For information only I did a Google for SA and found only one site that offers anything above the SA compulsory but expensive RideSafe learner program

Marylou NEES at Garage Motorcycles, Strathalbyn SA, offers post license motorcycle rider training via her company "Roadcraft". She runs two courses.
Phillip Island - 2 days 3 night accommodation Cost $775.00
Refresher Course - one to one tuition only Cost $200.00
I got my license in the old days when there was no training required, so I did the Refresher Course a number of years ago when I started riding again. It was well worth the dollars spent, and concentrated on road riding skills, and not slow speed circus tricks. Observation, use of gears, braking and engine braking, throttle control, road riding corner lines and much more were covered, and 90% of it was "on the road" tuition.
