The writers of a Landrover handbook in the UK would have no idea what constitutes a gazetted road in Australia.
No, the writers had something in mind - most likely something like a gravel road is onroad and a firetrail in the mountains and worse, is offroad. Unfortunately LR does not provide a definition in the handbook and if someone got booked towing over 1000kg with a braked trailer offroad then it would be up to the courts to determine what LR means by offorad.
Eg Seaside beach on Fraser Is is a gazetted road and for the most part could (arguably) be classed as onroad but some sections (still gazetted) are definitely offroad such as the bypasses around the headlands and the rocks at the northern end of Orchid Beach.
We clearly all have thoughts but until someone from LR tells us what they mean then we can only air our views.
