Joel Clavell screamed that he wanted to become a martyr during the incident at Richardsons Bend on June 12 last year, and threatened to cut the heads off police while armed with a hatchet.

His older brother, Joshua, had been shot by police moments earlier after driving a Holden Barina into an unmarked police vehicle, pushing it back three feet and throwing an officer backwards into rocks.

The brothers quickly jumped out of the car while both armed, Joshua with a knife and Joel with the hatchet.

The injured officer pointed his gun at Joel and screamed at both men to drop their weapons before firing three shots at Joshua, which immediately dropped him to the ground.

Other officers approached and tried to contain Joel and negotiate his surrender, repeatedly telling him to disarm himself.

Footage taken on police body cameras during the ordeal shows the younger brother ducking behind the rammed police vehicle for several minutes during the standoff, as police took cover behind the damaged Barina.

Joshua could be seen laying on grass, at times moving his leg.

Joel refused to obey police and repeatedly told them to shoot him while ducking behind the rammed police vehicle.

He called the officers "dogs" and "mutts" and told them to put their guns down so he could chop their heads off.

Officers tried to use capsicum spray and a taser to stop him, but Joel sprinted towards a group of officers.

He was shot by two officers, only five or six feet away from the members, and fell to the ground still holding his weapon.

Despite the aggressive behaviour by the brothers - who have a hatred of police - the County Court on Thursday heard a police officer had likely saved Joel's life by applying a tourniquet to his bleeding leg.

One of the bullets hit him in the left thigh, severing his femoral artery and causing extensive bleeding and unconsciousness.

The younger brother required 16 units of whole blood, three units of frozen plasma to assist with clotting, and platelets, as he was driven to Albury hospital.

One bullet skimmed the lining of his heart and he still has bullet fragments in his shoulder and abdomen.

The court heard it was lucky - for all involved - that he survived.

The court heard Joel had hit his head on the Barina when it rammed the police vehicle, which in itself could have killed him.

Older brother Joshua - who had been wanted by counter terrorism police - was forced to use a colostomy bag after the incident, and has permanent scars to remind him of what occurred.

Judge Martine Marich, who heard sentencing submissions for both men on Thursday, praised police for helping the pair after the incident, particularly Joel.

"The calm delivery of medical assistance was deeply admirable," she told his lawyer.

"Your client must have been in real distress at that time."

Counter terrorism police had been heading to the pair's residence in David Street in Albury to arrest Joshua on an outstanding warrant on the day of the shooting, which led to a chance encounter on the way.

Both men had been camping at Richardsons Bend for about a month for Ramadan and the officers coincidentally spotted them in the Barina at the nearby BP service station.

The Rutherglen officers involved in the shooting had been called in to assist the counter terrorism officers.

The court heard the matter wasn't driven by Islamic extremism, but rather a hatred of police.

Judge Marich said she couldn't find, beyond reasonable doubt, that the incident was religiously motivated.

While Joshua, now aged 31, has served time in jail, the incident was the first time 20-year-old Joel had come to police attention.

He had "got through a childhood you may not wish on your worst enemy', the judge noted.

The court heard Joel could have just put his weapon down.

Judge Marich wondered whether it was a case of someone demonstrating bravado or trying to go down in flames, or whether the 20-year-old was out of his depth.

A picture of a violent and chaotic upbringing was painted in court, with the pair's father Rodney Clavell considered the most wanted person in South Australia when he took his own life in a police siege in 2014.

The 46-year-old, who was a heavy drug user, killed himself with a pump action shotgun in an Adelaide brothel during a 12 hour siege.

The court heard Joshua had been caring for himself by the time he was in Year 10 and cycled through different care arrangements due to instability at home.

He spent a few months living with his dad when he was 17, but didn't enjoy being around him due to his drug use.

He underwent two major surgeries following the shooting with his care made difficult due to him being in custody.

His lawyer said his injuries would be a "savage reminder" of what he had done.

The 31-year-old was in NSW prison from August 31, 2019, to February 4, for stalking and larceny and served six months in Victorian custody after his arrest in Barnawartha North for breaching a corrections order.

The younger man's lawyer asked he be released from custody with time served and placed on a community corrections order.

Judge Marich appeared to be opposed to the idea, but ordered he be assessed for an order.

The pair will return court on June 15.
