Arborist Network is a Sydney tree care company where three generations have been caring for trees.

About Us

We have been providing arboricultural consultancy to a range of householders, companies and statutory bodies for more than four decades. Our clients include national and international clients.

Our team developed the accidental tree fatality database that is used by decision-makers around Australia. You can read the supporting presentation “A review of deaths in Australia from accidental tree failures.”

We believe that owning and managing trees should be enjoyable and affordable. We are conscious of the need not to overservice and to provide affordable advice at a cost that is proportionate to the issue at hand. While we have the capacity to provide a huge range of services and have an immense range of diagnostic tools and equipment from Tree Motion Sensors through to a Scanning Electron Microscope, the use of technology is intended to be an aid that should only be specified where it may provide information that alters an end outcome or where the client seeks secondary confirmation of a known outcome.

Our arborists are qualified at AQF Level 5 or higher. They are all members of the peak industry body Arboriculture Australia and are bound by the rules and the Code of Ethics of the Association. We are committed to keeping current with best industry practices and require all of our arborists to be actively participating in ongoing professional development. It is also likely that your consulting arborist will be active in the education of arborists from Levels 2-5.
