A Thai fruit picker asked his ex-girlfriend if she wanted to die with him before stabbing her three times in the chest and then using the knife repeatedly on himself, a Victorian court has heard.
Charan Hannarong has admitted to the attempted murder of the 28-year-old mother-of-three Pentarkarn Yoosuan at a party in Wangaratta in November 2015.
The 40-year-old stabbed Ms Yoosuan with a steak knife and she needed multiple operations to survive.
On Friday, the Supreme Court heard Hannarong reached a state of "despair" when she rejected his attempt at reconciliation.
Hannarong and the young woman had met as fruit pickers on a farm in the state's north-east, started dating and then moved in together, prosecutor Daryl Brown told the court.
Both were in Australia to work and to send money back to their families in Thailand.
A few weeks before the knife attack, Hannarong punched Ms Yoosuan at a party, so they broke up and she moved out, Mr Brown said.
After repeated attempts to reconcile with her, Hannarong turned up at another party and asked again if they could get back together, to which she replied there was no chance.
At this point, he said: "Do you want to die? Maybe we can die together?"
Ms Yoosuan thought he was joking but then became concerned for her safety.
While she went away to talk to a friend, Hannarong went to his car and got a steak knife.
He came back to the party and stabbed her in the chest three times, before stabbing himself 25 times.
"It just seems to be an outburst of violence because of her refusal to come back to him," Justice Christopher Beale said.
Hannarong's self-harm would not be a mitigating factor in his sentence, the judge said.
Ms Yoosuan had to be flown to Melbourne for multiple operations for her serious injuries.
At the time of his offence, Hannarong had overstayed his visa and was living in Australia illegally, the court heard.
He will be deported after doing jail time.
His lawyer James Fitzgerald said his client was in a distressed state and slightly under the influence of cask wine he'd been drinking at the party.
He is now very remorseful and grateful Ms Yoosuan survived, Mr Fitzgerald said.
Hannarong will be sentenced on May 17.
