Arborist Report Cost

There is no official rate card for consulting arborist reports. City of Sydney's current guidance specifically states that consultant arborists do not have standardised professional rates and that the cost of a tree report depends on the report type, scope and number of trees assessed.

Current published pricing nevertheless gives some indication of the range consumers may encounter.

As checked in August 2026:

• Sydney Arborist Solutions publishes a range of approximately $350–$1,100+ for council tree reports.
• The same provider publishes approximately $800–$2,500+ for tree impact assessments / Arboricultural Impact Assessments associated with development.
• Hipages' 2026 Australian cost guide places arborist reports broadly in the $450–$2,000 range, with more comprehensive impact assessments toward the upper end.

These are published examples, not Development Reports price estimates and not an industry-wide average. Actual fees can fall below or above these ranges depending on the required scope.

The report type and amount of arboricultural work required can make a significant difference to the fee.

Type of report

"Arborist report" is a broad term. A consultant may be asked to prepare:

• A tree condition or health report.
• A report supporting a tree-pruning or removal application.
• An Arboricultural Impact Assessment for a development application.
• A Tree Protection Plan.
• A tree risk assessment.
• Root investigation or root mapping.
• A tree management plan.
• Specialist diagnostic or structural testing.
• Construction-stage monitoring or certification.

These services can involve very different amounts of site investigation, analysis and reporting. Do not assume that a quote for a basic tree report includes an Arboricultural Impact Assessment.

Number of trees

The number of trees requiring assessment is one of the clearest cost drivers. A single-tree inspection may be relatively contained, while a development involving numerous trees can require substantially more: measurement, identification, photography, condition assessment, retention-value assessment, protection-zone calculations, impact analysis and reporting. Neighbouring and street trees may also need to be assessed where the proposed development could affect them.

Development complexity

For a development application, the arborist may need to review much more than the trees themselves. Relevant information can include architectural drawings, survey plans, proposed excavation, driveways, retaining walls, stormwater works, services, landscape plans, changes in ground level and construction access. The more interaction there is between the proposed works and retained trees, the more detailed the assessment may need to be.

Tree Protection Zones and Structural Root Zones

Development-related assessments may require calculation and analysis of Tree Protection Zones (TPZs) and Structural Root Zones (SRZs). Where proposed works encroach into these areas, the arborist may need to assess the significance of the encroachment and recommend design or construction measures. This can increase the amount of analysis required compared with a straightforward tree-condition report.

Root investigation or mapping

Sometimes the location or condition of tree roots cannot be adequately understood from plans and visual assessment alone. Additional work may involve root mapping, non-destructive excavation or other investigation. City of Sydney's current arborist guidance notes that root mapping and reporting are additional works unless they were included in the original scope.

Specialist testing

Some trees require investigation beyond a visual ground-level assessment. Depending on the issue, this can include aerial inspection, decay or resistance testing, sonic tomography, pathology assessment and detailed root investigation. City of Sydney notes that further analysis such as aerial inspection, resistance testing, pathology assessment or root investigation can be required in some circumstances. Specialist testing can add to the cost of the assessment.

Qualification requirements

The professional qualification required can depend on the council and report purpose. For example, City of Sydney currently accepts relevant tree reports from consultant arborists holding a qualification equivalent to Australian Qualifications Framework Level 5.

Do not present AQF Level 5 as a universal requirement for every NSW council or every type of tree assessment. Before accepting a quote, check what qualification the authority requesting the report actually requires.

Revised plans and changes to the project

Development designs change. If an architect moves a building footprint, driveway, basement, retaining wall or service route after the Arboricultural Impact Assessment has been prepared, the arborist may need to reassess the impact on trees. City of Sydney's guidance notes that changes in scope or assessment of revised or new plans for an Arboricultural Impact Assessment are likely to create additional costs.

Construction-stage involvement

Some projects require arboricultural involvement after development approval. This can include reviewing construction methodology, inspecting tree-protection measures, supervising work within protection zones, attending site during sensitive excavation, monitoring retained trees, and providing certification or completion documentation. Ask whether these services are included in the original fee or priced separately.

Site location and access

Travel, difficult site access and the time required to inspect trees can also influence the quote. If specialised equipment or multiple site visits are required, ask whether these are included.

Urgency

If the report is required quickly because of a council deadline or imminent project milestone, expedited work may cost more. Do not assume every consultant applies an urgency fee. Ask whether it applies to the quote.

Before comparing quotes, make sure the consultants are pricing the same service. A useful written quote should make clear:

• The type of report being prepared.
• The purpose of the report.
• Which trees are included.
• Whether neighbouring or street trees are included.
• The consultant's qualification where this is relevant to council requirements.
• Which drawings and documents will be reviewed.
• Whether Tree Protection Zone and Structural Root Zone assessment is included.
• Whether a Tree Protection Plan is included.
• Whether root investigation is included or would be an additional service.
• Whether specialist testing is included.
• Whether revised plans can be reviewed.
• How many report revisions are included.
• Expected turnaround time.
• Whether council requests for clarification are included.
• Whether site meetings are included.
• Whether construction-stage inspections or project-arborist services are included.
• What would trigger additional fees.

If the report is required by a council or development consent, send the consultant the actual requirement when asking for a quote.

This is worth clarifying before accepting a quote. City of Sydney's current arborist guidance says that where the City asks for further information after an application has been lodged, the consultant arborist should not charge simply to complete information that should have formed part of the original application, and should account for this when quoting.

However, the same guidance distinguishes this from changes in scope or revised plans, which are likely to involve additional fees.

This is City of Sydney guidance and should not be presented as a universal contractual rule applying to every arborist engagement or council.

The practical takeaway is to ask the consultant in writing:

• What responses to council queries are included?
• How many revisions are included?
• What counts as a change of scope?
• What happens if the architectural plans change?

Consider two hypothetical projects.

Project A: straightforward tree report

A property owner needs an assessment of one tree for a council application. The work may involve one tree, a site inspection, basic measurements and photographs, condition assessment and one written report. This is a relatively contained scope.

Project B: Arboricultural Impact Assessment for a development

A new development involves:

• 18 trees on the site;
• neighbouring trees near the boundary;
• two street trees;
• excavation for a basement;
• proposed works within several Tree Protection Zones;
• architectural and landscape drawings;
• assessment of trees for retention or removal;
• a Tree Protection Plan; and
• later review of revised plans.

Although both services could loosely be described as an "arborist report", the amount of professional work involved is completely different. This is why headline prices should always be compared against the actual scope.

These scenarios are illustrative only. Do not attach invented dollar values to them.

Providing the right information can help the consultant understand the scope before pricing the work. For a development-related report, this may include:

• Property address.
• Council area.
• Council request or DA documentation requirement.
• Current survey.
• Architectural plans.
• Landscape plans.
• Civil or stormwater plans where relevant.
• Details of excavation or basement works.
• Information about trees on neighbouring land or the street.
• The project timeline.
• Any previous arborist reports.
• Any council correspondence relating to the trees.

If a council has requested a specific report type or qualification, send the exact wording. Do not simply ask for "an arborist report" if you already know the council requires an Arboricultural Impact Assessment, Tree Protection Plan or another specific document.

For development-related arboricultural work, comparing two or more written quotes can be useful. But compare the scope rather than just the bottom-line fee.

One consultant might include:

• all affected trees;
• neighbouring and street trees;
• a Tree Protection Plan;
• revised-plan review; and
• responses to council queries.

Another quote may cover only the initial assessment and report. The lower fee is not necessarily cheaper once additional work is required.

How much does an arborist report cost in Sydney?

There is no fixed Sydney rate. Current published pricing checked in August 2026 shows straightforward council tree reports beginning at several hundred dollars, while development-related Arboricultural Impact Assessments can commonly reach well above $1,000 depending on the number of trees and complexity. For example, Sydney Arborist Solutions currently publishes approximately $350–$1,100+ for council tree reports and $800–$2,500+ for development tree-impact assessments. These are examples only, not an industry-wide rate.

How much does an Arboricultural Impact Assessment cost?

A development-related Arboricultural Impact Assessment generally costs more than a simple single-tree assessment because it can require review of project drawings, assessment of multiple trees, calculation of protection zones and analysis of proposed development impacts. Current Sydney published pricing examples checked in August 2026 include approximately $800–$2,500+ for this type of assessment. Complex sites can cost more.

Does an arborist charge per tree?

Providers structure their fees differently. The number of trees is an important cost factor, but a development assessment also involves project review, site conditions and reporting. A consultant may therefore quote a project fee rather than simply multiplying a fixed price per tree.

Does the cost include a Tree Protection Plan?

Not necessarily. A Tree Protection Plan may be included within an Arboricultural Impact Assessment, offered as an additional document or required later as the project progresses. Ask what is included in the quoted scope.

Does the fee include root mapping?

Do not assume it does. City of Sydney's arborist guidance specifically notes that root mapping and reporting are considered additional works unless included in the original scope.

Will I pay more if my plans change?

Possibly. If changes to the building, excavation, driveway, services or other works alter the potential impact on trees, the arborist may need to reassess the development. City of Sydney's guidance notes that reviewing revised or new plans for Arboricultural Impact Assessment reports is likely to involve additional costs.

Do I need an AQF Level 5 arborist?

It depends on what the relevant council or authority requires. City of Sydney currently requires relevant consultant arborist reports to be prepared by a consultant arborist with a qualification equivalent to AQF Level 5. Other councils and report types may have different requirements. Check the specific requirement before commissioning the report.

Is the cheapest arborist report likely to be accepted by council?

Price alone does not determine whether a report is suitable. What matters is whether the consultant meets any required qualification, the correct report type has been prepared, all relevant trees and development impacts are assessed, and the report addresses the council's requirements. A low-priced report with the wrong scope may ultimately require additional work.
