Steven Anthony Dunne, 27, of Youngtown and Paul Lance Broad, 28, were sentenced in the Supreme Court in Launceston last week in relation to the attack on a 57-year-old man on June 17, 2019.

The incident stemmed from "bad blood" between Dunne and the son of the victim, resulting in earlier incidents of provocation in which the pair would perform burnouts in front of each other's houses.

This resulted in the victim's father installing CCTV cameras at his Brooklyn Road house.

On the day of the attack, Dunne, Broad and a third man drove to the house with the belief that the victim's son had performed a burnout in front of Dunne's house earlier that day. The victim's son was not at the house at the time.

They started doing a burnout and the third co-accused allegedly attacked the victim's parked vehicle with a log splitter or axe. The victim then emerges from the house armed with a baseball bat and struck the car doing the burnout.

Dunne and Broad then approach the victim, who stood his ground. Broad "physically engages" him, before Dunne took the log splitter from the third man and struck the victim's legs multiple times.

Broad held on to the victim and wrestled the bat from his hands while Dunne continued to strike him to the upper body and head. The three men then fled the scene, leaving the victim seriously injured. His wife witnessed the attack, which was also captured on CCTV.

The victim suffered lacerations to the face and abdomen, vertebrae fractures and dental avulsions with the required removal of six teeth and possibly three more. He required multiple rounds of surgery.

The court heard the victim feared he would be killed in the attack.

Broad had a prior conviction for attacking a neighbour over a "perceived grievance", while Dunne had convictions for firearm offences and drug matters. The third co-accused is yet to stand trial for their alleged involvement in the attack.

Justice Michael Brett said the injuries could have been far worse.

"The attack perpetrated by you both was brutal, cowardly and sustained," he said.

"It was carried out in a group against a single victim, for no good reason and it resulted in severe injury."

Dunne was given a discount on his sentence for agreeing to give evidence in the trial of the third man. He was sentenced to two years' jail with a one-year non-parole period, starting from July 9.

Broad was sentenced to two years and six months' jail with a non-parole period of 18 months, starting from June 19, 2019.
