Linda Britton has been found guilty of killing her daughter and another woman after hitting them with her car during a violent street brawl three years ago.
Aboriginal and Torres Strait Islanders are advised this story contains the names of people who have died.
Britton, who had pleaded not guilty to manslaughter and dangerous driving, was in court when the jury returned after only 2 hours and 20 minutes of deliberations.
On the night of September 28, 2019, Britton's daughter Skye Luland and another woman Kazzandra Widders, were both killed when they were crushed under a vehicle driven by Britton at Nambucca Heads on the NSW Mid North Coast.
In his closing statement, Crown prosecutor Mr Campbell told the court that "unquestionably the night of September 28, 2019 was a night of unmitigated tragedy".
"It is perhaps hard to estimate the sense of loss over these two young women — one with very young children."
He then queried the jury about Britton's actions and decision-making.
"Did she have to drive an accelerating car at two women fighting on the ground to defend her daughter," he asked.
Mr Campbell called it an unreasonable response in "a charged and chaotic moment".
In the defence's closing statement, Scott Fraser described the then 52-year-old Britton as a woman with multiple injuries facing younger attackers.
He told the court Britton made the decision to drive the car in the direction of the two women because she believed her daughter was being bashed to death.
"To leave the scene as she perceived it was to leave her daughter to die," he said.
Evidence before the court included photographs of boondi, or fighting sticks, taken from the scene.
The court also heard that key witnesses from Ms Widders' family were allowed to leave on the evening and no personal searches, car searches or DNA were collected at the time.
Sentencing options
After the verdict was returned today the Crown prosecutor sought a detention application.
In response, Judge Sarah Huggett considered whether the sentence will be served by a full-term imprisonment.
Defence counsel Mr Fraser submitted that full-term imprisonment was not the only option.
Judge Huggett told the court, "I do not consider that I am able to be satisfied that the offender will be sentenced to imprisonment to be served by full-time detention."
Britton is not in custody currently and her bail continues with increased reporting requirements.
Mr Fraser sought a sentence date later than six weeks to allow time to provide the court with a psychological report.
The date for sentencing is set for February 2023.
