A Sydney man who stabbed his friend in the chest during a drug-fuelled stay in an Airbnb rental in the Blue Mountains has been jailed for at least seven-and-a-half years.
Henry Charles Walcott, 30, was found guilty of manslaughter by a NSW Supreme Court jury in February after attacking Cameron Bradley with a large kitchen knife at the Leura property in November 2016.
Justice Robert Allan Hulme on Friday sentenced the killer to a maximum of 10 years in jail with a non-parole period of seven-and-a-half years.
The pair had barely slept and consumed drugs including cocaine, GHB and ice during their two-night stay at the house before Walcott tackled Mr Bradley and stabbed him several times.
"But when seeing that these attempts had been fairly futile, I noticed that there was a very clear path for the neck area, so I took it trying to cut across," Walcott later told police.
The final and fatal blow punctured the victim's upper chest and ascending aorta. He died almost instantly.
Walcott told police Mr Bradley had said "only one of them would be leaving the house alive" and made other verbal threats during their time at the Airbnb rental owned by a friend of Walcott.
After noticing Mr Bradley was in "an aggressive sort of mode", Walcott said he grabbed a knife, made his way to the front door and then tackled his friend to the ground.
The pair struggled for more than a minute before the fatal knifing.
Walcott then dragged the body to the bathroom, smoked a few cigarettes and called police.
Justice Hulme said Walcott had a range of non-violent means of diffusing the situation or removing himself from the perceived threat of his friend.
"While I must accept that the offender believed that it was necessary to do what he did in order to defend himself, his response was grossly disproportionate and unreasonable," Justice Hulme said on Friday.
"While Mr Bradley may have been verbally threatening, it was the offender who initiated physical violence."
The victim's eldest brother said Mr Bradley was loved and his death had deeply affected his family and friends.
"His life should not be devalued because of the fact that he struggled with his mental health and with drug addiction," Andrew Bradley said in a victim impact statement, presented to the court.
With time already served, Walcott is due for release in October 2025.
