A man convicted of an hour-long shooting spree that terrorised a NSW Central Coast neighbourhood and left one man dead has been sentenced to 42 years in prison.
Bradley Jason Mark White, 42, was found guilty of seven charges, including murder, in Newcastle Supreme Court in October.
Justice Mark Ierace handed down the sentence in Newcastle Supreme Court on Friday.
For an hour on a late March afternoon in 2020, Cutler Drive in Wyong came under attack from a "haze of bullets" fired by two rifles by White from the front of his house.
Byron Tonks, 20, was shot dead while sheltering in a nearby house and two others suffered back and shoulder injuries from the bullets.
During the shooting spree, 13 people sheltered in the house where Mr Tonks died, including several infants.
Many more adults and children sheltered in neighbouring homes at the time.
White started the shooting spree after a 17-year-old neighbour arrived home playing "music loudly" in his ute.
White was under the influence of ice at the time.
He confronted the teenager, who then ran inside his home. The offender then set the teenager's ute on fire.
Soon after, the shooting spree started.
Mr Tonks came to a property on Cutler Drive after the 17-year-old had called him about what was happening.
He was shot dead while standing in the lounge room of the 17-year-old's home.
Multiple neighbouring homes and parked vehicles were also damaged by bullets during the shooting spree.
During sentencing submissions late last year, members of Byron Tonks' family said they had been left shattered and traumatised by the "senseless and callous" death of their son and brother.
Byron's mother, Cindy Tonks, sobbed through her victim impact statement as she described traumatising flashbacks she likened to "horror movie re-runs" in her head.
She told the court she and her husband, as well as their younger son, all witnessed the shooting and Byron's death that evening.
White's defence barrister Mark Hobart argued his client was "acutely mentally unwell" at the time and said that needed to be taken into account.
In the Crown's closing address, prosecutor Kate Ratcliffe rejected claims that White had a mental or cognitive impairment, arguing it did not fit with the evidence.
The jury ultimately found him guilty of seven charges in October.
In handing down his sentence on Friday, Justice Ierace said White's actions "clearly traumatised" the victims and that he had intended to cause significant harm.
Justice Ierace said White had intended to kill the 17-year-old boy during the shooting spree.
He acknowledged that White had received a brain injury during an assault in 2000 and had mental health problems.
He also said White had a "disturbed and troubled childhood," marred by violence and sexual abuse.
However, he said these factors did not mitigate the crimes White committed, only put them into context.
Justice Ierace sentenced him to 42 years in prison.
White's sentence has been backdated to when the offences occurred on March 17, 2020.
He will be eligible for parole on March 16, 2050.
