A man and a woman remain in custody in relation to the discovery of $6 million worth of "ice" in a property in St Clair.
The State Crime Command's Drug Squad and Mount Druitt police formed Strike Force Alcoomie in March to investigate a drug syndicate believed to be involved in the supply of methamphetamines and ecstasy in NSW and Queensland.
Investigators executed a search warrant at a property believed to be a possible drug manufacturing site in Ashford Grove, St Clair on August 7.
Police seized six kilograms of methamphetamine, or "ice" as it is commonly referred to.
Following the search warrant, police arrested a woman and man, both aged 31, from St Clair.
They were charged for their alleged involvement in commercial drug supply and refused bail.
The woman will appear in Penrith Local Court this week while the man is due in Penrith Local Court on October 4.
