A Queensland man accused of stabbing a man 17 times slashing his jugular vein, threatened to knife a bystander who intervened to stop the brutal fight, a court has been told.
Levi John Stephen Elliott, 33, was celebrating his birthday at the Brothers St Brendan's Leagues Club in south Brisbane when he allegedly fatally stabbed Adam Woodward, 35, on August 24, 2018.
Elliott has pleaded not guilty to murder in the Brisbane Supreme Court claiming he feared for his life and acted in self-defence.
On the second day of his trial, security footage taken from inside the club shows Elliott clearly gesturing to Mr Woodward pointing toward the club's security system.
The court was told there was "no love lost" between the pair with Mr Woodward warned he would end up with a "knife in his throat" during an earlier scuffle.
Prosecutor Caroline Marco said Elliott believed the building scaffolder had disrespected his sister after a "one-off sexual encounter".
After months of antagonism, Elliott purchased a butterfly knife from online retailer Wish - a weapon delivered 11 days before the deadly fight.
The night of the confrontation, footage showed Elliott had sought out Mr Woodward who was drinking separately with friends.
Video footage showed Elliott tracking the rival group during the night with several people warning him to "back off" as he taunted Mr Woodward.
Just before 9pm, the growing tension erupted with Elliott daring Mr Woodward to follow him outside saying: "I want to hurt you, come on. I want to hurt you, come on where there are no cameras".
"Levi was swearing at Adam, he was telling him to come away from the clubhouse and come outside," witness Sydney Liu Liu told the court on Tuesday.
"Levi was yelling at Adam, calling him a pussy.
"They were both swearing and Adam followed Levi out on the street."
The confrontation spilled outside the club and onto the roadway, out of range of the club's security cameras, the court was told.
"Levi was saying 'come on, come on'. They were on the road when Adam pushed Levi and he pushed him back," Mr Liu Liu said.
"Levi went to throw a punch and missed and Adam punched him and hit him on the chin ... you could hear it."
The pair continued to exchange blows before Elliott was thrown to the ground.
"Levi was trying to block the punches while punching with his right hand," Mr Liu Liu aid.
"Adam was on his knees on top of him, punching him ... but he got slower and slower.
"I saw Levi punch toward Adam's neck - he was punching sideways. It was pretty quick. After it was all over, I saw the knife in his hand."
Mr Liu Liu moved in to separate the pair and stop the fight.
"I grabbed Adam off Levi. I pulled him off and he collapsed on the road.
"I was concentrating on Levi, I saw that he had a knife and he said he would do the same thing to me.
"He said 'stay away from me or I will do the same thing that I did to Adam'."
Elliott fled on foot, ditching the butterfly knife in a drain before later being found by police hiding in a front yard.
Mr Woodward suffered 17 wounds including the fatal laceration to his neck that transected his jugular vein that caused massive haemorrhaging before collapsing his left lung.
The trial before Justice Glenn Martin set down for a week, continues.
