Arborist reports in Melbourne: what's local
Banyule
Asks for an arborist report if 4 or more trees are involved, if any tree is on its significant tree register, or if the work is tied to a development.
Yarra Ranges
Wants a report if proposed work comes within 15 metres of a tree, or will remove, destroy or lop a protected tree. It should give each tree's dimensions, health, structure, tree protection zone and structural root zone, consistent with AS 4970:2025.
Glen Eira and Darebin
Glen Eira says reports should be prepared by suitably qualified AQF Level 5 arborists. Darebin asks for an AQF 5 report using an industry-recognised method for tree health, and a tree risk assessment for risk.
Kingston
Asks for a qualified arborist's risk assessment when the reason for removal is safety. For a tree on its significant tree register, the report must cover condition, reasons, alternatives, remedial action, the arborist's qualifications and a timetable.
Canopy tree applications
Under clause 52.37, removing or lopping a canopy tree for health or stability needs an assessment by a suitably qualified person. Knox and Monash both ask for that statement with the application.
Not every council
Boroondara's permit page doesn't require one: a council arborist inspects, and you can attach any expert reports you already have.
Building near trees in Melbourne
If you're building, subdividing or adding a unit, the report's job is to show which trees stay and how they'll be protected. AS 4970:2025 replaced the 2009 standard on 30 May 2025, and covers tree protection zones, structural root zones, impact assessments and tree protection plans. Older council documents may still quote the 2009 edition.
Councils differ on the process. Whitehorse points applicants to its guideline for arborist reports, known as an Arboricultural Impact Assessment. Maroondah suggests combining a tree removal application with the development application for two or more dwellings. Our tree protection zones guide explains the zones in plain English.

- Do you hold the Diploma of Arboriculture (AHC50524) or an earlier equivalent?

Hiring an arborist for a report in Melbourne
Read your council's checklist first, then brief the arborist with it, the site plan and any development drawings. A report written to the wrong scope gets sent back. If it's for a dispute or an appeal, say so up front, because the arborist will set it out differently.
