Borce Ristevski hasn't revealed how or why he killed his wife of nearly three decades and spun a "web of lies" about her disappearance, but could walk from jail in four-and-a-half years.
The Melbourne man was imprisoned for nine years on Thursday for the high-profile manslaughter of Karen Ristevski in 2016.
Ristevski, 55, must spend six years behind bars before being eligible for parole and, with time already served, could walk in December 2023.
The sentence was condemned by Karen's brother Steve Williams.
"Nothing is going to bring Karen back, but today was about justice and we didn't get justice today at all," he told reporters outside the Supreme Court of Victoria.
Justice Christopher Beale said he didn't have enough information to determine the severity of Ristevski's crime.
"Without knowing the level and duration of the violence perpetrated by you which caused your wife's death, I simply cannot say whether your offending was mid or upper range," he said.
Justice Beale said no sentence could undo the suffering of those who loved Ms Ristevski, condemning Ristevski's "rank deceit" and the lies he told police, friends and family, including the daughter who stood by him even after his guilty plea.
"You have not revealed how or why you killed your wife," he said.
"You may have turned off the road of deceit but you have not taken the high road of full and frank disclosure consistent with true remorse.
"In the days, indeed months and years, that followed you continued spinning your web of lies."
Ristevski acted as pallbearer at his wife's funeral, "playing the part of the innocent, grieving widower".
On June 29, 2016, Ristevski killed 47-year-old Karen at their Avondale Heights home before bundling her body into her Mercedes-Benz and driving to Macedon Regional Park, hiding his wife under logs, sticks and foliage.
The couple had been married for 27 years.
That evening, Ristevski told 21-year-old daughter Sarah the pair had an argument and he had no idea where her mother was.
Karen's remains were so decomposed when they were found eight months later, an autopsy was unable to reveal the cause of death and Ristevski has never offered an explanation.
Ristevski was initially charged with murder in December 2016, but Justice Beale ruled the evidence available could not prove murderous intent.
Instead, on the eve of his murder trial, Ristevski pleaded guilty to manslaughter, with the judge noting "you have finally accepted responsibility for killing Karen".
The Director of Public Prosecutions is yet to decide whether to challenge Ristevski's sentence and has 28 days to lodge an appeal.
Attorney-General Jill Hennessy declined to comment other than to offer sympathy to Karen's family and friends.
Victorian opposition leader Michael O'Brien described the sentence as "woefully inadequate", calling for a parliamentary committee to be established to review and reform Victoria's "broken sentencing laws".
No To Violence CEO Jacqui Watt said: "Does this sentence reflect community attitudes now that the community is more aware of the prevalence and serious nature of family violence? The answer is clearly no."
Despite her father's manslaughter admission, Sarah Ristevski stood by him, supplying a "glowing reference" for her dad.
It detailed the "unexplainable" love between herself and her parents, describing the trio as "inseparable".
Justice Beale sympathised with Sarah.
"Anyone with a modicum of compassion must understand that her predicament is an agonising one," he said.
