Managing Overhanging Branches Over Wollongong Fence Lines

Overhanging branches are among the most common neighbour concerns in the Illawarra. Wollongong's mild coastal climate, regular rainfall and fertile soils help trees grow quickly, and many suburbs, from Thirroul and Corrimal to Figtree, Dapto and Unanderra, have established gardens with large trees close to boundary fences. When limbs extend across a property line, they can cause damage, create safety risks and lead to disputes. This guide explains your rights, responsibilities and practical options for dealing with overhanging branches in Wollongong.

Understanding the Law on Overhanging Branches in NSW

In New South Wales, the rules about trees on boundaries are shaped by common law and the Trees (Disputes Between Neighbours) Act 2006. The Act gives the NSW Land and Environment Court the power to resolve disputes about trees on neighbouring land. It applies to Wollongong residential and certain other properties, and it is worth reading the current provisions before taking action.

The key principles are:

The tree belongs to the landowner where its trunk is planted. That owner is generally responsible for its maintenance and for damage it causes.
You may have a common law right to cut back branches that overhang your side of the boundary, but only up to the boundary line, and you must not trespass onto the neighbour's land to do so without permission.
Cut branches technically remain the neighbour's property. Offer to return them, or discuss disposal with the neighbour, rather than dumping them over the fence.
The Land and Environment Court can order tree removal or pruning where a tree has caused, or is likely to cause, injury or damage to property.
Council approval may still be required before you prune or remove certain trees, regardless of who owns them.

Check Wollongong City Council Requirements First

Before cutting anything, check whether Wollongong City Council regulations protect the tree. Under the council's development control plan and tree management provisions, some trees need a permit before pruning or removal. Protected trees can include significant species, trees in heritage conservation areas, trees in environmentally sensitive zones such as escarpment land, and vegetation covered by biodiversity or riparian controls.

Unauthorised pruning or removal of a protected tree can lead to substantial penalties. Contact Wollongong City Council or consult its current tree management guidance to confirm the status of the tree. A qualified arborist can also advise on whether a permit is needed and help prepare the application.

Why Overhanging Branches Matter

Property Damage

Branches that extend over fences can rest on or press against fence panels, causing sagging, rot and premature failure. In Wollongong's humid coastal conditions, constant leaf litter and moisture trapped against timber or Colorbond fences can speed up deterioration. Limbs can also damage roofs, gutters, sheds, pergolas and carports, and can block stormwater drainage.

Safety Risks

The Illawarra experiences strong southerly winds, east coast lows and heavy rainfall events. Weak, dead or poorly attached branches can fail in these conditions and fall into neighbouring yards. Branches close to power lines pose an additional hazard, and any work near powerlines should be carried out only by qualified, authorised personnel in line with Endeavour Energy requirements.

Bushfire and Pest Considerations

Properties near the escarpment and bushland edges may have additional bushfire management requirements. Overhanging branches that touch rooflines or sit close to buildings can increase fire risk. Dense overhanging foliage can also provide pathways for possums and rodents to access roof spaces.

Steps to Take When Branches Overhang Your Fence

Identify the tree and owner. Confirm where the trunk is located and whose land it sits on. If the trunk straddles the boundary, it may be jointly owned, and both owners may need to agree on any work.
Talk to your neighbour. A friendly conversation resolves most issues. Explain the concern, point out specific branches and suggest a timeframe for pruning. Many neighbours are unaware of the problem.
Follow up in writing. If a conversation does not work, send a polite letter or email describing the issue, including photos, and proposing a solution. Keep copies for your records.
Check council rules. Confirm whether the tree is protected and whether a permit is required.
Engage a qualified arborist. Have the work carried out to proper standards, particularly where branches are large, high or near structures or powerlines.
Consider mediation. If the neighbour will not cooperate, the Community Justice Centres in NSW offer free mediation services for neighbour disputes.
Apply to the Land and Environment Court as a last resort. Before applying, you generally need to have made reasonable attempts to resolve the matter with your neighbour.

Pruning Best Practice

How a tree is pruned affects its health and long-term safety. Poor cutting can leave a tree weakened, prone to disease or structurally unstable. Arborists in Australia follow Australian Standard AS 4373 Pruning of Amenity Trees, which sets out recommended practices.

Cut at the branch collar, the slightly swollen area where a branch joins a larger limb or trunk, rather than leaving stubs or cutting flush.
Avoid removing more than about 10 to 20 percent of a tree's canopy in one season, as heavy pruning can stress the tree and trigger weak regrowth.
Avoid "topping" or lopping, which creates unstable regrowth and can shorten a tree's life.
Use sharp, clean tools to reduce the spread of disease.
Prune large limbs using the three-cut method to prevent bark tearing.

Cutting a tree severely or in a way that kills it can create legal liability, even if the branches were overhanging your property. If your pruning damages the tree, the owner may seek compensation. Pruning back to the boundary line can also leave a lopsided tree, so professional advice is often worthwhile.

Common Wollongong Tree Species That Cause Overhang Problems

Certain species frequently cause boundary issues across the region:

Eucalypts and Corymbia species: Fast growing, with a tendency to drop limbs, particularly in storms.
Camphor laurel: Widespread in the Illawarra and capable of reaching large sizes. It is a declared weed in some areas, and council rules may differ from those for native trees.
Moreton Bay and Port Jackson figs: Large canopies and aggressive root systems that can affect fences and structures.
Jacarandas and liquidambars: Heavy leaf and flower litter that clogs gutters and collects along fence lines.
Bamboo and fast hedging plants: Can spread rapidly through and over fences if not managed.

Who Pays for Pruning?

Cost responsibility depends on the circumstances. If you choose to cut branches back to the boundary yourself under common law, you generally bear the cost. When a neighbour agrees to prune, costs are often shared or paid by the tree owner, particularly where the tree poses a hazard. Where the Land and Environment Court makes an order, it can specify who pays and how the work is carried out. Written agreements between neighbours help avoid confusion later.

Preventing Future Boundary Tree Problems

Plant new trees well back from fences, allowing for the species' mature height and canopy spread.
Choose species suited to smaller suburban blocks, particularly in newer subdivisions in areas such as Calderwood, Tallawarra and Haywards Bay.
Schedule regular inspections and pruning, ideally every one to three years depending on species and growth rate.
Keep gutters and fence lines clear of debris to reduce moisture damage.
Have storm-damaged or suspect trees assessed by an arborist before the next severe weather season.

When to Call a Professional Arborist

Hire a qualified arborist when branches are large, high above ground, near power lines or buildings, or when the tree may be protected. Look for professionals holding at least an AQF Level 3 qualification in arboriculture, appropriate public liability insurance and workers compensation cover. Written quotes should specify the scope of work, disposal arrangements and compliance with relevant standards. Insurance is especially important, as tree work is a high-risk activity and uninsured accidents can be costly for property owners.

Final Thoughts

Dealing with overhanging branches in Wollongong comes down to understanding your rights, communicating respectfully and following correct procedures. Start with a conversation, confirm council requirements, use qualified professionals and keep records of agreements and costs. Taking a cooperative, well-informed approach protects your fence and property, supports the health of established trees and helps maintain good relations with your neighbours in 2026 and beyond.
