No need to carry driver licence

With the assumption that Australia's Road Safety Act is lawful and valid, then from this:

ROAD SAFETY ACT 1986 

- SECT 19

Driver licences

(8)     A person under the age of 26 years who holds a driver licence must have the licence in his or her possession at all times while driving or in charge of a motor vehicle.

Penalty:     5 penalty units.--



________________

Therefore, 
anyone over the age of 26 years old who is stopped by police does not need to produce a 'driver licence'.

Only your name and address (can be business) needs to be stated, and NOT your date of birth.
