Alleged South Coast chapter secretary Matthew Douet and gang associate brothers Samiu and Siaosi Tukuafu were arrested on Thursday following raids at two homes in Albion Park and Dapto.

The men came under police notice after an investigation, named Operation Ironside, was launched into an encrypted communication network, ANOM used by organised crime groups in Australia.

An Australian Federal Police-led operation investigated the encrypted communications from organised crime members were decrypted from a platform covertly run by the FBI.

Douet, 31, was charged with 42 drug supply charges and two counts of knowingly dealing in the proceeds of crime on Thursday.

Samiu Tukuafu, 19, was charged with four counts of supply prohibited drug, knowingly or recklessly direct criminal group assist crime, deal with property proceeds of crime, and supply prohibited drug.

Siaosi Tukuafu, 20, was charged with knowingly or recklessly direct criminal group assist crime, two counts of supply prohibited drug, two counts of deal with property proceeds of crime, supply prohibited drug (commercial quantity), and deal with proceeds of crime.

Documents tendered to court said police were monitoring the men, along with alleged Comanchero South Coast Chapter sergeant at arms Emmanuel Vamvoukakis between March 2020 and June 2021.

Vamvoukakis was arrested and charged in a raid at his West Wollongong home in June for allegedly trying to import cocaine from Greece.

The documents said police confirmed Douet was the Comanchero's South Coast Chapter secretary, Siaosi was a nominee of the chapter and Samiu was an associate of the gang.

Douet and the brothers lived at the same Harbour Boulevard home in Shell Cove and police executed a search warrant there on June 6 and seized five mobile phones.

As part of the investigation, Samiu was identified as using the encrypted mobile device with the username, "JDoe" while his brother used "Pillowcase123" and Douet used the name "Glen20".

Police allege Douet established a "co-ordinated and extensive criminal network" and had direct control over the Tukuafu brothers and others.

Police allege the gang was used to facilitate the supply and ongoing protection of Douet's criminal network in the supply of prohibited drugs, enforcement of drug distribution territory and public acts of violence including debt collections.

Police allege that while Douet was serving parole for 12 months from October 2020, he breached his "non-association" condition with gang members more than 2000 times.

"I won't be wearing anything again if they want me to cover up club stats to prove I have distanced myself I'll do it. I'm going to get smarter for myself brother can't let pride stand in the way of it all," Douet allegedly said in February this year.

The documents said Douet and Vamvoukakis were allegedly trying to strengthen the presence of the outlaw motorcycle club on the South Coast and to ensure the protection of its drug-running territory, with Douet saying to Vamvoukakis, "brother pls we need build up a solid crew here" in July 2020.

"Hey bro I been doing my research on these lads before I meet them apparently one a shooter n one a stabber. They both mad Aussie boys," Douet alleged messaged Vamvoukakis.

The documents said police obtained information from the ANOM platform allegedly confirming Douet sourced various quantities of drugs from different sources including Vamvoukakis.

It is alleged Douet purchased no less than 180 ounces equating to 5.10 kilograms of cocaine on at least 31 occasion from Vamvoukakis between March 17, 2020 and June 4, 2021 with for $1.2 million.

On one occasion on August 30 last year Vamvoukakis allegedly supplied 20 ounces of cocaine to Douet for $110,000 and a few days later Douet again requested 20 ounces and one pure ounce from Vamvoukakis for $115,000.

Police allege Douet and Vamoukakis met on September 2 and exchanged the 20 ounces of cocaine in four packs containing five ounces each.

At one point the Vamvoukakis allegedly talked to Douet about one of his customers being arrested with two ounces of cocaine and he was concerned the person may "roll" on him for an ongoing supply of 10 ounces.

"I'm actually worried about Joel I'm hearing he got done with 2 okas in Bellambi...if he rolled on me they got me for ongoing supply prob 10 okas....I hope he didn't roll on me," Vamoukakis allegedly said.

"If they had that on u I reckon they would have got u when he was away...that's enough to get 5 years easy," Douet allegedly replied.

"Unless they are trying to get a big one they just sitting and waiting...I don't know my head doesn't stop," Vamoukakis allegedly said.

"If they had ongoing that's enough bro...there aim is to get us off the street n that would def be enough," Douet allegedly replied.

"Yeah that's what I think lets see what happens when he gets out," Vamoukakis allegedly said.

Police allege Douet directed and supplied no less than 12 ounces of cocaine on at least five occasion to Siaosi Tukuafu so he could on supply it between March 12, 2020 and June 4, 2021 for $109,000 in proceeds.

Police allege Douet supplied 14 ounces of cocaine on than four separate occasions to Samui Tukuafu between March 17 and June 4 for $71,5000 in proceeds.

The documents said an ounce of cocaine could be sold for $5500 to $7500 and a kilogram could cost between $150,000 and $230,000.

In court on Friday, police prosecutor Sergeant Ben Bragger strongly opposed bail noting the very serious allegations, adding the prosecution case was strong given the "sophisticated controlled police operation". He also said "drugs kill people" and the men had an alleged role in supplying it.

"Samiu may not be a major player, but that does not diminish that he is a player and there is always a risk when someone is a player," he said.

Samiu's defence lawyer Graeme Morrison said his client's role was "at the lowest in the whole operation" and noted he had a limited criminal record and there was "no possible way" Samiu could continue to allegedly supply drugs as the principals of the operation had been arrested.

Magistrate Michael O'Brien essentially imposed house arrest when handing down strict bail conditions.

Samiu must live with his mother in Worrigee, report daily, abide by a night curfew and only go outside with his mother among other conditions.

Saiosi was refused bail due his criminal record that included violence, and associations with other criminals despite defence lawyer Analise Ritchie saying her client maintained his innocence, would spend a long time in custody on remand and he would miss the birth of his child.

Douet did not apply for bail and it was formally refused.

The cases will return to court in October.
