For the possession charges your maximum is $2,200.00 or 2 years jail or both for each offence.
For the assault is it a maximum of 2 years imprisonment.
Being first offences I suspect you may only get a fin and Good behaviour bond. In relation to the Assault you may also be handed an AVO.
You should have a solicitor assist you and represent you. They will tell you to get personal and business references to assist in mitigation of the penalties.
If you have a good background and character the court may offer a section 10 no conviction but this is all dependent on the background and reasons for the offences and also you showing remorse and good references.
Here is some information about section 10s
I do not believe you will go to jail.
