NSW Police Inspector Amy Scott, who was praised for bringing the Westfield Bondi Junction stabbing attack to an end, has been diagnosed with a rare and aggressive form of breast cancer.

Police Legacy NSW, the NSW Police Force's charity, said their "beautiful friend and colleague" was selfless and compassionate, and needed "the strength, compassion, and support of her community".

"Just as she is so much more than her diagnosis, she is so much more than 'the hero of Bondi Junction,'" the organisation said.

"She is a loving wife, mother of two young boys, devoted to serving the community through her work as a NSW Police Officer, and widely known as selfless, compassionate, and kind."

The charity has set up a fundraiser to "ease the financial burden" for Inspector Scott and her family.

"She is fiercely independent and the first to champion others. Whilst she is being well supported by her family, friends and colleagues, Amy has a long uphill battle ahead to beat this insidious disease," Police Legacy NSW said.

NSW Police Minister Yasmin Catley said "the whole police family are suffering at the moment with the knowledge of her diagnosis".

Police Commissioner Mal Lanyon said Inspector Scott and her family had been "dealing with this diagnosis for some months now" and said she was "surrounded by the unwavering love and support" of the entire force.

"Despite everything Amy is facing, she continues to show the remarkable person that she is by going out of her way to support her workmates, regularly coming into the station to offer comfort and assistance to those impacted by the recent Bondi terror attack," he said.

"Amy has requested privacy at this time."

Scott an 'absolute champion'

Inspector Scott was labelled a hero and credited with saving lives after she pursued Joel Cauchi through Bondi Junction Westfield after a stabbing rampage in April 2024, which ended in the deaths of six people.

She was subsequently recognised with the Commissioner's Valour Award.
