Its in the council depot next door to the sturt police complex. Just drive in and join the queue/fill out forms. cost $25 payable at marion rego after inspection. They will just check engine no, compliance plate and rego plates. 17's should be ok, but they may pull you up for any blatantly obvious defects tho. generally its pretty cruisy, but they only open a couple of days per week usually 10-3ish.
^^ok what they said!!
