Dawn Singleton, the daughter of adman John Singleton, is one of the victims of the Bondi Junction killings.
The 25-year-old was one of six stabbed to death in the Westfield shopping centre.
Twelve others suffered stab wounds before the attacker was shot by a police officer.
Dawn Singleton, who attended Kambala school in Sydney's Rose Bay and then gained a bachelor of communications at the University of Technology Sydney, worked at White Fox Boutique as an ecommerce assistant.
The business paid tribute to her.
"Over the weekend we lost not only an employee of White Fox but someone special to us who felt like a family member," White Fox Boutique said.
"We are all truly devasted by this loss.
"Dawn was a sweet kind hearted person who had her whole life ahead of her. She was really amazing."
Kambala School paid tribute.
“We extend our sincere condolences to her family and acknowledge that the loss of a family member from such a random act must be exceptionally hard to comprehend,” said principal Jane Danvers,
“There is no doubt the ramifications from this incident may continue to unfold over the coming days and weeks with many of our community potentially affected.”
