A NSW bikie who drove to a long-time acquaintance's home to intimidate him but ended up driving away the man's executioner could be paroled within two years.
John Salafia, 38, was shot three times in the head and chest moments after answering the door to his home on NSW's south coast on June 26, 2013.
Then-president of the Rebels' Sydney chapter, Robert John Stewart McCloskey, admitted driving three men to and from the Kings Point residence.
The Rebels believed Mr Salafia was supplying members' details to a rival gang, leading senior members to arrange for the "Johnny issue" to be sorted out.
In sentencing remarks made public on Thursday, Justice David Davies said the evidence didn't suggest Mr Salafia was to be killed but rather that he would be assaulted.
McCloskey was acquitted of murder in July.
Justice Davies found the 45-year-old had been alone in a car outside Mr Salafia's home for five minutes when he heard a single shot then four more.
A few minutes later, the three men returned to the car. One man, known as QR, loudly claimed Mr Salafia had shot first through the front door fly screen.
"I shot him in the chest, f*** he was a tough c***," QR said.
"He was screaming and yelling ... and then I shot him in the head and he stopped moving."
The trio, who'd also been armed with knuckledusters and at least one baseball bat, was driven by McCloskey back to a location near Batemans Bay.
"Murder being the worst of crimes, those who assist murderers to evade justice are also to be severely punished, as the maximum penalty provides," the judge said.
"At the present time, the deceased's killer has still not been brought to justice."
Currently serving a lengthy sentence for a public shooting, McCloskey was jailed for at least 13 months over Mr Salafia's death.
He'll be eligible for parole in May 2022.
The 18-month head sentence included a 40-per-cent discount for the early admission and McCloskey's assistance to authorities prosecuting "significant crimes".
Another senior bikie, Sami Esko Hamalainen, in September pleaded guilty to recruiting McCloskey to intimidate Mr Salafia and to assisting an unknown person, knowing that person had committed murder.
