A man accused of being the upline supplier of a drug ring operating out of an automative store in Port Kembla has been refused bail.
He is the fourth man to be charged in connection to the alleged Illawarra drug operation.
The shop on Military Road was raided at the end of September after a strike force was established to investigate the supply of prohibited drugs in the Illawarra.
During a search of the store, Lake Illawarra detectives allegedly found almost half a kilogram of methylamphetamine - which has an estimated potential street value of $80,000 - drug paraphernalia, a firearm and ammunition.
Two 27-year-old men and a 39-year-old man were arrested and charged with commercial drug supply offences in connection to the seizure. They remain before the courts.
Following further inquiries, investigators from NSW Police's drug and firearms squad stopped a white Toyota Camry in Penrith about 4.15pm on Tuesday.
A search of the car revealed $65,000 cash, police said.
The 33-year-old male driver and 32-year-old male passenger were arrested and taken to Mount Druitt Police Station, where the passenger was released pending further inquiries.
A short time later, investigators executed a search warrant at the 33-year-old man's Guildford home and seized 16kg of MDMA, 3kg of methylamphetamine, 1kg heroin, 1kg cocaine and $320,000 cash.
The estimated street value of the drugs is in excess of $1.4 million.
The 33-year-old man was charged with five counts of large commercial drug supply and deal with proceeds of crime.
Police will allege the man was the upline supplier of a syndicate operating out of the automotive store in Port Kembla.
He was refused bail to appear in Mount Druitt Local Court on Wednesday.
Investigations under Strike Force Mote are continuing.
