An ex-Hells Angels meth cook who masterminded the gangland shooting of a former bikie associate has been jailed for over 13 years.
Michael Basanovic was on Wednesday imprisoned for his part in the January 2013 slaying of Zeljko "Steve" Mitrovic inside a western Sydney transport business.
Basanovic, 54, in December pleaded guilty to manslaughter as well as causing grievous bodily harm to Michael Bell, an office worker who was caught in the crossfire.
He was sentenced in the Supreme Court to 13 years and eight months' jail with a non-parole period of 10 years and three months.
Because he has been in custody since May 2013, he will be eligible for release in August 2023.
Basanovic, wearing prison greens, was unmoved in the dock as he was sentenced by Justice Richard Button.
In 2016, a jury convicted Basanovic of murder and sentenced him to a minimum of 21 years' jail, however his conviction was quashed on appeal.
During a re-trial, he pleaded guilty to manslaughter for hatching the plot to kill Mitrovic inside the bikie's Wetherill Park workplace before his son pulled the trigger.
Before their relationship soured, Justice Richard Button said that Basanovic had worked as a methamphetamine cook in partnership with Hells Angels heavyweight Mitrovic.
Justice Button described Basanovic as being "well entrenched in the criminal milieu" and whose "expertise as a 'meth cook' was highly valued" in the underworld.
Tensions eventually boiled over when Basanovic had feared that Mitrovic had wanted him killed and claimed he was acting in self defence.
"The offender decided to defend himself from the threat of fatal violence by 'getting in first'," Justice Button said.
"That is, by way of a planned, brazen, undisguised, fatal shooting, in front of witnesses, in broad daylight, at the workplace of the deceased."
During a heated confrontation Mitrovic had told the pair, "You're all f***ing dead" before the younger Basanovic repeatedly shot him in the chest.
Wade Basanovic was in 2016 jailed for 14 years and 6 months, with a non-parole period of 11 years, after being found guilty of manslaughter and grievous bodily harm with intent.
"Speaking very generally, it is sometimes the case that the individual who actually commits the criminal act is judged to be deserving of harsher punishment than his or her confederates," Justice Button said.
"But in this case it was the offender who was in dispute with the deceased. It was he who was the instigator of the joint criminal enterprise and it was he who provided the handgun to his son.
"In the circumstances, I assess the objective role of the offender as at least equal to that of his son, despite the fact that the offender never pulled the trigger."
