The voltage and AC frequency would be the only real issue I would think. Frigs are a bit more sensitive than most other appliances to that.
There are a couple of Australian lawyers on the Forum and perhaps they will chime in. My US legal background should not be trusted outside of the US. However, when I looked at the Australian law it appears to be designed to "encourage" an importer to have the offending gas taken out before the vehicle/device reaches Australia. Thus any recharge would be made in accordance with Australian laws which may require adapting or changing the equipment.
$3,000 AU buys a lot of refrigeration work.
Having lived with boat refrigeration back into the last century I think it is wise to have a system which fully complies with the local rules. You don't want your food to go bad a couple of years from now while you try and obtain special gases or parts.
