If you want to remove a protected tree on your property, your local council will almost certainly require an arborist report as part of the application. Understanding the requirements upfront saves time, money, and frustration.
Why Councils Require Arborist Reports
Councils use arborist reports to make objective decisions about tree removal applications. The report provides an independent professional assessment of whether removal is justified on grounds such as poor health, structural failure risk, infrastructure damage, or safety concerns. Without a report, the council has no basis for evaluating your application.
What the Report Must Include
While requirements vary between councils, most expect the arborist report to include the following:
- Tree species, dimensions (height, canopy spread, trunk diameter), and estimated age
- Health assessment including vigour, foliage density, and disease or pest presence
- Structural assessment identifying defects, decay, lean, and root damage
- Risk rating using a recognised methodology such as QTRA or TRAQ
- Clear photographs of the tree and any defects
- Site plan showing the tree’s location relative to structures
- Professional recommendation with justification for removal, retention, or pruning
The Application Process
Step 1: Check Your Council’s Rules
Start by checking your council’s website or calling their planning department to confirm whether the tree is protected and what documentation is required. Our council tree removal guide covers the general process across Australian councils.
Step 2: Engage a Qualified Arborist
Hire an arborist with at least an AQF Level 5 Diploma of Arboriculture. Some councils specify the minimum qualification required, so check before you book. The arborist will visit your property, assess the tree, and prepare the written report.
Step 3: Submit Your Application
Lodge the arborist report along with your tree removal application form and any applicable fees. Processing times vary from two weeks to three months depending on the council and complexity.
Common Reasons Applications Are Approved
Councils are most likely to approve removal when the arborist report demonstrates genuine safety risk, significant structural decline, root damage to infrastructure, or the tree is an inappropriate species for the location.

Tips for a Smooth Application
- Choose an arborist familiar with your specific council’s requirements
- Provide honest context to the arborist rather than trying to influence the outcome
- Submit a complete application the first time to avoid delays
- Be prepared to accept conditions such as replacement planting
