if you have a look on the rta nsw site they have all the info on the new rules and what exempt and whats not
also if you had ur p's before the 11july none of these rules affect you unless you lose your license for a "serious" offense.. i havent read up on those offences as i dont plan to get caught
and as far as your 4age in an ae86? thats fine all the normal registration rules apply but nothing new there
basically goto rta site it has everything you want to know
i presume you're in nsw? otherwise disregard most of this and ask someone who knows about ur states rules...
