Recognised engineers and the MVR
NT certification is performed by recognised engineers, whose report is supplied to the Motor Vehicle Registry and recorded against the registration.
The NT is the most portable jurisdiction
The Northern Territory generally recognises interstate certification issued by an engineer approved in their home jurisdiction. That makes it one of the smoother destinations for an already-engineered vehicle — provided you can produce the original certificate and report.
