A mother who was stabbed to death in the Sydney shopping centre knife attack has been pictured for the first time.

Ash Good, 38, was among the six shoppers fatally knifed in the city’s Bondi Junction Westfield at around 3.20pm on Saturday.

The attacker, a 40-year-old man, was shot dead by a female police officer outside a discount shop in the mall.

Ms Good was named as one of the victims of the attack by several local media outlets.

Hours before the attack, she had posted a video on Instagram of her nine-month-old baby smiling in a car seat.

The attacker is said to have stabbed the baby and then Ms Good, according to The West Australia.

Ms Good then ran to two brothers in a shop and begged them to take her baby, the newspaper reported.

The men used clothes to attempt to stem the bleeding on both Ms Good and her daughter, but the mother’s injuries were too severe.

Ms Good died in St Vincent’s Hospital on Saturday night, according to local media.

The baby remains in Sydney Children’s Hospital and is being treated for multiple stab wounds to her abdomen.

A friend of Ms Good told News.au that she was a “beautiful human” and “the world’s best mum”.

Police Commissioner Karen Webb said the motive of the attacker is unknown, but terrorism is not suspected.

“Things are very raw at this stage,” assistant commissioner Anthony Cooke said in a press conference. “I do not have many details... it is a very big crime scene. This is about dealing with this terrible situation and making sure everybody is safe.”

Bondi Junction is a large shopping centre, comparable with the Westfield in Stratford in London, and Saturday afternoon is one of its busiest times.

One eyewitness told ABC News: "He just started floating towards us and all I heard was 'put it down' and then she shot him.

"But we were in no doubt, if she didn't shoot him, he would have kept going. He was on the rampage.

"Then she walked over and gave him CPR. He had a big blade on him - she chucked the knife away.

"He looked like he was on a killing spree."

Several posts on social media showed crowds fleeing the mall and police cars and emergency services rushing to the scene.
