Shane Jaimeson French, 47, was one of two men arrested by Strike Force Rawlinson detectives who executed three search warrants at two homes and a business in Nowra on Tuesday, August 25.

Police allegedly located and seized cannabis, cocaine and more than $42,000 cash in the raids.

French, who runs the City Muffler Centre, is charged with 11 offences including five counts of supplying a prohibited plant, two counts of supplying cannabis, three counts of supplying a prohibited drug and participating in a criminal group, contributing to criminal activity.

It is alleged he supplied cannabis on a number of occasions between July 18 and August 25 this year and had also allegedly supplied methylamphetamine, or as it is known ice, and cocaine.

French did not appear in Nowra Local Court on Wednesday, August 26 before Magistrate Gabriel Fleming.

No pleas were entered to the charges, with his solicitor Ruth Ferguson indicating French would be making a bail application at his next appearance, which is set down for September 4.

Police prosecutor Andrew Kingston told the court the matters had been referred to the Department of Public Prosecutions.

Magistrate Fleming formally refused his bail.

A second man charged during the raids, 41-year-old Joseph Mouawad, of Nowra, applied for bail but was also refused.

Police allege he was an "upline supplier" to Mr French and a number of other men.

He is charged with 13 offences including four counts of supply prohibited plant, seven counts of supply cannabis, supply prohibited drug and knowingly direct activities of criminal group.

Mouawad sat calmly as he appeared via audio visual link from the Nowra Police Station, while his solicitor, Elias Khouzame, appeared from Sydney.

Mr Khouzame questioned the "strength" of the prosecution's case, pointing out what he said were a "number of inconsistencies in the facts", making particular note of the lack of definitive quantity of the alleged amounts of drugs supplied and "no drugs had been intercepted".

The court heard Mouawad and his wife run a Jim's Carpet Cleaning business, with Mouawad actually using his work vehicle, complete with company logo, to allegedly transport and transfer the drugs.

Facts tendered to the court allege Mouawad supplied 26 kilograms of cannabis between June 19 and August 25 this year.

The court heard police used a variety of surveillance techniques, including electronic, telecommunications recordings and physical surveillance during the operations, and intercepted multiple conversations between French and Mouawad where police allege at times "coded messages" were used to discuss and organise drug supply.

Mr Khouzame raised concerns regarding his client's health, highlighting he suffers from hypertension or high blood pressure, was overweight, had gout and high cholesterol and the fact he was listed for elective surgery in September, something he had been waiting several months for.

"With concerns over COVID-19 and my client's ongoing health issues I ask he be granted bail," he said.

He outlined a number of strict bail conditions his client was willing to undertake, resulting in "virtual house arrest".

Prosecutor Andrew Kingston told the court, the case "was strong", facts tended to the court showed a "number of co-accused had been arrested".

"This is not an insignificant amount of drugs," he said.

Magistrate Fleming disputed claims of lack of facts, saying while she had not seen the whole brief or detailed witness statements, she did not accept the fact the prosecution's case was weak.

"These are very serious matters and will go to the district court," she said.

"The community sees drug supply as a serious matter."

She denied the bail application and Mouawad will reappear in court on October 26.
