As with all trades & professionals, there are different levels of qualification for operators and consultants. If you are employing a consultant, they must be qualified to AQF (Australian Qualification Framework) Level 5 Diploma in Horticulture (Arboriculture). If you want a tree removed or pruned professionally, your arborist must be qualified to minimum AQF Level 3 in Arboriculture or AQF Level 3 in Horticulture (Arboriculture). When engaging an Arborist (as any level), do not be afraid to ask to see proof of Qualifications, insurances and references. Always get more than one quotation and compare advise as well as price.
