Assurance Trees

Assurance Trees is a specialist arboricultural consultancy based at Oakhampton Heights near Maitland, serving developments and property owners across Newcastle, the Hunter and the wider NSW region. Its focus is singular: getting tree-affected projects approved first time. The practice has stood on every side of the fence a project will face: more than a decade as a hands-on AQF Level 3 tree contractor, then a NSW Builder Licence, and now an AQF Level 5 Consulting Arborist with more than 15 years advising NSW developments. That rare mix means advice that is not just compliant, but buildable and costable.

At the core of the service are the reports councils and certifiers require. Arboricultural Impact Assessments, Preliminary Arboricultural Reports, arborist reports, tree protection plans and pruning specifications support development applications and construction approvals, while the ongoing project arborist and tree works management services keep trees protected through the build itself. A handy TPZ calculator and clear, contractor-friendly documentation make the whole process smoother.

For diagnosing tree health and risk, Assurance Trees brings advanced technical tools to bear. Tree risk assessments (TRAQ-qualified), tree stability assessments, decay testing using an IML Resistograph, air spade root investigations, aerial inspections, and tree surveys with GIS mapping give an evidence-based picture of any tree or treed site. Tree valuation, expert witness work and verbal consultations round out the consultancy offering.

The practice also advises on retaining and improving trees through works such as cabling and support, stem injection treatments, root decompaction and vertical mulching, and habitat creation and nest boxes. Assurance Trees works across government, mining, utilities, schools, residential, and civil and commercial construction sectors, as well as with architects and town planners. The consultancy is independent and conflict-free, carries $20M professional liability and $5M professional indemnity insurance, and treats compliance as the floor, not the ceiling.

Assurance Trees provides consulting arborist services across Maitland, Newcastle, Lake Macquarie, Port Stephens, Cessnock, Singleton, Muswellbrook, the Upper Hunter, Dungog, the Central Coast, the Mid North Coast and Sydney for larger projects. If your project involves trees and needs it approved right the first time, this experienced NSW consultancy is built for the job.
