getting a cams license is easy, depending on what you want to do.
I recently applied for a L2S License [meaning Level 2 Speed] which allows you to partake in most events like hill climb, super sprint, motorkana, etc. The L2S License costs $85 and you can may by money order, cheque or credit card.
you have to be part of a CAMS affiliated Club in order to get a cams license also. The SAU NSW Members club is the club to join for all you SAU people.
You also need to meet certain scruitneering criteria, like having a fire extinguisher in the car etc. [ i wont go into much detail]
you will also need a number and triangle for your car you can get magnetic ones, much like i purchased from the NSCC.
its a pain in the ass setting everything up and getting everything organised, but it is the best fun when your out there racing!
hope this little info helps you a bit
