Australian authorities uncovered a $123 million crypto laundering syndicate using legitimate businesses as cover. An 18-month probe exposed a cash-in-transit security firm, a classic car dealership, and a sales promotion company funneling illicit funds. Criminals used dead-drop cash pickups, armored vans, and bank account layering to disguise proceeds before converting them into cryptocurrency. Raids across Brisbane and the Gold Coast seized cash, crypto, documents, and $21 million in assets. Four suspects, including company directors, face charges carrying up to life imprisonment. The case highlights how criminals exploit legitimate sectors while reinforcing the importance of multi-agency collaboration and blockchain tracing.
