The police officer who single-handedly stopped Joel Cauchi's murderous stabbing spree at Westfield Bondi Junction has been diagnosed with a rare and aggressive form of breast cancer.

NSW Police Inspector Amy Scott ran to the fifth level of the Sydney shopping centre in 2024 after being alerted to the terrifying rampage. 

She confronted Cauchi and fatally shot him in the chest when he refused to drop the knife.

A fundraiser has been set up to help Inspector Scott and her family during her battle with the disease by NSW Police Legacy.

'Our beautiful friend and colleague, Inspector Amy Scott, has recently been diagnosed with a rare and aggressive form of breast cancer,' the fundraiser said.

'Beyond her dedicated service to the community, Amy is a devoted wife, a loving mother of two young boys, and has a family who depend on her and walk this journey beside her every day.

'She is every bit the remarkable human you would think. 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.

'Amy now needs the strength, compassion, and support of her community. This is a powerful reminder that even our strongest people are human, and this fundraiser has been created to ease the financial burden for Amy and her family during this incredibly challenging time.'

NSW Premier Chris Minns said he was devastated by the news.

'I spoke to Amy a couple of weeks ago. I mean, she's a genuine, bonafide Australian hero, someone that we have got we owe a huge debt of gratitude to, not just because of her heroic actions in Bondi Junction of a couple of years ago, but also she's been an inspiration to the exact same officers that attended the terrorism event on the 14th of December,' he said. 

'She's so important for New South Wales Police and our community. If anyone deserves a break, it's Amy, and we just wish her the very best. She's an absolute champion.'

Following her act of heroism, Insp Scott said that she was just one example of 'ordinary people called to do an extraordinary thing'.

'It was quite a traumatic day for everybody involved,' Insp Scott told a graduating class of police officers.

'I wasn't the only person there and that's why I have stayed quiet and probably will continue to stay quiet because there are really important people that responded that day that have been impacted.'
