Lil_angel is correct.
There are two diversionary programs that operate throughout Queensland . The first specifically authorises police to use discretionary power in relation to a nominal amount of marijuana and refer individuals to an education program, without officially charging them.
The second option can be for possession of any scheduled drug. However, in this case you will be charged, ordered to appear at court, and then it is up to the magistrate when sentencing to determine whether they feel the diversionary program is a suitable punishment.
Unfortunately, Prison Trip, neither option will be available to yourself as legislation specifies that it can only be used where the individual has been charged with possession (and this is
usually limited to first offenses, at that).
It is extremely inadvisable for anyone to really be discussing whether you will be facing jail time or not. There are so many variables that will be taken into account when your sentence is considered. I would highlight that a supply charge is an indictable offense (i am not sure of whether willful damage is an indictable offense in QLD - i would think not, but you would need to check that). Given that you have been charged with such an offense whilst on a good behaviour bond, the magistrate will be forced to consider sentencing for both crimes at this subsequent trial.
Moreover, do you plan to plead guilty or not? By entering a not guilty plea, you will be forced to go to trial at a District Court and, consequently, the severity of your punishment could be greater than if you were to plead guilty at a commital hearing.
There are obviously a lot of questions that all can be discussed with your solicitor. My personal advice is that if there is any way you can avoid a duty solicitor, do so. Overall, i don't
think jail time is likely given that the amount you were intending to supply was minimal. That being said, it would not be inconceivable for a particularly harsh judge/magistrate to enforce a custodial sentence (although i honestly do not think this likely).
If you have any specific question, you might want to PM me, or, even better, wait to you can get detailed advice from your solicitor.
Peace.
edit: Oops. Greenlighters cannot PM. My bad. I guess you will have to post
