AustraliaCan I claim for damage caused by a neighbor's tree roots in Australia?
Yes, you can claim for damage caused by a neighbour's tree roots in Australia under common law nuisance and state-based legislation, but you must prove causation and reasonableness.
What the Law Says
Australian law recognises that overhanging branches and invasive roots may constitute a private nuisance if they unreasonably interfere with your use or enjoyment of land.
Under common law, landowners have a duty not to allow natural features like trees to cause foreseeable harm to neighbouring properties. Courts assess whether the interference is substantial and unreasonable — not merely inconvenient. In New South Wales, the Trees (Disputes Between Neighbours) Act 2006 provides a statutory framework specifically for tree-related disputes, including root damage, but excludes certain tree types like fruit trees on residential land.
Victoria relies on the common law of nuisance and the Catchment and Land Protection Act 1994 for invasive species control, while Queensland applies the Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 — which explicitly covers root damage affecting foundations, pipes or drains. You must prove the roots originated from the neighbour’s tree and directly caused quantifiable damage (e.g., cracked footings, blocked sewer lines), supported by arborist and structural engineer reports.
Courts consider factors such as the tree’s age, species, proximity to structures, and whether the neighbour knew or ought to have known about the risk. In the landmark case Yannopoulos v Katsoulis [2013] NSWCA 7, the NSW Court of Appeal confirmed that mere encroachment of roots without proven damage does not sustain a nuisance claim.
Statutory TextA person may apply to the Local Court for an order in relation to a tree if the tree causes, or is likely to cause, damage to the applicant’s property.

What to Do
Document the damage thoroughly with dated photos, videos, and written notes; retain all repair quotes and expert reports (e.g., arborist, plumber, structural engineer).
Speak with your neighbour informally first — many disputes resolve amicably when evidence is shared and responsibilities clarified.
Send a formal written notice outlining the issue, requesting action (e.g., root pruning or removal) within a reasonable timeframe (typically 14–30 days). Keep a copy.
If unresolved, lodge an application with your state’s appropriate tribunal or court: e.g., NSW Local Court (under the Trees Act), QCAT in Queensland, or VCAT in Victoria.
If successful, orders may include trimming, removal, cost reimbursement (up to $5,000 in NSW Local Court), or compensation for proven losses — but not for purely aesthetic concerns or speculative future damage.
