Certified Locators are certified by industry experts to distinguish them from “DIY” or self-authorised locators. To gain certification locators must pass a comprehensive theory assessment and practical field assessment conducted by an industry assessor. Certified Locators will need to present appropriate equipment and demonstrate expertise to safely and competently use different locating techniques to accepted industry standards.


Gives your company’s certified locators access permissions to utility networks for the purposes cable and plant location. For now, only the Telstra infrastructure is included in this agreement. We are currently negotiating with several providers to include as many utilities into the process as possible – making the CLO program a one-stop shop.


This four hour training course covers the requirements and regulatory obligations of locating and identifying subsurface utilities for Site Managers, HSE Managers Supervisors and Leading Hands on construction sites where excavation work is proposed to be carried out.

The course will inform participants of their legislative obligations and will show how to apply Australian Standard 5488 to reduce the possibility of damage and additional cost.

What our customers say

The new DBYD Locator Certification is going to challenge service locators across the industry. The theory component of the exam covers a wide range of locating techniques that would be carried out by experienced locators. Broken into three components the locator is tested on knowledge of Telstra infrastructure to satisfy APL requirements, DBYD knowledge and locating principles. I found the theory component had enough scope to adapt or change to suit the introduction of other asset owners or to test new skills. The pass percentage score and number of attempts is sufficient enough to assess a locators true knowledge. The practical component gives the locator the opportunity to demonstrate their knowledge in a real world scenario. The standards set for this were quite high. The locator had to be knowledgeable in their field and to demonstrate principles across a number of different assets. Overall I can see from the range of questions, the high standards, qualified trainers and assessors, that DBYD will achieve its goal of having highly trained and skilled locators in the industry.

I completed the Utility Advanced Line Locating online course to challenge myself after being a locator for over 20 years. I found the course material excellent, well prepared and I have taken aspects away that will change how I conduct my work. I would definitely recommend this course.
