Authorities have charged four individuals, including the chief officer of an international livestock carrier, in connection with an attempt to smuggle over half a tonne of cocaine. The narcotics, discovered floating off the Western Australian coast, have prompted a significant investigation.

The shocking find occurred on November 6, when vigilant members of the public spotted packages tethered to flotation devices about 30 kilometers offshore. These bundles were subsequently retrieved by authorities near Lancelin, roughly 125 kilometers north of Perth.

The operation resulted in the seizure of 525 kilograms of cocaine, a haul valued at more than $170 million, underscoring the gravity of the situation. Investigators allege that the drugs were offloaded from an international livestock carrier destined for Fremantle Harbour.

The case took a dramatic turn when, just a day after the discovery, a 46-year-old Croatian man, who served as the vessel’s chief officer, was apprehended, marking a crucial development in this international smuggling case.

It is alleged the drugs were dropped off of an international livestock carrier which was on its way to Fremantle Harbour.

A day later, a 46-year-old Croatian man, who was the chief officer of the vessel, was arrested.

A blue drum and ropes similar to those found with the drugs were found in a search of the ship, whilst police also allege a CCTV camera had been blocked whilst the drugs were being offloaded.

Three other men were also charged in relation to the attempted importation, with two men being tracked down by authorities after getting into distress in the open water.

On November 3, emergency services were called to a boat that was taking on water off the coast of Guilderton.

Two men from Sydney, aged 19 and 36, were found and brought safely to shore, whilst further investigations led to the identification of a 52-year-old Perth man.

It is alleged the trio made multiple attempts to retrieve the cocaine from the ocean after launching boats from the Two Rocks Boat ramp.

They were all subsequently arrested, with the two Sydney men being extradited to Western Australia.

The four men have been charged with multiple offences, with the 19-year-old man and the 46-year-old Croatian man facing the most severe penalties of life imprisonment if found guilty.

Police say investigations are ongoing, including into the origins of the cocaine, and they believe more arrests will be made.
