dont sweat it.
you have you first date givven to you, thats just to show up and plead not guilty.
6/12 weeks later you will get a court date given to you.
if the date is gonna be over 12 months then hire someone.
if it in the first year just go by yourself, show p early and talk to te JP.
in court they will most likely just drop it to a 49 over. if they do you can take the 49 over as it is just a regular speeding ticket, no different then 10km over. if they say no to that, then they will ask about your lawyer and if you have one. you say you dont have one and need time to retain one (probably give u 30 days or so). then you get a lawyer and he deals with it.
that way your only looking at the $600 speeding ticket and insurance is cool. a lawyer to fight a 172a is gonna be a lot more then $800 so you can save some money at first if it goes your way.
they will give you the time to get a lawyer because if they dont let you get one and come back then you can appeal the ruling because you did not have proper representation
