WA Police deputy commissioner Gary Dreibergs said 216kg of crystal methamphetamine had been seized from two properties in suburban Perth — the equivalent of 2 million individual hits on the streets, with a value of around $200 million.

He said 14 people, eight Chinese nationals and six Malay nationals, would be charged over “the biggest methamphetamine seizure in WA this year”.

“It is evident that this seizure is part of a well-funded, highly-organised, sophisticated overseas criminal organisation,” he said.

“Without the outstanding joint work of all Australian law enforcement agencies, this result would not have been achieved.”

More than 150kg was seized from a house in East Cannington, and a further 50kg from a house in Embleton.

The investigation into the alleged drug smuggling operation started when the foreign boat was intercepted earlier this month and escorted to the Geraldton Fishermen’s Wharf, 400 kilometres north of Perth.

The vessel was inspected for several days as firefighters wearing protective gear removed containers suspected to have been used to hold chemicals.

Eight Chinese crew were later taken into immigration detention by the AFP as they “did not have valid visas to enter Australia”.

No drugs were found on the boat, but officers found drugs they say had been shipped in aboard the vessel at the Cannington and Embleton properties.

The operation involved officers from WA Police, the Australian Federal Police (AFP), and Australian Border Force.

The details of the case and those charged had been the subject of strict suppression orders issued by the Perth Magistrates Court in closed hearings over the past few days.
