Three men have been arrested after they allegedly created false companies to import 180 kg of methamphetamine in a shipment of refrigeration dryers.
The Australian Border Force said officers found the drug while searching for the shipment, which arrived in Sydney from Malaysia in September.
Each of the nine dryers reportedly had 20 vacuum-sealed packages, all of which contained about one kilogram of the white crystalline drug.
In total, the drugs are estimated to have a street value of up to $ 135 million.
Australian federal police were able to trace the shipment to an address in Alexandria, just south of the Sydney CBD.
That month, they raided Chipping Norton, in the southwest of the city, and arrested a 28-year-old man.
During the search, investigators seized a telephone, fraudulent documents allegedly used to plan the import and an estimated $ 250,000 in cash.
Following further investigations, police last month exercised warrants at western Sydney addresses to three other alleged syndicate members.
The men, aged 20, 25 and 30, were each charged with a crime involving the importation of a commercial quantity of illegal drugs.
Police said they also found a large number of fraudulent identity documents, two firearms, ammunition and a ballistic vest during their searches.
They will claim that the trio worked with the man previously arrested for creating fake companies and documents used to import the drug in September.
All three appeared in court in Sydney on November 25 and were remanded in custody to appear again next year, while the 28-year-old who was previously arrested will return to court this week.
AFP Southern Command commander Todd Hunter said border restrictions had not stopped criminals from trying to import illegal drugs.
“Unfortunately, Australians are among the top users of methamphetamines per capita and criminals will replace that demand to make a profit,” said Commander Hunter.
“Now this greed is likely to end in long prison terms.”
