It was initially thought her injuries were much worse but she was now "doing okay".
She said the attack had traumatised the victim.
A woman in the security office at the mall refused to comment.
Centre manager Jonathan Douglas said he had been notified of the incident.
He confirmed the woman was an employee of Max, a clothing store in Sylvia Park.
"Our thoughts and concerns go out to the victim."
"We are hopeful that through the CCTV footage picked up of the incident and given to the police that the police will quickly find the culprits. This appears a completely random act of violence on an employee of Max and as mentioned our thoughts are with her and her family at this time."
Mr Douglas said security patrols at the mall's carpark areas had been increased.
The Max store manager was obviously upset about the incident. "We don't want to talk about it."
She said the staff member's privacy prevented her commenting.
