When a tree on your property needs attention, whether it is dying, encroaching on structures, or simply due for maintenance, you will likely hear the advice to “consult an arborist.” But what exactly is an arborist, what qualifications do they hold, and when should you call one?
What Does an Arborist Do?
An arborist is a specialist trained in the science and management of trees and woody plants. Their work goes far beyond simply cutting branches. Arborists assess tree health, diagnose diseases and pest problems, recommend treatment plans, carry out pruning to Australian Standards, and prepare formal arborist reports for council submissions and development applications.

Qualifications and Certifications
In Australia, professional arborists typically hold a minimum Certificate III in Arboriculture (AHC30820). Many hold a Diploma of Arboriculture or higher qualifications. Look for membership in industry bodies such as Arboriculture Australia or the International Society of Arboriculture (ISA). When choosing a tree care professional, always verify their qualifications, insurance, and relevant licences.
When Do You Need an Arborist?
You should consult an arborist when a tree appears unhealthy or unstable, when you need a council permit for removal or significant pruning, when tree roots are causing property damage, before construction near existing trees, or after storm damage. An arborist can also provide a second opinion if you have been told a tree needs removal but are unsure. For more on formal assessments, see our arborist report guide.
Arborist vs Tree Lopper
Not everyone who cuts trees is an arborist. Many unqualified operators advertise tree services without proper training or insurance. The difference matters: an arborist follows established standards, understands tree biology, and carries appropriate insurance. To learn more about the distinctions between different tree care titles, read our article on tree surgeons vs arborists.
How Much Does an Arborist Cost?
Arborist consultation fees in Australia typically range from $150 to $500 depending on the complexity of the assessment and whether a written report is required. This investment is often worthwhile given the cost of tree removal or the penalties for non-compliance with council regulations.
