An arborist report is a professional assessment of a tree’s health, structure, and risk level, prepared by a qualified arborist. If your council requires one before you can remove or prune a tree, understanding the cost upfront helps you budget for the full project.
Arborist Report Pricing in 2026
The cost of an arborist report depends on the type of assessment, the number of trees, and the complexity of the situation. Here are the typical price ranges:
- Basic tree assessment (single tree): $300 – $500
- Standard arborist report for council: $400 – $800
- Multi-tree assessment (development site): $800 – $2,000
- Detailed risk assessment: $600 – $1,200
- Level 5 arborist report (expert witness): $1,500 – $5,000+
What Is Included in an Arborist Report?
A standard arborist report service typically includes a site visit, visual tree assessment, species identification, health and structural evaluation, risk rating, and written recommendations. The report may also include photographs, a site plan, and references to relevant Australian Standards such as AS 4970 (Protection of Trees on Development Sites).
Factors That Affect Report Cost
The number of trees being assessed is the biggest cost factor. A report covering a single backyard tree is straightforward, while a development site with 30 trees requires significantly more time. Urgency also matters. If you need a report within 48 hours rather than the standard two-week turnaround, expect to pay a premium of 25-50%.
When Do You Need an Arborist Report?
Most councils require an arborist report when you apply to remove a tree that is protected under local planning rules. You may also need one for development applications, insurance claims, neighbour disputes, or when assessing trees after storm damage. Our complete arborist report guide explains each scenario in detail.
How to Save on Arborist Report Costs
- Get multiple trees assessed in a single visit rather than separately
- Provide clear site access so the arborist spends less time on logistics
- Ask whether the arborist who writes the report can also do the removal work
- Check if your council actually requires a formal report or just a letter from a qualified arborist
