What Happens to a Tree Report After You Submit It to Council in Melbourne?

Most people put significant effort into getting an arborist report prepared, and then assume the hard work is done once it lands on a council officer's desk. That assumption is where projects often run into trouble. Understanding what happens after submission is just as important as understanding what goes into the report itself, and in many cases it directly affects how long your permit takes and whether it gets approved at all.

This article walks through the post-submission process so you know what to expect, what councils are actually doing with your documentation, and how to avoid common delays that push timelines out by weeks or months.

How Council Receives and Reviews a Tree Report

When a planning application is lodged in Melbourne, any supporting arborist report or tree assessment report is reviewed as part of the broader documentation package. Council planning officers assess whether the report meets the minimum technical standards required under the relevant planning scheme, which in 2026 includes the reformed Clause 52.37 provisions that have strengthened canopy protection obligations across most metropolitan municipalities.

The officer reviewing your application is not always an arboricultural specialist. In many cases, they are a general planning officer who will refer the tree report to a council arborist or an independent assessor if the documentation involves significant trees, heritage overlays, or contentious removal justifications. That referral adds time to the process, and the quality of the report submitted determines how much scrutiny it attracts at that stage.

A well structured report prepared to Australian Standard AS 4970 with clear tree protection zone calculations, condition ratings, and retention recommendations reduces the likelihood of referral queries. A poorly structured report, or one that does not directly address the planning controls triggered by the application, almost guarantees them.

What Council Is Actually Looking For

Council officers are not reading an arborist report to learn about trees. They are checking whether the documentation justifies what the application is proposing to do near, around, or to protected vegetation.

The core questions they are working through include whether the report identifies all significant trees on and adjacent to the site, whether the tree protection zones have been calculated correctly, whether the proposed works intrude into those zones and if so whether the report adequately justifies that intrusion, and whether the recommendations are practical and enforceable as permit conditions.

If the report supports a development that removes or significantly impacts a significant tree, council will scrutinise the justification closely. If the report recommends retention with conditions, council will assess whether those conditions are specific enough to be applied as enforceable planning permit conditions. Vague recommendations create problems here. Statements like "care should be taken near tree roots" carry no weight at this stage. What council needs is measurable, site-specific guidance tied to construction methodology.

Our tree reports are structured around council expectations from the outset, which is why they tend to move through the assessment stage without generating significant officer queries.

Referral Agencies and Independent Assessment

Depending on the municipality and the nature of the application, your tree report may be referred to a third party for independent review. This is more common on applications involving heritage listed trees, applications within Significant Landscape Overlays, or projects where the proposed works are close to or within the tree protection zone of a large or high-retention-value tree.

Independent assessors appointed by council will review the original report against AS 4970 benchmarks and may conduct their own site inspection. If their findings differ from the submitted report, council will generally defer to the independent assessment. This is one of the primary reasons the qualifications and methodology of the original consultant matter. A report prepared by a consultant holding AQF Level 5 arboriculture qualifications using a recognised visual tree assessment methodology is far harder to challenge than one that lacks clear methodological documentation.

Because Arborplan operates solely as a consultancy with no commercial interest in tree removal or pruning outcomes, our assessments are positioned as genuinely independent. That independence holds up under referral review in a way that reports from contractors with a financial stake in the outcome often do not.

When Council Requests Additional Information

A request for further information, commonly referred to as an RFI, is one of the most common causes of permit delays in Melbourne. An RFI stops the statutory clock on a planning application and gives the applicant a set period to respond. If the RFI relates to the tree report, the consultant who prepared the original report typically needs to provide a written response, supplementary documentation, or in some cases a revised report.

The most common tree related RFI triggers include insufficient detail on tree protection zone management during construction, no arboricultural method statement for works within the TPZ, unclear tree condition ratings or retention recommendations, and reports that do not address all trees within the zone of influence of the proposed works.

Responding to an RFI is not simply a matter of answering a few questions. A strong response needs to directly address each officer query with technical specificity. A weak or incomplete response will not close out the RFI and will result in further delays.

If your project involves non-destructive root investigation, the data gathered during that process often becomes critical evidence when responding to council queries about subsurface root architecture and construction risk.

Permit Conditions Relating to Trees

When a permit is approved and the tree report has informed the assessment, the conditions attached to the permit will usually include specific arboricultural requirements. These are enforceable legal obligations tied to the approval, not suggestions.

Common tree-related permit conditions in Melbourne include requirements for tree protection fencing to be installed before any works commence, restrictions on soil disturbance within the tree protection zone, obligations to engage an arborist to supervise specific stages of construction, and requirements for a post-construction arboricultural inspection.

Understanding what conditions are likely before submission allows consultants to structure reports so the resulting conditions are workable for the project team. A condition that requires supervision of every excavation task within fifty metres of a significant tree can create significant programme disruption if it was not anticipated at the design stage.

Review your permit conditions carefully when they arrive. If conditions reference the submitted arborist report, that report becomes part of the legal framework of your permit and any deviation from its recommendations could place you in breach.

What Happens If the Report Is Rejected or Deemed Insufficient

Council will not always formally reject a tree report. More commonly they will issue an RFI or note deficiencies within a broader refusal notice. If your application is refused and tree-related matters are cited, the report itself may need to be significantly revised before a new application or VCAT appeal can proceed.

At VCAT, submitted arborist reports are assessed as evidence. Reports that lack methodological rigour, that make recommendations beyond the consultant's scope, or that appear to be prepared in support of a preferred outcome rather than as an objective assessment, are vulnerable to being set aside. This is another context where the independence of the consultant and the quality of the underlying tree assessment report has direct consequences for project outcomes.

Getting the Process Right From the Start

The post-submission stage is largely determined by what went into the report before it was lodged. Reports that are structured around council expectations, prepared by qualified consultants, and grounded in documented methodology move through the assessment process faster and generate fewer complications.

If you have a planning application in Melbourne that requires arboricultural documentation, or if you have already received an RFI relating to a submitted report, contact Arborplan to discuss your situation. We prepare technical tree reports and arborologist reports for development applications, council submissions, and planning reviews across Melbourne.
