Hi Mary08,
It is I james50071 (New Account).
There is no issue if you do not have a personal lawyer. As stated before, I strongly recommend you contact Legal Aid and check if you are eligible. I suggest you begin by contacting LawAccess at 1300 888 529 and they will provide assistance over the phone. The Local Court can give a maximum sentence of two years imprisonment per offence, and five years imprisonment all together; typically they issue fines. Depending on the location of your hearing (Local or District court, as I believe Parramatta has both.), the verdict differs. Of course you could represent yourself, although as stated above, lawyers have significantly higher knowledge of the Law and could benefit you greatly. In Court, legal terminology is commonly used and you may fail to understand, in this scenario - you must express your confusion to the Magistrate, or Judge.
I urge you to contact LawAccess at 1300 888 529 to gain a greater understanding of your case.
