The Apaches are a biker gang in Australia
Membership: hundreds (minimum)
It's a national-level gang, one of the Big 5 biker gangs on the island continent. The gang is an old-school "traditional" biker club. Like the other biker gangs it's involved in dealing weapons, drugs, and water.
While there is no "Apaches", there is a biker gang called "Comanches" which was born in Australia and is one of it's two most powerful biker gangs at this time. The Apaches may be analogs of the Comanches.
