The multiple VIN locations might be year dependent, but I can't remember what year that started. My 73 has the VIN at the A post, the plate on the door post and stamped into the radiator support.

With your VIN missing from these locations I would suspect it had been stolen. Common thing, steal a car from say the US, remove the VINs and ship the car to South America for resale (usually the luxury rides and SUV's). Could be a similar situation with yours, stolen from Europe and shipped to Australia. Did you get a title when you bought it, or was it yours at the time it was stripped of it's VIN's?
