Gerard Baden-Clay has been found guilty of murdering his wife and been sentenced to life in jail.
A Brisbane Supreme Court jury delivered the unanimous verdict after deliberating for about 21 hours.
Allison Baden-Clay's body was found on a Brisbane creek bank in 2012.
The decision comes on the 21st day of Baden-Clay's trial.
Baden-Clay clenched his jaw and closed his eyes as he heard the jury's verdict.
He was lead away shaking after the jail term was announced.
Justice John Byrne said Baden-Clay had shamelessly pretended to search for his wife, and had used a razor blade to disguise what were really the marks of Allison's finger nails on his face.
He said Baden-Clay took his wife's body and dumped it at a nearby creek, and then put in place, and persisted in, a deception plan.
Baden-Clay had also invented the idea of a drug overdose as a ruse about what had really happened to Allison, and he'd shown a profound absence of remorse for his crime, Justice Byrne said.
He'd gone on to besmirch Allison's memory during the trial.
“You have no criminal history but you are definitely not of good character,” Justice Byrne told Baden-Clay.
“You took a devoted loving mother from her three girls, blighting their lives.”
A cheer from Allison's family erupted in the court as the jury verdict was delivered.
Allison's sister Vanessa Fowler wept and clasped her hands, and whispered “thank you” to the jury.
Allison's mother Priscilla Dickie read a victim impact statement to the court.
“I'm grieving over the late Allison June Baden-Clay,” she said in a shaking voice.
“My daughter was a wonderful mother, a devoted wife, a caring daughter and loving aunt.
“One of the last things Allison did was to leave her marks on her husband,” Mrs Dickie said, referring to scratches her daughter left on Baden-Clay's face on the night she died.
She said Allison had so much to offer her family and her three young daughters, but all that had been taken away.
She said her family had been sentenced to a lifetime of grief.
“It devastated me to know Allison was living in a troubled relationship,” Mrs Dickie said.
She said Baden-Clay had betrayed her daughter and made a mockery of their marriage.
“The pain does not go away,” she said.
She said her life now revolved around Allison's three daughters, and she said their courage had astounded her.
“Their resilience to this tragedy is a result of her guidance and love,” Mrs Dickie said.
“The girls will never see their mother again. They've been condemned to a life sentence without the love and companionship only a mother can give.”
“To kill your wife, to take away a mother and to still show no remorse has to us been one of the saddest and most distressing facts from this murder,” Mrs Dickie said.
She said the impact has completely and dramatically changed the rest of her life, her husband's life and the lives of Allison's children.
“Allison did not leave her girls. She had so much to offer them,” she said.
“Not being given the opportunity to say goodbye, hug or tell her how much we love her is shattering .... and the pain does not go away.”
Baden-Clay wept as he listened to Allison's mother.
Allison's father Geoff Dickie has also told the court of his heartbreak, saying the wonder of his life had been taken away.
He said he knows his daughter would have had the strength to fight hard to the very end as her life was taken.
He said he can't sleep any more and the agony of his daughter's fate torments him every day.
Mr Dickie said Baden-Clay had left a black hole in the lives of so many.
“The murder of our daughter ... leaves an enormous black hole in our lives from which I will never recover,” he told the court.
He told of still finding it hard to sleep and how he was haunted by the image of the moment his daughter was attacked.
“I know she would have found the strength to fight as hard and long as she could until the end before she was murdered,” he said.
He vowed to raise his three granddaughters in the way Allison would have wanted, and that was a great privilege.
“Our lives will never be the same until the day I die,” the grieving father told Baden-Clay.
He said a father's duty was to protect and care for his daughter.
“I've failed in my duty and I'll have to live with that,” Mr Dickie said.
He said he gave Baden-Clay permission to marry his daughter but never gave him permission to betray.
“We accepted you into our family and you abused our trust with your lies and deceits,” he said.
Allison's sister whispered the word “bastard” as her father told of giving his blessing when Baden-Clay had asked for Allison's hand in marriage.
Baden-Clay shook and wept, with his eyes closed as Allison's sister Vanessa Fowler told Baden-Clay he was guilty of the most heinous crime.
“My sister, for the first time since she married you, has come out on top,” she told the court.
She said her sister had been ridiculed, degraded and belittled since her death.
