Is submitting an EOI the same as registering for a course?
No. An Expression of Interest lets Arb Aus know you are interested in attending a TRAQ course. It does not reserve or confirm a place. However, the information you provide will be used for your registration so you will not need to enter the information twice.
To enrol in a TRAQ course, you must first apply to ISA and receive approval for the ISA TRAQ Program. Once approved, forward your ISA approval email to traq@trees.org.au. If you have submitted an EOI we will send you a link to make payment. If you have not submitted an EOI we will send you a course registration link.
Why does Arb Aus collect EOIs?
The EOI process helps Arb Aus understand demand for TRAQ courses, plan future locations and dates, and support participants to complete the ISA approval process early.
Can I choose a course when submitting my EOI?
Yes. The EOI form allows you to nominate the TRAQ course or courses you are interested in attending. This helps Arb Aus understand likely demand. However, selecting a course in the EOI does not confirm your place.
What happens after I receive ISA approval?
Forward your ISA approval email to traq@trees.org.au. Arb Aus will review the details and will send you the next steps to enrol into a TRAQ course.
I am already TRAQ qualified or previously held TRAQ. What should I do?
Please email traq@trees.org.au with a copy of your current or most recent TRAQ certificate. Arb Aus will review your details and confirm the next steps.
What if my qualification is not listed by ISA?
If your qualification is not listed, you may need to submit an eligibility equivalency request through ISA. The ISA step-by-step guide explains that applicants can select Submit Another Credential and provide supporting information, including the credential name, organisation, website, earned date, proof of credential and proof of content.
Please allow additional time if your application requires this review.

Tree Biology and Mechanics:
Participants will learn how to assess wood structure, decay, tree mechanics, and evaluate their impact on likelihood of tree or tree part failure. Participants will also learn how to identify and assess defects and conditions that may affect likelihood of failure.
Tree Inspection and AssessmentParticipants will learn about types of targets, assess the likelihood of a tree or tree part impacting target, and estimate the consequences of tree or tree part failure. Participants will also learn how to assess site factors that may influence likelihood of failure.
Data Analysis and Risk CategorisationAfter learning the tree and target factors that must be assessed, participants will combine likelihood of failure, likelihood of impact, consequences of failure to derive risk rating. This rating helps the assessor communicate tree risk to clients and risk managers and allows comparison risk levels between trees.
Risk ReportingParticipants will learn skills for clearly communicating tree risk to clients, both in written and verbal reports. Participants will also learn about the key components that should be included in a report after completing a tree risk assessment.
