Lots of red tape
Have not read the various rules/regs but this seems to be the "core" part that covers importation
Reg' 12 says that if you can prove that a vehicle manufactured o'seas did meet Oz standards when manufactured then the Minister must allow import.
Reg' 13 is about importing vehicles that have been owned/used o'seas by the applicant
Reg' 15 is probably what Deus use to import limited numbers
Reg' 16 says the must allow you to import a vehicle manufactured before 31/12/89, do not know how that allows you to register but if I recall there is no probs.
and there is a lot more to be gleaned from the regs and some cross referencing, no time -- back to work....
