Police have made a major drug bust, seizing almost $400 million of ice that had been smuggled into the country.

In late 2018, NSW Police, WA Police and the Australian Criminal Intelligence Commission launched Strike Force Ferguson to investigate an international criminal drug trafficking network.

Last month, Australian Border Force officers pinpointed a shipping container at a Sydney facility which was declared to be full of clothing.

Officers took it apart, finding 500 packages of white crystals stashed in six of the 10 pallets.

It turned out to be more than half a tonne of the drug ice, with a street value of $375 million.
