The sixth person killed in the Sydney mall stabbing attack has been named as 25-year-old Yixuan Cheng.

According to 9 News, she was a Chinese national studying in Australia. 

"Unfortunately, she doesn't have any family here in Australia," Nine News reporter Sarah Stewart said.

"Police spent the day yesterday trying to contact her family back home in China. She was simply at [Bondi Junction] Westfield on Saturday shopping like everybody else."

It's understood she was doing a master's degree in economics at the University of Sydney.

The day of the attack, Cheng had finished exams and went to the mall to try on clothes, news.com.au reported. 

The news outlet, quoting her fiance Mr Wang in Chinese media, detailed one of her final conversations.

"She happily talked to me on the phone at around 3 in the afternoon. She even tried on clothes for me to see," Mr Wang said.

"Unexpectedly, after hanging up the phone, a stabbing incident occurred."

He couldn't get in touch after hearing about the rampage at Bondi Junction Westfield.

"I contacted her day and night, but there was no response at all. The whole family was so anxious that they didn't dare to think too much."

The attacker, 40-year-old Joel Cauchi, was shot dead by police in the mall after he lunged at an officer with his knife.

The other victims killed in the attack were 55-year-old artist Pikria Darchia, architect and mother-of-two Jade Young, security guard Faraz Tahir, 25-year-old daughter of a millionaire Australian businessman Dawn Singleton and 38-year-old first-time Ashlee Good, whose nine-month-old baby girl was also wounded in the attack. 

Seventeen people were hurt in the attack, of which 14 were women.

Police are investigating if women were targeted in the rampage.
