Salim Nehme, 26, was denied release after making his first bail application in Wollongong Local Court on Wednesday.

He was charged following a lengthy covert police operation that netted $1.5 million in cocaine, meth and MDMA.

Nehme and co-accused Simon Suleski, 23, were arrested on December 16 last year in Unanderra during sweeping raids.

Documents previously tendered to court during Suleski's bail application allege the men were involved in a "sophisticated, well-planned and meticulously organised criminal syndicate" responsible for supplying a large commercial quantity of cocaine, methylamphetamine, MDMA and ecstasy.

The Wollongong criminal investigations drug unit seized up to $1.5 million in drugs including more than 1.2kg of cocaine, almost 850g of methylamphetamine and a kilogram of MDMA and ecstasy tablets during the six-month investigation that began in July last year.

Police allege Nehme and Suleski were responsible for the negotiations, sourcing and supplying of the drugs, working "closely as partners" and both received "financial benefit".

Nehme was allegedly captured through encrypted services under the user ID, the 'Godfather', describing the operation as "the 7-eleven of the drug trade, a one stop shop".

As part of the investigation, police allege they uncovered the code names used by the syndicate including "rack" which referred to cocaine, "fry" meant methylamphetamine and "pills" for MDMA or ecstasy.

Police allege the men used sophisticated methods to avoid arrest, including multiple motor vehicles to attend drug transactions, telecommunication services under false details, encrypted devices, code names and different meeting locations for the supply and collection of drugs.

Telephone intercepts, surveillance devices, controlled operations and physical and electronic surveillance were used by police to catch the alleged drug suppliers.

Police allege between September 30 and December 16 an associate was supplied drugs from Suleski and Nehme, totalling $566,700.

Police will allege one of the largest drug transactions occurred on November 30 after an associate began negotiations with Nehme for the sale of 482 grams of cocaine, 482 grams of meth and 3000 MDMA pills in exchange for $266,800.

Police allege Suleski and Nehme went to an address in Unanderra and made the transaction on December 16 at about 2.30pm.

Nehme was charged with four counts of supply prohibited drug - large commercial quantity, six counts of supply prohibited drug - commercial quantity, five counts of supply prohibited drug - indictable, three counts of supply prohibited drug, and deal with property proceeds of crime.

Suleski was charged with four counts of supply prohibited drug - large commercial quantity, five counts of supply prohibited drug - commercial quantity, seven counts of supply prohibited drug - indictable, four counts of supply prohibited drug, and deal with property proceeds of crime.

In court on Wednesday, Nehme's lawyer Robert Daoud submitted conditions could mitigate bail concerns and his client could live with a family member who would support him.

He did concede the prosecution case against Nehme was "strong".

Magistrate Susan McGowan said the case was "complex" and refused to grant bail.

Nehme and Suleski's cases will return to court on June 9.
