Janette Marsh was arrested at her Lakeview Pde home on Thursday morning, five weeks after her son and husband, Daniel and Robert Bojlevski, also left the address in the back of caged police cars.

Police allege Marsh, along with both Bojlevski men, enlisted family members and criminal associates to run commercial quantities of cocaine and marijuana between Sydney and the South Coast.

The family is accused of setting up safe houses in Primbee, Wollongong and Port Kembla, manned by henchmen with limited or no criminal history.

To avoid detection they allegedly use encrypted ciphr phones to communicate and covered the costs of hire cars for their runners.

They are also allegedly recorded paying the utilities on at least one of the Wollongong safe houses.

Police allege Marsh recruited two men with intellectual disabilities to store cash and drugs, and also used the men as her husband's driver, all while serving - on paper - as their carer.

According to documents considered by Wollongong Local Court on Friday, Marsh, who has has collected government payments since at least 2018, is now under investigation by Centrelink and the National Disability Insurance Scheme.

She allegedly continued to meet with "significant criminal entities within the Illawarra" even after the arrests of her husband and son, at times holding talks on her front lawn to avoid the possibility of her conversations being recorded.

Marsh's arrest is the sixth resulting from an investigation by Strike Force Axon, which has had the family and others under technical and physical surveillance since December, with the Bojlevskis allegedly flagged as key players.

The Bojlevski men have been refused bail over serious drug charges.

While Marsh has no prior criminal record, her husband and son have allegedly been involved in the supply of drugs since 2012.

Police allege Marsh and both men used runners to deliver drugs between Sydney and Batemans Bay to reduce the likelihood of the direct members of the Bojlevski family being caught carrying drugs or cash.

Police allege the family are unemployed and on Centrelink benefits but "live beyond their means", and have also been shown to gamble at venues including The Star Casino and locally, as a way of laundering money.

"It is believed the accused and both co-accused have access to fund which far exceed those available in [their bank accounts]," the court documents alleged.

"Police will show that the accused was an active and willing participant in a well-organised criminal group, to the point where she was couriering prohibited drugs and arranging for the supply of prohibited drugs in the Illawarra, Sydney and South Coast on a regular basis.

"The cash from the illegal activities has allowed her to purchase expensive luxury clothing items as well as the family vehicles which are also luxury items."

Police allegedly found $67,000 cash and a prohibited firearm in a "sophisticated 'hide' within the home of accused associates.

Marsh is charged with participating in a criminal group and contributing to a criminal activity, knowingly directing activities of a criminal group, receiving material benefit derived from the proceeds of crime, knowingly dealing with the proceeds of crime, supplying an indictable to commercial quantity of prohibited drugs and recruiting people to engage in a criminal activity.

In court, police prosecutor Sergeant David Weaver said the case against Marsh was strong, noting the police investigation was lengthy and involved telephone surveillance and recordings of her supplying drugs.

Defence laywer Nathan Campbell submitted the case against his client was weak as the alleged police documents tendered to court lacked "particulars" and included "vague unqualified opinions of police" such as exact details of Marsh's involvement.

Mr Campbell also said Marsh could have had other money to explain her lifestyle or tax record.

He repeatedly claimed the allegations were "reckless submissions to mislead the court", before adding his client denied all the claims.

Mr Campbell said there was no evidence of Marsh being a flight risk as she remained in the area after her husband and son were arrested.

He said his client had strong ties to the local community, needing to be at liberty to carry out her carer duties to support her daughter, who the court heard was spending a year in a drug and rehabilitation centre.

Magistrate Gabriel Fleming said the documents were a summary of alleged facts and were not evidence and therefore did not go into specific details, however did note there was some "vagueness".

Magistrate Fleming granted Marsh bail noting her nil criminal history and community ties. She must live at her Primbee home, report daily, not consume drugs nor go to known safe houses, not apply for a passport and offer a $5000 surety.

The case was adjourned to December 1.
