International Driving Permits (IDP's) are recommended when you intend driving overseas.
In Australia, the Government appointed the Australian Automobile Association (AAA) as the only authority to issue permits. As a member of the AAA, the RACV issues IDP's through RACV shops.
An IDP is a widely recognised documentand is useful for photo identification purposes. You may also need one to rent a car overseas.
