Simona Zafirovska, 22, denied she killed her mother Radica Zafirovska at their home in The Gap in 2016 and told police intruders had broken into the property.

Justice Ann Lyons said that was an elaborate ruse.

"You maintained that ruse in your triple-zero call when you pretended falsely that there were intruders in the house," she said.

"You then falsely caused a disturbance in the house to make it look as though there were intruders in the house.

"By the verdict it's clear the jury has not accepted that that was, in fact, the case."

A Supreme Court jury reached its unanimous verdict after a day of deliberations.

Zafirovska trembled as she stood in the dock while being sentenced to life in prison.

She will be eligible to apply for parole after serving a mandatory 20 years behind bars.

It was revealed on Wednesday that Zafirovska was adopted but did not know it until after she murdered her mother and DNA tests were taken.

Zafirovska shook her head after she was asked if she had anything to say to the court.

Prosecutor David Meredith described the killing as "brutal" and said it was not a spur-of-the-moment decision.

In sentencing Zafirovska, Justice Lyons said Radica, 54, was a loving mother who was generous to her daughter.

"She, by all accounts, was a wonderful person," Justice Lyons said.

"She was horribly, horribly injured."

Justice Lyons said Radica suffered severe blunt-force trauma, including multiple fractures to her face and skull.

Prosecutors alleged she used a piece of artificial wood to kill her mother as she slept in bed and that same plank was later found hidden in the daughter's bedroom.

The trial heard the university student made a triple-zero call about 7:00am that day, claiming intruders had broken in and attacked her mother.

But the prosecution contended that scenario was far-fetched because there were no signs of a break-in and intruders would have had to scale high fences without drawing the attention of neighbours or disturbing dogs.

While the lounge room and kitchen were ransacked, the prosecution argued it was contrived — as a gold chain and cash were left behind on a table.

It was the prosecution's case that Zafirovska staged the scene to shift the blame, Justice Lyons told the jury in her summing up.

The jury also heard the prosecution alleged Zafirovska stood to benefit financially if her mother died.

No blood found on daughter, defence says

But Justice Lyons said the defence counsel argued there was no evidence to support the suggestion she ransacked the house.

They also claimed hair found in Radica's hand was of potential significance but was not sent for DNA testing, Justice Lyons said.

She said the defence also told the jury Zafirovska's clothing was checked and that there was no blood found on her, including under her fingernails.

While the prosecution suggested she could have done away with the evidence by removing her clothes and washing herself, her defence counsel said sinks, drains and bins were inspected and nothing was found with blood on it, the court heard.

Justice Lyons said defence barrister Anthony Glynn QC argued the prosecution had not proven a reliable motive.

"Mr Glynn argues [it] may have been a vengeance killing over something that occurred in Macedonia," she said.

The court previously heard that in the month Radica was killed, Zafirovska enquired with travel agencies about booking a flight and told staff she was moving there.

Zafirovska's solicitor Neil Lawler confirmed they had lodged an appeal.
