@shakey55 - thanks for the link. I looked on their site and could not find it. Obviously did not look hard enough! I have printed off a copy and will keep it in the Patrol. Problem is - other ADRs specify maximum width of vehicles and such, and depending how you (plod in reality) interpret a particular ADR you may still not be compliant. It all seems silly until you are pulled up in the middle of no where and given a defect notice.
