Just checked Court Data Australia for all the aliases. I didn't pay so don't have access to all the details, but here's what came up:
RB x2 criminal (interesting!)
MCdH x1 criminal (interesting!)
DdH x1 civil (could relate to Coles unpaid staff wages, was a huge case at that time, but did she work?)
I paid to have a snoop, but it was worthless really.
So, RB's has the listing type as "Mention (SDRO)" as does MdH. After Googling "SDRO" (State Debt Recovery Office), it seems to be traffic infringements. He learned nothing from his early days, did he

RB's second listing was a hearing, so he may, or may not have been fined or something.
DdH is V Coles; no elaboration
In civil cases, anyone can take someone else to court in order to solve a dispute.
But MCdH must've been apprehended and charged by police for allegedly doing something illegal.
