A "cowardly" young man who murdered his best mate with a machete in a Victorian national park has been jailed for 20 years.
Samuel Worthy, 21, attacked 20-year-old Joshua Kane from behind with the weapon during a hike at Mount Eccles National Park in January 2016.
Worthy and two friends, Lanie Snell, 35, and Stuart Campbell, 21, all pleaded guilty to Mr Kane's murder.
The trio brought Mr Kane to the national park under the guise of going for a hike before he was killed on the track to Lake Surprise.
In the Supreme Court on Tuesday, Justice Jane Dixon sentenced Worthy to 20 years behind bars for the "senseless" murder.
"This was a brutal, calculated and senseless attack on Joshua Kane," Justice Dixon said.
"You deceived him into going with you ... so you could carry out your attack.
"Once at Mount Eccles, you approached Joshua Kane from behind in a cowardly and despicable manner."
The killers returned to the national park the next day in a bid to conceal the crime, but they couldn't find the body.
Mr Kane's decomposing remains were discovered by police in scrub some way off the track about six days later, and the trio were soon arrested.
The judge said the murder was carried out for the "most insubstantial of motives".
She said Snell was angry at Mr Kane for speaking to her young children in a derogatory way, including once calling her son lazy.
Worthy had also developed animosity toward Mr Kane, the judge said, but he had been unwilling to speak about his motivation for the killing.
The pair had previously been best friends.
Worthy was ordered to serve at least 16 years in prison before being eligible for parole.
Snell was earlier jailed for at least 15 years for the murder, and Campbell was imprisoned for at least nine years.
