While sitting at a set of traffic lights a couple of weeks ago I had a policeman do a U turn (illegal U turn mind you

He issues me with a defect notice, and off I went.. I got home and re read the Notice and become confused... Pics Below..


So on part of the notice that I cropped, it says "Inspection Type: Certificate", and it says I need to Produce the Vehicle for a full Certificate of Inspection.. And then a comment that it requires testing to establish DB..
Question:
Am I taking the car to someone to get a RWC, and then to Queensland Transport to get the exhaust tested? Or is the QLD inspection station going to do a full inspection on the car, AND test the exhaust?
Or are they Simply just going to test the exhaust for noise, and off I go?
I am after responses from people who know the PROCESS OF CLEARING A DEFECT in QUEENSLAND, not people in other states, or who's mates dogs cousin knew a guy who did this...
