Two men are behind bars, accused of a botched attempt to retrieve more than half a tonne of cocaine from the ocean that had been dropped overboard from a bulk cargo carrier.
Australian Federal Police say the audacious plan came undone when a 45-year-old man got into trouble and needed rescuing from his seven-metre fishing boat on August 7, off the Western Australia coast at Denham.
Two Queensland men have now been extradited to WA, charged over their alleged involvement in the bust worth more than $200 million, which the AFP says was organised by a transnational drug trafficking criminal syndicate.
The second man, a 53-year-old who also travelled to WA, was waiting at a boat ramp for the drugs to be retrieved by his partner, with a plan to drive the drugs back to Queensland, police said.
Four days later federal and WA police officers raided a Kalbarri property, 570km northwest of Perth, where they found about 560kg of cocaine wrapped in plastic.
