@afghan bob mentioned. First offence, and those 3 charges. You could get away with a $750-1k Fine, with no conviction, if you're utilising the Courts
Duty Solicitor* . That's if you were prepared to serve yourself up and get it finalised on the day.
But if you wanted to burn some dollars on proper representation, drag it out in an attempt to minimise the outcome. Then there's always that option that comes at an unknown expense.
*If you're intending to go the Duty Solicitor route. Get there a bit ahead of time before the Court session starts, and ask someone/Admin Staff who the nominated Duty Solicitor of the day is, and chase them down from there. They should do a quick summary of your case with the information you provide them (take in your charge sheet with you, if in case they don't have your charges readily available to them). Before Court starts for the day. Then once it's underway, wait until your name is called out 'n front up when it's time.
Also, it doesn't hurt tidy yourself up a bit, so you come across somewhat respectable. And surprisingly enough, some Judge's appreciate it if you bring a close family member along to sit in the gallery to show that you do in some way have support of a family/friendly network of folks. I don't fully grasp that one either. But it is what it is.
Fuckin' sucks to hear how you went down just before Christmas,
@StewPot All said 'n done though. You should come out alright for First Offence in most of QLD. Especially around SEQ. In some of the Regional Redneck Country Courts, it probably wouldn't hurt to get some paid legal representation to cover your arse, just in case..
