If you don't have a driver's license issued in Australia, then you might need to acquire an International Driving Permit (IDP) in your place of residence to be allowed to rent a car. It's also important to note that if an IDP is required, it has no validity on its own. You'll have to show your current driver's license your passport and other forms of documentation as well. Lastly, it's important that the credit card you used to book the rental matches the name on your license and passport. Some additional requirements to rent a car internationally are:
- Age restrictions: You must be at least 25 in most countries to rent a car. If you're younger than that, it might still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to what kinds of cars you can rent.
- Driving limitations: Be sure to read the rules and regulations before you drive off the lot. Typically, you can't cross country borders, drive on ferries or on off-road areas with a rental vehicle.
