I doubt Land Rover Australia is innovative enough to have local spare parts purchasing officers. Some suppliers of machinery made overseas do, and sometimes they can and do source some spare parts locally that meet their specifications for genuine parts.
Undoubtedly some genuine spare parts are outrageously priced because the distributer thinks there is no significantly cheaper alternative. On the other hand, costs of parts could sometimes vary considerably depending on manufacturing processes and size of production runs. There may also be a large variation in number and cost of distribution and handling steps, each of which adds to the final price.
The then Spare Parts Manager of Massey Ferguson Australia gave a talk on spare parts at a Grain Harvesting Contractors meeting I attended some years ago. One comment I recall he made was to the effect that "If you come cross a part that you think is outrageously priced, please let us know." Sometimes a purchasing officer investigating it could find it is a part could be restocked from a supplier down the road for a fraction of the cost of one from the other side`of the world through several stages.
Note that if you buy more than one "genuine" part with the same part number, especially at different times and places, they may be effectively the same regarding function but obviously made by a different manufacturer. Conversely, some that do the same job but are different to fit different makes of machine but made in similar general styles are from the same maker.
