Ok unless changed in the last couple of years the Australian Compliance Plate is always aluminium and is pop rivetted to the car - unless a very good reason it cannot be removed and under normal circumstances cannot be replaced.
On my L320 this is pop rivetted to the B pillar near the bottom - maybe in a different place in an L322.

The LR build sticker has been in the engine bay in all modern Landrovers I have owned. In my L320 it is on the radiator panel just behind the bonnet latch. It is a sticker

For what you are after the build sticker is not necessary but the compliance plate is a must - without that I would say that the car would not normally be registrable as it will have to be checked by authorities.
As I said this information is for the L320 but the compliance plate will be easily sited on the body somewhere around the door frames or in the engine bay - it will be in plain sight.
