A woman on trial for murdering her mother expressed remorse for the killing and told a psychologist she wished she was dead instead, a court has been told.
Gabrielle Woutersz, 25, is accused of striking Norma Cheryl Woutersz, 56, to death with a hammer at their Dunlop home in October 2014.
It's alleged she killed her mother before trying to bury her body in a garden bed in the backyard.
Woutersz was arrested after her father arrived home to find his wife dead, suffering significant head injuries, and the defendant cooking eggs in the kitchen.
Woutersz pleaded not guilty to murder and her month-long ACT Supreme Court jury trial has now entered its third week.
The killing is not in dispute.
Prosecutors argue Woutersz's extensive past use of drugs contributed to her mental state at the time of the killing, while Woutersz's defence is arguing she suffered a mental illness and didn't know what she was doing was wrong.
Jurors heard on Monday evidence from psychologist Thabile Twala, who assessed Woutersz in November 2014.
In a mental state examination, Ms Twala had noted Woutersz seemed hopeless and expressed "profound guilt and remorse over her incarceration and her mother's death".
She said Woutersz had told her she wished she was dead instead of her mother, but didn't want to put her family through additional pain.
The defendant had told the psychologist, who noted Woutersz appeared remorseful and distressed, that she'd "messed up" her father's life.
She'd also told her: "I feel lonely without the voices. They did not do anything wrong."
The court heard the defendant's father had later come around to visiting her and she had been "surprised by the warm reception her father displayed".
"Her father told her the whole family love and care about her," Ms Twala said.
The trial, before Chief Justice Helen Murrell, continues.
