Driving whilst disqualified is a fairly serious offence and is certainly capable of resulting in a custodial sentence if repeated.
The offence of falsifying information appears much less serious:
but you should count yourself lucky the officer did not accuse you of a more serious offence:
Each penalty unit referred to in the above section is $110, so noting the driving whilst disqualified (for a second offence) can incur a penalty of 50 penalty units or $5,500 plus up to 2 years imprisonment.
Because it is only a year since your last offence the court may be unwilling to impose a lenient sentence unless there is some extenuating circumstances that would at least partially excuse your driving without a license and depending on the sentence and circumstances of your previous offence, and your overall driving history, a prison term is not out of the question.
I would strongly advise you to engage a lawyer to represent you at the hearing and ensure your case is as well prepared to cast your offence in the best possible light. Even if you are going to plead guilty, the involvment of a lawyer will at least signal to the court that you take the legal proceedings seriously and no doubt your lawyer will find something in your circumstances to raise with the court as a reason for leniency. If you just turn up on your own without a properly prepared case, the court may well just form the view you do not take the court seriously and then impose a penalty to make sure you do in future, which may be quite harsh.
If you need help locating a lawyer contact the Law Society of NSW as they can refer you to suitable lawyers in your area.
