Can you hire a car under 25?
Yes, with some companies. Avis rents from 21 but limits under-25 drivers to specified vehicle groups. Hertz also rents from 21 and applies a young-driver surcharge if the renter or an additional driver is 24 or under. The vehicle and payable rate can change once the actual renter age is entered.
For a long booking, check how the surcharge is counted rather than multiplying a daily figure across the whole rental: Hertz caps its young-driver charge at seven days in each 30-day rental period. The amount for your booking is quoted at reservation.
Can you hire at 18, 19 or 20?
Avis and Hertz both start at 21 in Australia, and Hertz allows exceptions only if approved beforehand in writing. Other companies set their own age rules. Search with the real driver age and read the selected company's age, licence and vehicle-group terms before paying.
Does the licence type matter?
Yes. Avis requires a current and valid licence that is not a restricted, learner or provisional licence, held for at least 12 consecutive months. Hertz accepts a provisional licence if the driver meets its other conditions, including holding a licence (provisional or full) for at least 12 consecutive months, but does not accept a learner's permit. Check the rules of the company you book with for every driver.
What about an additional driver?
Only people named on the Avis rental agreement may drive, and any additional driver must be present at the time of rental with a current, full and valid licence. Hertz charges an additional driver fee, and a driver who does not meet its usual requirements must be added as an additional driver and show their licence. Check the age and vehicle rules for each driver before collecting the car.
