Robert Farquharson has been found guilty for a second time of murdering his three sons by driving them into a dam on Fathers Day.
After an 11-week retrial, a Victorian Supreme Court jury took three days to find him guilty of murdering Jai, 10, Tyler, seven, and Bailey, two.
As the verdict was delivered on Thursday, Farquharson trembled, shook his head and mouthed "no" as he looked to his weeping sisters in the court room for support.
His ex-wife and the boys' mother, Cindy Gambino, who was supported in court by her parents and new partner Stephen Moules, showed no emotion.
Ms Gambino's mother Beverley, however, collapsed outside court after the family rushed past a large media contingent without making comment.
She was quickly put into a taxi and whisked away.
One female juror was crying as the forewoman read the guilty verdict.
The boys died on Father's Day in September 2005 when Farquharson deliberately drove his car off the Princes Highway near Winchelsea, in Victoria's west, and into a dam.
Farquharson was given a retrial after his 2007 conviction and life sentence were quashed by an appeal court last year.
In his closing address earlier this month, prosecutor Andrew Tinney, SC, told the court Farquharson's resentment and anger toward his ex-wife "drove him to commit an almost unspeakable act of vengeance".
Mr Tinney said after murdering the children, Farquharson had the "delicious reward" of telling Ms Gambino about the deaths.
"In this case, in the end, your head, members of the jury, will clearly and strongly tell you something that your heart may not want to believe," he said.
"It is that the accused really did murder those three defenceless children; it is that a human being really can sink to such depths.
"You should find him guilty on all three counts of murder."
Farquharson's barrister Peter Morrissey, SC, said his client blacked out.
"What you could find is that the evidence proves to absolute certainty that it did happen," he said.
His sisters sat in shock in the court and watched as he was taken to the cells.
Farquharson will be sentenced at a later date.
