond overhanging branches — serious damage, risk of serious injury, substantial interference — you can apply to the Queensland Civil and Administrative Tribunal.

QCAT can order the tree keeper to carry out work, to pay compensation, or in some cases to remove the tree.

My neighbour’s tree is damaging my property

Damage — as opposed to nuisance — changes what you can ask for. The Act lets QCAT order works, and it can order a neighbour to pay for rectification where their tree has caused or is likely to cause serious damage to your land or anything on it within the next twelve months.

The two situations that come up most:

Neighbours’ tree roots damaging my property

Roots lifting a driveway, cracking a slab, blocking a drain or displacing a retaining wall are all recognised. What carries the argument is establishing that the roots are in fact from that tree, and that the damage is serious rather than cosmetic — which usually means excavation to trace them rather than assumption.

Neighbours’ trees overhanging my property

Overhanging branches are ordinarily a nuisance rather than damage, and the self-help right in the section above usually resolves them. They become a damage question when a limb is likely to fail onto something of yours, which is a risk assessment rather than a pruning question.

In both cases the tree may also be protected under your council’s vegetation local law, which governs whether it can lawfully be touched at all — separately from what the Act entitles you to ask for.

Bamboo, palms, vines and hedges

The Act’s definition of a tree is far broader than the word suggests. Section 45 covers any woody perennial plant, any plant resembling a tree in form and size, and vines — and it prints bamboo, banana plant, palm and cactus as worked examples. A bare trunk, a stump rooted in the land and a dead tree are all included too.

That matters most for running bamboo, which spreads underground across boundaries and is the single most common dispute people wrongly assume the Act does not reach. It does, and the full process below applies to it. See Bamboo Disputes in Queensland for how the rules work when the problem is rhizomes rather than branches.

Section 44 also confirms that anything the Act allows for one tree can be done for two or more — so a hedge, a screen or a run of bamboo is dealt with as readily as a single specimen.

What QCAT actually decides

This is where an independent assessment earns its cost, because the tribunal is deciding questions of arboricultural fact:

• Is the tree likely to cause serious injury to a person?
• Is it likely to cause serious damage to land or property?
• Is it causing substantial, ongoing and unreasonable interference with the use and enjoyment of the land?
• What is a reasonable remedy — and is it proportionate?

Note what is not on that list. Leaf litter, shade, blocked views and general untidiness are, on their own, rarely sufficient. The Act sets a threshold, and “annoying” does not meet it.

Why an independent report matters

Both sides in a tree dispute tend to arrive convinced. The tribunal is not deciding whose account is more heartfelt — it is deciding arboricultural questions on evidence.

Once an application passes QCAT’s initial checks, the tribunal generally appoints its own tree assessor, with the parties sharing the cost up to $1,200, and after that report neither side can bring expert evidence on the same issues without the tribunal’s leave. So an independent report of your own is worth having earlier: before you apply, to find out whether you have a case, and for anything the assessor cannot see, such as roots under a slab.

It is worth being clear about what independence means in practice. A useful expert report is not an advocacy document. Its value comes precisely from the fact that it was not written to reach a predetermined conclusion — and sometimes that means telling the person paying for it that their position is weak. Knowing that before a hearing is considerably cheaper than discovering it during one.

If a tree falls and causes damage

A dispute about a standing tree and a claim about one that has already come down are different problems. Once a tree has fallen on a house, a car or a fence, the first questions are insurance ones — whose policy responds, what it covers, and whether the owner is liable at all. See A Tree Fell on My House: Who Pays in Queensland? for that sequence, including what to do in the first 24 hours and why the stump should not be ground out until somebody has looked at it.

The connection worth noting: if you warned your neighbour in writing about a tree before it fell, that warning becomes the most valuable evidence in the claim. The notice process described above is what creates it.

If your own tree was poisoned, cut or damaged

That is a different problem from a neighbour’s tree affecting you, and it sits outside the notice process above. The questions are what happened and what the tree was worth. See arborist expert witness reports for how poisoning, unauthorised removal and damage from building works are documented, and the tree valuation calculator for a first idea of the figure.

Practical sequence

1. Check the tree’s protection status with your council first. It constrains everything that follows.
2. Talk to your neighbour. Most of these end here.
3. Cut back to the boundary at your own cost if that resolves it and the tree is not protected.
4. Serve a formal notice under the Act if it does not.
5. Get an independent assessment before you apply, if you are not sure the case is there.
6. Apply to QCAT as the last step, not the first.

Steps one and two resolve the large majority of these. It is worth exhausting them properly before spending money on the rest.

The QCAT tree dispute guide and checklist sets out what to photograph and keep at each step, and what QCAT’s own tree assessor checks if it gets that far.
