According to Avis Australia's renter requirements, I am seeing:

"We may refuse to allow any driver to drive the vehicle who: (i) does not hold a valid and current driving licence in the country of rental for the entire rental period, (ii) has not brought an international driving licence or official translation (if applicable), (iii) has not held their licence for the minimum period required by the rental location, (iv) has driving related convictions, or (v) who does not meet our identity, security, driving licence or credit checks."

Since they are an English speaking country and no translation is needed for USA licenses, any one has any success story on renting cars from Avis in Sydney without getting an International driving license from AAA?

thanks!
