Pleaded guilty: Adam Freeman, left, leaves court.
Kings Cross nightclub owner Adam Freeman has admitted his role in a multimillion-dollar drug manufacturing operation.
The son of the late underworld figure George Freeman now faces a maximum sentence of life in jail after pleading guilty to the manufacture of a commercial quantity - 19.2 kilograms - of the drug ecstasy, worth an estimated $3 million.
Freeman, 30, who owns a furniture supply business and is associated with a number of clubs in Kings Cross, was extradited back to Australia to face the charges.
He flew to Bangkok on December 16, 2010 - a day after police arrested two co-accused near Tamworth.
Police had stopped a van in which the two men were travelling for a random breath test, and officers allegedly located drugs and equipment to manufacture drugs.
The Crown claimed at the time that the manufacture was carried out at a nearby property.
Analysis of glass flasks in the van contained fingerprints including Freeman's, the documents said.
The men were granted bail initially, and one of them flew to Sydney on December 16 and met with Freeman.
"Following this meeting, Freeman purchased an open ticket to Hong Kong, paying cash," initial court documents said. After that, he flew to Bangkok.
Police from Strike Force Harrower raided the suspected property, which cannot be identified for legal reasons, within weeks, seizing more equipment consistent with the manufacture of drugs.
A toaster and a kettle also bore Freeman's fingerprints.
He was returned to Sydney on August 5, 2011 after he volunteered himself to authorities following the issue of a global arrest warrant.
The crown has previously alleged that Freeman was at the property continuously from November 24 until December 16.
On Wednesday morning, Freeman told the Chief Judge of the District Court, Reg Blanch, he was pleading "guilty" to a single charge that he manufactured a commercial quantity of a prohibited drug at Werris Creek between November 23 and December 16, 2010.
Additional charges relating to a further 40 kilograms were not pursued by the Crown.
His barrister, Ronald Driels, asked for at least six weeks to prepare the case for sentencing.
Justice Blanch adjourned the matter to November 7 for a sentencing hearing.
