A day before she was allegedly murdered by her "controlling and abusive" fiance, Canadian hairdresser Lisa Harnum called her mother in distress, asking "mummy, please come and get me," a court has heard.
But Ms Harnum's fiance, Simon Gittany, allegedly discovered her plan to escape from the relationship and stopped it in its tracks.
Later that night, the young woman allegedly rang her mother back and said "mummy, remember that I love you ... if anything happens to me, call Michelle [her counsellor]."
The recollections came from Ms Harnum's mother, Joan, as she gave evidence in Mr Gittany's murder trial in the NSW Supreme Court on Tuesday.
Mr Gittany, 40, is accused of grabbing Ms Harnum on July 30, 2011, as she tried to run from their unit beside Hyde Park in the Sydney CBD, picking her up and dropping her from their 15th-floor balcony.
Mrs Harnum broke down in the witness stand as she spoke of a series of phone calls and text message exchanges with her daughter on the day before her death.
"She called me and said 'mummy, please come and get me," Mrs Harnum said of her daughter's request to come to Sydney from Canada.
"I said, 'how urgent is it? I can come down on August 6."'
The court heard that Mrs Harnum booked her flight, and her daughter then booked a one-way ticket back to Canada.
But Mr Gittany allegedly found out about the plan and became incensed.
"She called me back and said that Simon had found out she was trying to book my flight to come down," Mrs Harnum said.
"He had found the information online that she had tried to book the flights. She found some files on the computer which showed that he had been tracking her flights and her emails. She was very upset.
"She just wanted to get out. She said that she was going to try and find a way to leave."
Later that night, Ms Harnum called her mother back.
"She said, 'mummy, if anything happens to me, please contact Michelle', her counsellor, and she made me take down the details.
"She was in the bathroom making the phone call and she said she was going to contact me as soon as she could the next morning."
A day later, a Canadian policeman arrived at Mrs Harnum's home to inform her that her daughter was dead.
Mr Gittany denies murdering Ms Harnum.
His barrister, Phillip Strickland, SC, asserts that the pair had a troubled but ultimately loving relationship.
Mr Strickland told the court on Monday that Ms Harnum had a "vulnerable personality" and had previously engaged in risk-taking and destructive behaviour, such as running through busy traffic on George Street in the Sydney CBD, and on one occasion, jumping from a moving car.
He said the 30-year-old may have climbed over the balcony with the intention of committing suicide or as a cry for help. She had then slipped and fallen to her death, before Mr Gittany could save her.
The trial continues.
