One of Australia’s largest drug busts took place aboard Kypros Bravery, a Cyprus-registered cargo carrier, UK media reported on Saturday.

The Australian Federal Police seized 416 kilos of cocaine worth over $166 million, arresting four Filipino crew members who allegedly threw the drugs overboard in ‘deep waters’ off the Yorke Peninsula on March 15.

The AFP said the joint investigation found the cocaine off the peninsula on March 21 and that the enormous shipment was destined for all Australian major cities.

“While the alleged cocaine importation is the largest ever detected by law enforcement in South Australia, it is most certain the drugs would have been trafficked to other Australian states,” AFP Assistant Commissioner Peter Harvey told the Daily Mail.

The sailors, aged between 29 and 44, face charges of importing a border-controlled drug with a maximum penalty of life imprisonment.
