FYI the requirements differ by state/territory.

In Tasmania you do a free short course and theory test (can be done online) to get your learner license (small fee, <AU$50) and L plates.

L-platers then need 80 hours of logbook driving including 15 at night. A driving school isn't required but some participating schools can get you double hours (1 hour lesson = 2 hours in logbook, up to 10 hours).

After this you do your P1 test and a hazard perception test and go from your L plates to P1 plates on passing.

You hold the P1 for 12 months then it's upgraded to P2.

Under 23s have to hold the P2 for two years before it's upgraded to the full license. If you're 23-25 you hold it for 12 months or until you're 25. Older than 25 = 12 months.

The path was changed in 2020 from L1 -> L2 -> P1 -> P2 -> full by merging L1 and L2 to L and changing logbook requirements (I think from 100 hours).

L-platers can't go more than 90kmh anywhere, P1 more than 100kmh, P2s can go as fast as allowed.

Of course you have to display the appropriate plates showing your level on the front and back of the car. Here it's not required for the plates to be on the outside of the car (heard that differs in other states).

If you go the whole way without any offences you get a free 3-year full license.
