Well not quite Newcastle. North of Newcastle on the coast there is Nelson Bay/Port Stephens. There are a lot of kids who prowl the streets at night hyped up on ice. They aren't really "gangs" but they always cause shit. Lots of property damage and gang bashings. There's groups that call themselves FPC, Bay Rats/Bay Boys, BBC and other shit like that.
They break into a lot of holiday homes and clean the places out. They're hired by these guys who pay them in ice. They all basically just kid hoodlums but they get mentioned more in the news than any local bikie gang or something.
Anyway, just thought you should know for whatever reason.
