Two men are due to face court after more than $3 million in cash and 2000 litres of a chemical used to manufacture drugs were seized by police.
The men were arrested during dawn raids on Wednesday at properties in Sydney's southwest.
At a Bankstown unit police seized more than $3 million in cash and steroids and arrested the two men, aged 43 and 44.
In Yagoona, police allege they found a clandestine drug lab, and 2000 litres of a chemical used to make the drug known as GHB, or "liquid ecstasy".
Hazmat crews verified the scene was safe and police began dismantling the drug lab.
Strike Force Aphrasia was established in August to investigate the manufacture and supply of prohibited drugs in Sydney's southwest, leading to the Wednesday morning raid.
The 44-year-old man will face drug manufacture and supply charges as well as accusations he dealt with the proceeds of crime and directed the activities of a criminal group.
The 43-year-old man will face the same charges except for the direction of criminal activities charge, having instead been charged with participating in a criminal group and contributing to its criminal activity.
The two men are due to face Bankstown Local Court on Thursday.
