I can't give exact process for Adelaide. I done mine in Perth. I'm sure it's similar.
Get restricted licence from from electrical board ( mine was energy safety)
Enrol at college to start change over course
Get employed
2 weeks college with practical exam and paper exam
Complete 12 assignments at home
Complete log book (roughly 6-8 months work experience, quicker if more hours worked)
Tele/coms course 4 days with practical exam and paper exam
Capstone course 4 days ( pretty much AM2 )
once all all the above is completed you can get an A class licence. I'd say with the time off work this cost me roughly $15,000
Also getting employed can be pretty hard. Some people get paid as little as $20 ph doing domestic work. If you have good experience and background it will be easier to get a better paid job $35 plus
