NSW What is the Maximum Penalty for Incitement Under Common Law?

[dennisr35]

a) What is the maximum penalty for incitement at common law in NSW?

b) Is incitement to incitement punishable at common law in NSW?

Please note that I wanted to know the penalty if the incitement did not succeed (crime incited wasn't committed).
