What Is an Arborist Report?
Types of Arborist Reports
There isn’t one standard arborist report — the type you need depends on your situation. A DA arborist report is the most common type, required when applying to council for permission to remove, prune, or work near a protected tree. A tree removal report specifically documents the justification for removing a tree due to disease, structural failure, safety risk, or development impact. An Arboricultural Impact Assessment (AIA) is required for development projects where construction activity will occur near existing trees. A Tree Protection Plan specifies the physical measures to protect retained trees during construction. A Tree Risk Assessment uses a standardised methodology to assign a risk rating. A pre-purchase tree inspection identifies trees that pose a risk and any council protection implications before you buy.
What Does a Good Arborist Report Include?
Regardless of the type, a professional arborist report should include site and tree identification covering species, location, and dimensions; health and condition assessment covering vigour, structural integrity, and pest or disease status; risk evaluation covering likelihood of failure and recommended actions; photographic documentation supporting the findings; clear specific recommendations proportionate to the findings; and the arborist’s credentials including name, qualifications, and AQF level. Reports that lack photographic evidence, use vague language, or don’t identify the author’s qualifications are red flags and are often rejected by councils.

Do You Need an Independent Arborist Report?
If your tree removal company is offering to prepare your arborist report for free as part of a removal quote, be cautious. There is an inherent conflict of interest when the same party assessing the tree also profits from its removal. Councils are increasingly scrutinising reports prepared by removal companies, and some LGAs in Sydney now specifically require reports to be prepared by an independent consultant — one with no financial interest in the outcome. At Arbor Metro we operate exclusively as independent consultants. We don’t perform tree removals and our reports reflect what we find, not what any particular outcome would mean for our bottom line.
Frequently Asked Questions
What is an arborist report used for? Arborist reports are used to support council applications, justify tree removal, satisfy development approval conditions, assess risk for insurance purposes, and inform property purchasing decisions. How long does an arborist report take? Most standard reports can be completed within 3–7 business days of the site inspection. Does my council require an arborist report to remove a tree? In most Sydney LGAs yes, if the tree is protected under council controls. How do I know if an arborist is qualified? Look for a Consulting Arborist at AQF Level 5 for reports and assessments. Ask for their qualification certificate if in doubt.
