Driver's license
The minimum driving age varies between 16 and 18 years of age in different States and Territories. After the minimum age, a graduated licensing scheme operates, with state variations.
Minibus
In the UK the following information regarding Minibus driving licences is important:
"The holder of an ordinary car driving licence which was obtained prior to January 1997, once aged 21 years minimum, may drive a Minibus with a capacity of 16 passengers. Where the "ordinary car driving licence" is obtained after December 1996, they will have to take a separate test to drive a vehicle with a capacity of more than 8 passengers. However, there is an exemption for certain volunteer drivers, where the vehicle does not exceed 3500 kg GVW (or 4250 kg GVW if the vehicle is designed to be wheelchair accessible).
