Yes. And no. Actually, there's a lot of miscommunication and confiusion around the validity of your driving license aborad. Sometimes the rental company agents may force you to hold an IDP, even while their country laws strictly allow you to drive with an Australian license and even police officers might get confused. That's why we created this website - we collect the Australian laws together with the destination country laws, rental agency rental terms and real life reports from other Australian travelers in every destination.
