Sami Esko Hamalainen had pleaded guilty to recruiting an associate to intimidate former Rebels bikie John Salafia, and to assisting an unknown person knowing they had committed murder.

The 45-year-old was already found guilty of being an accessory after the fact of Mr Salafia's murder on the NSW south coast in June, 2013.

Justice David Davies on Wednesday in the Supreme Court sentenced Hamalainen to a maximum of two years and eight months for the crimes, but having already served his time in custody was declared "free to go".

Hamalainen had been a member of the Rebels' Ulladulla chapter for more than 10 years when he organised with then-president of the club's Sydney chapter Robert John Stewart McCloskey to intimidate Mr Salafia at his Kings Point home.

The Rebels believed Mr Salafia was supplying members' addresses, including those of Hamalainen and McCloskey, to the rival Comancheros Motor Club.

Hamalainen recruited McCloskey to scare his long-time acquaintance Mr Salafia, knowing the intimidation would likely involve "more than just words," but that he never intended for him to be killed, Justice Davies said.

Hamalainen had been an avid car-buyer with more than 100 in his possession at one point and purchased a white Subaru Forester "getaway car" to be stashed in bushland.

McCloskey then drove his "crew" to Mr Salafia's residence where he lived with his family. He was shot three times in the head and chest moments after answering the door to a group of about two or three men.

Afterwards one of the assailants told McCloskey: "He was screaming and yelling ... and then I shot him in the head and he stopped moving".

The car was driven back into bushland and burnt, and Hamalainen subsequently became aware of the murder.

He instructed an associate to warn the Bawley Point man he purchased the Subaru from not to tell police he had done so. He later arranged for a car trailer to move the burnt-out car further into the bush away from police detection.

Although the Subaru was not found by the police for a week, there is no evidence that the hiding of it delayed the investigation into the murder," Justice Davies said.

Hamalainen did, however, endeavour to conceal the existence and whereabouts of the car used in the murder, and tried to hide his involvement in it, he said.

Hamalainen did not give evidence during his trial but did express remorse in an affidavit to the court.

"I understand that significant pain and suffering has been inflicted as a result of these offences and it is not something I ever wanted to occur," it read.

The court heard about Hamalainen's disrupted upbringing with foster carers he believed were his biological parents until aged 18.

After disagreements with two step-fathers he was kicked out of home as a teenager and began offending by the age of 16.

He joined the Rebels in his early 20s and found a "a sense of acceptance, family and stability that had been missing in his life".

His prospect for rehabilitation is reasonable and his risk of reoffending is considered low.
