That depends entirely on who comes out to inspect your car. If it's the Indian dude at Burwood, you could be rather screwed. I had compliance documents and a legitimate RWC, yet he knocked the car back because it was too low. I won't say exactly what I did, but I removed something, played dumb and it just passed height the second time. It wouldn't have with people in the car, which he pointed out, but I just played the whole "I'm a girl, I know nothing" card and he eventually let me register it.
