I think you'll find like anything it is possible.
Are you importing it from OS or has it already landed in AUS?
If importing start here:
Specialist & Enthusiast Vehicle Scheme (SEVS)
Last I checked Backdraft were the only cobra on the (Register of Specialist and Enthusiast Vehicles) SEVS Register.
Ruling No
If it has already landed - Then you'll need to find an engineer and work to comply as per the ADRs (Australian design rules) of the day. Start here:
Australian Design Rules
Further it does matter what state you're from.
BeEst of luck
