Five men charged over the 2012 murder of Jason De Ieso have been remanded in custody after each briefly appeared in the Adelaide Magistrates Court this afternoon.
The men appeared by video link from custody and did not apply for bail.
A 26-year-old woman, who was extradited from Queensland last week, and a 31-year-old man from Salisbury Downs were also remanded in custody charged with assisting an offender.
Magistrate John Fahey granted an application by prosecutors to suppress each of the accused's names and images because police investigations are ongoing.
There was a strong police presence in court for the hearings with more than a dozen officers and detectives in attendance.
There were also large groups of supporters for each of the accused and the hearings had to be moved to a larger courtroom to fit everyone.
Outside court, Detective Inspector Billy Thompson said Mr De Ieso's family were pleased the arrests had been made.
"They are very pleased, but as I say this is just the start of the process, we have a lot of work to do," he said.
Police have previously said Jason De Ieso — who was shot dead at his panel beating business at Pooraka — was innocently caught up in a dispute between the Hells Angels and Finks bikie gangs.
They have said the 33-year-old's only mistake was maintaining a childhood friendship with a man who went on to become a Fink bikie.
CCTV footage from Mr De Ieso's Unique Custom Paint and Panel business, previously released by police, showed nine men walking towards the front of the workshop on the day he was shot.
Police have previously said at least six of the men were carrying guns and that they were hoping to make further arrests.
Outside court, Mr Thompson reiterated calls for anyone with information about the alleged murder to contact police.
"The time is now to come forward and talk to us and you can do that by contacting Crime Stoppers," he said.
The men will face court again on December 6.
