Independent tree advice for Greater Sydney.

Arbzone is a Sydney-based consultancy business providing independent tree advice and professional arboricultural consulting services throughout the Greater Sydney region.

We work with homeowners, strata managers, developers, architects, builders, councils and government organisations, delivering practical, evidence-based arboricultural advice tailored to each project.

Arbzone was founded by Roy Gommans, a qualified arborist holding the nationally recognised AHC50524 Diploma of Arboriculture (AQF Level 5).

With over 15 years of experience working as an arborist in both Australia and The Netherlands, Roy combines extensive practical knowledge gained as a professional climbing arborist with arboricultural training. This combination of field experience and technical expertise allows Arbzone to provide balanced, practical and independent advice.
