In Queensland, keep each testable backflow device's identity, site, test results and tester details ready for Form 9. The premises owner must arrange maintenance and testing by a backflow prevention licensee at least annually after registration, and the licensee must notify both the local government and owner within 10 business days of the work covered by section 103. Keep the completed form and evidence of both deliveries with the job.[1][2]
Who registers, tests and notifies
Section 101 requires local governments to register testable devices and monitor maintenance and testing. Section 102 makes the premises owner responsible for registration, with exceptions where it has already been registered or the relevant licensee has given the required notice. After registration, the owner must arrange a backflow prevention licensee to maintain and test the device at least once each year.
Section 103 covers installing or removing a testable device and maintaining and testing it. Within 10 business days after that relevant work, the licensee must give the approved notice to both the local government and the owner. Form 9 is the approved registration and testing form; keep both recipients in your close-out checklist.
What Form 9 asks for
Form 9 (Version 3, 2024) says completion of all applicable sections is mandatory. Use this as a guide to what your own records should hold before the form is completed.

Common questions
- What are the backflow prevention requirements in Queensland?
- For a testable device, check registration with the local government, the owner's annual maintenance and testing arrangement, and Form 9 notification. Sections 102 and 103 set the owner and licensee duties, including notice to both the owner and local government within 10 business days of relevant work.[1][2]
- How often does a backflow need to be tested?
- Under section 102(4), the premises owner must arrange for a backflow prevention licensee to maintain and test the device at least once each year after it is registered. Confirm the device's registration and next due date with the owner and local government.[1][2]
