It's ironic how 60 Minutes Australia criticizes Dubai for being a haven for money launderers, when the money originates from Australia itself. In the UAE, and in many countries in that area, it's the sender country's responsibility, in this case, Australia, to provide proof.
The money isn't from places like Seychelles or Belize, which might raise suspicions.
Recently, UAE authorities have become very strict on criminals; a tip to Dubai's Al Ameen service can prompt swift action. It seems these biased clown-ish journalism overlooks these efforts.
