Footage shot in a police interview room of a woman caked in dried blood as she discussed decapitating her mother won't be published, a court has ruled.
Jessica Camilleri, 27, was last week found guilty of manslaughter over Rita Camilleri's July 2019 stabbing death.
The jury accepted she had a partial defence to murder due to a loss of control caused by her mental conditions that include autism spectrum disorder and an intellectual disability.
Those mental conditions also provided some reason for trial judge Helen Wilson to order on Monday that the police interview footage not be released.
The interview, played during the trial, was shot hours after Camilleri had been stopped by police on her neighbour's front yard but before evidence from her body was able to be collected.
As a result, the footage depicts her in a blue dress covered in her mother's blood, with dried blood splattered on her face and police evidence paper bags on her hands.
Justice Wilson said the public had an interest in being able to access material tendered in the trial so it could perform its function of overseeing the justice system.
But, given the transcripts of the interview were available for release, the interest in seeing the footage was outweighed by the public's interest in protecting a vulnerable person.
It was possible another inmate could see the footage, take a negative view of Camilleri and physically target her, the judge said.
"It is not unknown for such things to happen," Justice Wilson said, noting no actual claims of physical threat had been articulated.
A similar non-publication order had already been made for footage from a police officer's body-worn camera showing Camilleri at the scene of her mother's death.
Both applications were made by Camilleri's legal representatives and supported by the Crown.
Camilleri is expected to return to the NSW Supreme Court on February 17 for a sentence hearing.
