Tree Health Assessment Sydney

Common warning signs are a thinning canopy, dead branches in the upper crown, leaves browning or dropping out of season, bark falling away in sheets, fungal brackets or mushrooms at the base, and soil lifting near the roots. One sign on its own rarely settles it, which is why an on-site assessment looks at the whole tree and its root zone before anyone talks about removal.

An AQF Level 5 arborist walks the whole tree from the root zone up: soil and root-crown condition, trunk defects such as cracks, cavities and fungal fruiting bodies, branch unions, deadwood, canopy density and pest or disease activity, plus what the tree could hit if something fails. You get the findings explained on site in plain English, with a practical next step.

No. A health assessment is practical on-site advice about the tree itself. An arborist report is a formal written document for a council application, development approval or dispute, and many Sydney councils, including North Sydney and Ku-ring-gai, only accept reports from an AQF Level 5 consulting arborist. If you need the paperwork, we write those too — see our arborist reports page.

The visit is quoted up front once we have seen photos of the tree and the access — no call-out fee, and quotes for any tree work that follows are free. If a council or development application needs a formal written report, an AQF Level 5 arborist report is $1,500–$2,000 ex GST.

Fungal fruiting bodies at the base are worth taking seriously. The Botanic Gardens of Sydney lists Ganoderma brackets — found near the base of living trees, often at an old wound — as a decayer of sapwood and heartwood in roots, butts and trunks, and Armillaria as a soilborne fungus causing root rot and wood decay. Neither automatically means removal, but both mean the tree should be assessed.

Browning sections in exotic conifers such as Leyland cypress are often cypress canker, which the Botanic Gardens of Sydney describes as a serious disease of exotic conifers in Australia — it interferes with sap flow and kills the branch or trunk above the infected wound. Pruning out infected limbs early can slow it; badly affected trees are usually removed.

Myrtle rust is a fungal disease that infects plants in the Myrtaceae family — lilly pillies, bottlebrush, paperbarks, tea trees and eucalypts among them. NSW DPI describes infection starting as small purple spots on leaves that develop bright yellow spore pustules, on soft new growth. If you see it, do not prune it yourself — disturbing the pustules spreads the spores.

Often, yes. The assessment tells you which path fits: targeted pruning, root-zone repair, pest treatment, or monitoring and re-checking. Removal is only recommended when decay or structural defects make the tree a genuine risk to people or property.

Usually yes — a declining or even dead tree is still protected in most Sydney council areas. The rules differ: Georges River allows removal of an imminently dangerous tree assessed by an AQF Level 5 arborist with an exempt-works form lodged within 72 hours, while Ku-ring-gai requires the council itself to confirm a dead tree in writing before any work. We check your council's rules as part of the assessment.

For formal reports, councils set the bar: North Sydney Council, for example, only accepts reports from consulting arborists holding an AQF Level 5 qualification (Diploma of Arboriculture or equivalent). True Roots assessments are done by an AQF Level 5 arborist with about 15 years in arboriculture, so the person looking at your tree is qualified to write the council report if it turns out you need one.

As a working rule: after any major storm, before you buy a property with large trees, when you are planning building work near a tree, and every year or two for big, older trees close to houses, driveways or play areas. Small garden trees away from targets rarely need a schedule.

It depends on the circumstances, and no web page can settle liability for you. What helps either way is documented evidence of the tree's condition. In NSW, tree disputes between neighbours are heard by the Land and Environment Court under the Trees (Disputes Between Neighbours) Act 2006, which lets the court remedy, restrain or prevent damage or injury caused by a tree. An assessment, with photos, is the sensible first step.

The NSW RFS 10/50 scheme only applies on land inside a designated 10/50 entitlement area — not all bushfire-prone land qualifies. There, eligible owners can clear trees within 10 metres of a home without a permit, subject to the RFS code of practice. Check the address on the RFS online tool on the day you clear. Our 10/50 guide explains it step by step.
