Connect with a Certified Locating Organisation (CLO)

Frequently Asked Questions

A Certified Locating Organisation (CLO) is a locating company with properly certified employees who have access permissions to locate certain utilities assets, for example Telstra and Optus.

In addition to being a CERTLOC Certified Locator, locators need to be accredited with Optus to be able to access the Optus network. This is required to meet our legal and WHS requirements.
For all Optus Locator Accreditation enquiries please contact Peter Godschalk at [email protected]

To access the Telstra network for locating purposes, a CERTLOC Certified Locator needs to be registered with a Certified Locating Organisation.
Apart from Telstra and Optus, there are many other utilities that require only CERTLOC Certified Locators access their assets. Please contact us for a full list.

In order to become a CLO, you (the locating company) need to sign a formal agreement with CERTLOC Ltd – who administers the program on behalf of the Utility or Network provider:

  • Demonstrating that your certified locating team is appropriately skilled to identify whatever network type may be present onsite, i.e. they are CERTLOC Certified Locators.
  • That you are using up-to-date and properly calibrated asset location and gas detection equipment.
  • That you have the safety equipment to detect unsafe conditions and are able to deal with them.
  • That your company carries business insurance appropriate to plant location type work for the protection of your clients, the infrastructure and your business.
