For what it is worth, WA transport wont release original paper work to anyone except the original owner due to privacy laws. One of my old cars that i had sold years ago to a local was since sold to a guy in qld. The only way he could get the car license transfered to that state was for me to obtain original docs from WA transport. Failing me getting them for him the car required re engineering in qld.
Also way back then, engineering was basically three inspections during the build by a transport representative with a sign off against an applicable ADR check sheet. Certainly nothing like what we have now.
It still amazes me in one country with one set of ADRs there is so much variance and no "acceptance" across state borders once a car is licensed. It really should be down to safety checks and rego details being correct.
