Finks bikies Sione Hokafonu and Poiva Sita are standing trial for the attempted murder of Mongol bikie Rocco Curra, who was shot four times in the head and chest.
Hokafonu is accused of being one of two shooters who fired 11 or 12 times at Mr Curra, as he sat in a car in a suburban street.
He believed he was meeting a woman in the evening of August 1, 2019.
Sita is alleged to have been the getaway driver. Another man, Tavita Sua, is also accused of being one of the gunman and his case is being heard separately.
Footage played to jurors showed a silver BMW park in front of Mr Curra's car before two men jump out and fire a series of shots into the vehicle, which struck him four times.
It's alleged the attack on Mr Curra was a revenge attack by the Finks Motorcycle Gang, prosecutor Neill Hutton told jurors in Victoria's Supreme Court on Thursday.
He alleged it was in retribution for the shooting of Hokafonu in the foot days earlier.
That incident was apparently in retaliation for an incident at a shopping centre pub where a Mongols associate had his jumper taken as a "trophy", Mr Hutton said.
When asked why Mr Curra had been shot, Hokafonu allegedly told an associate "blood for blood".
Mr Curra stayed in his car for six or seven minutes after being shot in the head and chest before trying to drive away. He drove one house block and crashed into a tree.
He staggered toward a house and lay in the garden for a time before managing to knock on the door where residents took him in and called police.
"He's very lucky to survive," Mr Hutton said.
At a meeting of the Finks the following day, the shooting of Mr Curra was generally celebrated by members who believed he had been killed, Mr Hutton alleged.
Jurors heard Mr Curra had been lured to the Bulleen street under the belief he was meeting a woman who had reached out to him over Instagram.
It's alleged Mr Curra was set up only because he was a member of the Mongols.
In the lead up to the shooting there had been several incidents between the two clubs, starting with a Mongols associate having his "Support Your Local Mongols" jumper taken by members of the Finks during an incident at a Sporting Globe hotel at Fountain Gate shopping centre. Following that incident Hokafonu was shot in the foot, allegedly by members of the Mongols.
After the shooting the stolen silver BMW allegedly carrying Hokafonu and Sita was set on fire and they were driven away in a second BMW.
Sita's brother, Joseph Opapo, is alleged to have been the driver of that car and has been charged with intentionally causing serious injury in circumstances of gross violence.
Mr Hutton said a gun used in the shooting was found in Hokafonu's possession five months later.
