Is Jail Likely? Yep - Your honour, I was on an illegal substance at the time is not a great defence...
Now do yourself a favour read what you wrote above - read it a few times - In particular this bit "the only offences they have committed are assault breach an AVO breach a bond." Now keep reading it until it sinks in.
You assaulted someone, you were given a warning not to assault anyone (the bond). Now the AVO probably means that you were warned not to go near the victim... You ignored that too.... Then you hurt the victim again.
BTW the 'only' offences committed are actually assault, breach bond, breach avo and another assault. Now the breach bond means you were warned and as a result of the breach you will now be charged for the first assault.
Mate, how many more times should you need to be warned before the law has to do something like imprisonment to stop you?
I'd strongly encourage you to pack your toothbrush at the next court appearance because you might not be heading home anytime soon.
