your in SYD and therefore the 12month behaviour is reducing you to P plates... iv been through it, after the 12months you have to do the tests again and all that crap... THEY PUT YOU ON YOUR Ps
i went the 3month and still drove SCREW THAT but thats me... you can go on good behaviour for 12months and drive normally or 3months and still normally... as long as you drive normally they USUALLY dont pull you over but it comes down to LUCK
