Yixuan Cheng, 25, was from China and was studying for a master's degree in economics at the University of Sydney, according to Sky News Australia.

Her name was confirmed by Australian prime minister Anthony Albanese.

Ms Cheng's fiance in China, named as Mr Wang, told a Chinese publication he had spoken to her on social media moments before the attack on Saturday.

"She even tried on clothes for me to see," he said, adding that she had sent him a photo of her trying on a handbag earlier that afternoon.

After the stabbing attack, he tried to contact her but there was no response.

It comes as New South Wales police revealed they are looking into the possibility that attacker Joel Cauchi targeted women when choosing his victims in the Westfield shopping centre in Bondi Junction.

The attack was brought to a stop when lone police officer Amy Scott shot and killed Cauchi.

Police have said that the 40-year-old had a history of mental health issues, and they do not believe the attack was terror-motivated.

Ashlee Good

Ashlee Good, 38, a new mum, tried to save her nine-month-old baby Harriet when she was attacked.

She was said to have passed her baby off to two men after she was badly injured.

In a statement, ABC reported her family said: "Today we are reeling from the terrible loss of Ashlee, a beautiful mother, daughter, sister, partner, friend, all-round outstanding human, and so much more.

"We appreciate the well wishes and thoughts of members of the Australian public who have expressed an outpouring of love for Ashlee and our baby girl."

The family added that after "hours of surgery" baby Harriet was doing well and they offered their thanks to the men who cared for her during the attack.

In one of her most recent posts, Ms Good wrote on her LinkedIn page: "And just like that, seven beautiful months have passed and it's time to return to the office.

"It's not lost on me what a privilege it is to become a parent.

"And then to be gifted some extra time away from work to spend with your child... it's very special."

They said: "With heavy hearts, we share the news of a tragic incident at a Sydney mall, where lives were lost, including a courageous Pakistani national Faraz Ahmed who had moved from Brisbane for work."

The Ahmadiyya Muslim Community Australia said: "Faraz Tahir, aged 30, sought refuge in Australia just a year ago, fleeing persecution in his home country of Pakistan. He quickly became an integral part of our community, known for his unwavering dedication and kindness."
