You can't import a left hand drive vehicle to Australia to drive on the road unless it is more than 25 years old and forms a part of a historical register, be part of a car club permit system etc. If Kia thought it wise they would have imported an AWD version. The roads here aren't covered in snow.
It is yet to be proven that an AWD vehicle has any added usefulness whatsoever. The majority are SUVs that have road use only, only work sometimes in AWD, and are a considerable waste of money here for the majority of buyers.
4WD, selectable. off road use. Yes. AWD. No.
As for the Stinger Conversion. Your best bet would be to import a left hand drive AWD and spend a good proportion of its cost again converting it like the dills at GM do for LHD Corvettes stupid stupid stupid whilst Ford manufacture RHD Mustangs at half the price
