In a draft amended facts tendered, police said Cody Ronald Ward, 26, of Callala Beach, was the alleged mastermind behind the syndicate which sold a variety of drugs through the dark web on the internet.

He enlisted the help of sisters Shanese Koullias, 24, of Callala Bay and Patricia Koullias, 22, of Quakers Hill who packaged and distributed the drugs.

Police say Ward would import the drugs under a number of pseudonyms, collect the packages from a variety of post offices on the South Coast before having the drugs repackaged and posted at a number of different Australia Post post boxes in the Shoalhaven.

It is reported drugs including cocaine, amphetamine, MDMA and LSD were distributed.

Customers over the web paid using cryptocurrency.
