I need help with my commerce homework concerning law. I needed to outline some possible options of resolving the following crime issue- recent shooting in Bondi in Sydney's east on 15th April 2011. (e.g. kinds of courts, etc.)

I was wondering if reporting the crime to the poilce is good and charging the suspect and bring him to the DISRICT COURT and if the shooter is not satisfied with his sentence, he can appeal in the CRIMINAL COURT OF APPEAL?
What are other possible ways of solving the issue?
