Australian authorities uncover 216 kilograms of drugs on Tuesday.
Hidden in over 3,000 cartons of raisins were around 97 kilos of heroin and 119 kilos of pseudoephedrine, worth an estimated 30 million U.S. dollars.
The drugs are believed to have originated in Afghanistan, and were shipped through Iran.
One customs official said authorities worked hard to piece the relevant information together.

"It's a bit like putting a jigsaw puzzle together. There was no previous intelligence on this particular syndicate, from our perspective, and it was just pulling the threads together."
Australian police have arrested a 34-year-old man in a Sydney suburb in connection with the illicit haul.
