It's a tough one, on one hand he "indecently assaulted" a woman (amongst other things). But on the other, all he got was a good behaviour bond. The court system has seen to the case, we don't have all the facts/precedents and they do, it's that simple.
However, recruiting him would be a massive risk for any sporting organisation, particularly one that prides itself on image. So he'd have to come cheap or with some fierce clauses in his contract, maybe both.
I don't think he's a sensible investment for a Super Rugby club, where the PR fall-out is the worst (he made headlines here), the risk considering the consistency of his fuck ups, and the fact that the bad environmental factors are local (the blokes he gets smashed with and Mundine).
Japan on the other hand have corporation teams who are in no way going to sully their reputation for a bloke with his rap sheet. It's not a case of a Toshiba sponsored team hiring an unsavoury character, it's literally Toshiba doing the hiring. Big no-no.
So, I think his best bet is France. Their D2 clubs are showing that they're willing to make big buys and take signing risks. Maybe even a lower ranked Top 14 club could rationalise the risk.
It's a massive watch this space scenario, I like watching his play and personally wouldn't mind it if he rocked up for an Aussie Super Rugby side in 5 years time if he keeps his shit together over that period.
It's rare that someone is beyond redemption, and he certainly isn't, but it'll be years before his name is even relatively clean.
