An issue you will have with the import process, is AQIS requirements.
check their web site, you will need to have the car inspected and thoroughly cleaned of all dirt.
it also needs dials to show kph not just mph.
if you are bringing personal effects as well, consider loading all into a 20 foot shipping container, lash and chick the car wheels to prevent movement, and all should be ok.
ive moved a car and personal effects this way.
