Frequently Asked Questions

What is a consulting arborist, and how are they different from a tree lopper?

A consulting arborist provides professional reports, assessments, and expert advice about trees — often required for council approvals, development applications, or property decisions. Unlike tree loppers, they don’t perform pruning or removals, but instead focus on compliance, safety, and long-term tree management.

Do I need an arborist report for a development application (DA)?

Yes, most councils require an Arboricultural Impact Assessment (AIA) as part of a DA if there are trees on or near the property. Koala Arbor specialises in preparing these reports in line with AS 4970-2009 Protection of Trees on Development Sites.

What qualifications does Koala Arbor have?

Koala Arbor’s principal arborist is AQF Level 5 qualified, with additional certifications in TRAQ, Advanced QTRA, and VALID tree risk assessment. They are also a member of Arboriculture Australia and the Institute of Australian Consulting Arboriculturists (IACA), ensuring advice meets industry best practices.

Can you provide urgent tree risk or hazard assessments?

Yes. Koala Arbor offers tree hazard and risk assessments using internationally recognised methods. This helps identify immediate safety concerns and provides clear recommendations for managing hazardous trees.

Do you help homeowners as well as developers and councils?

Absolutely. Whether you’re buying a property and want a pre-purchase tree report, need advice on tree health, or are concerned about roots near your home, Koala Arbor provides services for both residential and commercial clients.

What are tree root mapping reports, and when are they needed?

Tree root mapping uses non-invasive techniques to locate tree roots underground. These reports are often required by engineers, councils, or property owners to understand the impact of roots on structures, driveways, or new building works.

What are orchid wall systems, and where can they be installed?

Koala Arbor designs and installs vertical orchid wall systems made from recycled materials. These walls create lush green displays for native orchids and ferns, ideal for shaded courtyards, verandas, or indoor spaces with indirect light.
