Two men accused of helping import almost three tonnes of illegal drugs into Australia have been extradited from Dubai to Sydney.
Police say it marks the end of an eight-year investigation into an international crime syndicate accused of supplying MDMA and ice in NSW.
In December 2013, detectives from the organised crime squad established Strike Force Millstream to investigate the large-scale supply of prohibited drugs in NSW.
Police say 28 people have since been arrested and charged for their roles in the syndicate, while a further two men were apprehended in Dubai, United Arab Emirates, in June last year.
Since that time, the NSW Police has been working with international law enforcement and Commonwealth agencies to seek the extradition of the men.
Those two men, aged 36 and 38, landed in Sydney about 10.30pm on Wednesday and were later charged over their alleged involvement in importing three tonnes of drugs with an estimated street value of $150 million.
The men were refused bail to appear at Central Local Court on Thursday.
Police are expected to provide further information about the arrests at 10am.
