I am not sure if other builders have seen this before, but the NT MVR supplied me this link with a checklist of all relevant ADR requirements.
He advised these are Australia wide.

He advised the Cobra is classed as a MA vehicle, and that each state and territory can approve exemptions to requirements, example being I am permitted to run live side pipes each side.

He also advised, "information regarding applicable ADRs for your vehicle can be found in the National Code of Practice for Light Vehicle Construction and Modification (VSB 14), a link to which is below";

Also, "Section LO contains a brief description of vehicle categories and ADRs, as well as applicability tables";

So as far as his interpretations go, then all states and territories in Australia are supposed to be following these regs, thought that might give you more info Baz.
