Three men, including the brother of slain gangland kingpin Wally Ahmad, have been refused bail on drug-smuggling charges.
They were arrested on Tuesday along with seven other people when police carried out dawn raids in Sydney after investigating two inter-related organised crime syndicates.
Five people were also arrested in Dubai and two others in The Hague, reportedly including the brothers of Kings Cross club identity John Ibrahim.
Ahmad "Rock" Ahmad, 39, covered his face with his hands and a hooded jumper when he appeared via audiovisual link at Central Local Court on Tuesday.
Co-accused Jehad Jodeh, 29, also appeared via AVL charged with importing 800kg of methamphetamine in Sydney between November 10, 2016 and August 8, 2017.
Ahmad is accused of conspiring to import a commercial quantity of the same drug between the same dates.
They were both formally refused bail by magistrate Clare Farnan and are due to face court again on November 1.
A third man, 42-year-old Ali Jomaa, is facing six charges as part of a different police operation.
According to court documents Jomaa has been charged with bribing an Australian Border Force officer on July 18.
He also allegedly dealt in almost $2.5 million in proceeds of crime, directed activities of a criminal organisation, imported a commercial quantity of methamphetamine and imported tobacco products with the intention to defraud revenue.
Jomaa, who represented himself, was formally refused bail by Ms Farnan and is due to return to court in October.
A number of other accused are expected to face the same court on Wednesday.
