BONDI JUNCTION ATTACK: Eight people remain in hospital after being stabbed by Joel Cauchi in Westfield

Flags around the country fly at half mast as Australia wakes to a national day of mourning after the horrific attack on shoppers at Bondi Junction Westfield at the weekend.

Six people have died and 12 were hospitalised, including a nine-month-old baby, after Queensland man Joel Cauchi went on a stabbing rampage at the busy shopping centre on Saturday afternoon.

NSW Health confirmed on Monday morning that eight people, including the baby girl whose mother Ashlee Good died in the attack, are in stable conditions in hospitals around Sydney.

A male and female are in a stable condition at the intensive care unit at St Vincent’s Hospital.

A female remains in intensive care at Royal Prince Alfred Hospital, while a male is stable in a ward.

Two female victims are in stable conditions at Prince of Wales and St George Hospital.

And a fifth female victim is in a serious but stable condition in intensive care at Royal North Shore Hospital.

The nine-month-old baby girl, Harriet, whose mother Ashlee Good was murdered in the massacre, underwent surgery over the weekend and is in a serious but stable condition after being stabbed several times in her pram by Cauchi.

“NSW Health extends its deepest sympathies to the families, friends and loved ones of those who died and were injured at Bondi Junction Westfield,” a department spokesperson said.

NSW Premier Chris Minns announced a national day of mourning as he appeared on breakfast television and radio programs on Monday morning.

Mr Minns sought to assure the community that authorities would leave “no stones unturned” in the police investigation and inquiries into the incident — including providing “extra resourcing” and funds to the NSW coroner for their inquiry — to ensure history does not repeat.

“We know the public wants information about this terrible, terrible, violent incident and we’re determined to get as much information as we possibly can,” he told Sunrise.

“We know that this inquiry needs to look at police resourcing, as well as keeping the community safe. It’s going to be a difficult task and there’s no easy answers, but obviously that will be the focus of all police inquiries and any government action in the weeks ahead.”

Overnight, NSW Police have closed the crime scene at the Bondi Junction shopping centre and handed the property back to Westfield to consider when to reopen.

NSW Police Commissioner Karen Webb confirmed police were working with Westfield on when shops may return to business. As of Monday morning, its doors remain closed.

“It will take some time to prepare the stores for reopening,” Ms Webb told ABC News Breakfast.

“No doubt there’s some work to be done with stakeholders inside the Westfield in terms of their trauma to what has happened. So that will be done very carefully, no doubt.”

She said police had seized “many exhibits” from the crime scene and will begin the “very slow, methodical process” of interviewing witnesses, the assailant’s family, and combing through evidence.

“Overnight, 50 additional witnesses have come forward with information. We’re still calling for witnesses. If people haven’t yet spoken to police… we ask them to call Crime Stoppers,” Ms Webb added.

Meanwhile, from Monday, customers and centre staff can collect their vehicles that they had to abandon at the Westfield car parks after the attack.

Large crowds of people queued at the centre overnight as they waited to access their cars from 6am on Monday.

Scentre Group, the parent company of the shopping centre, said it was working with NSW police for customers to regain any personal belongings left behind in the chaos.

On Saturday afternoon, Scentre Group CEO Elliott Rusanow extended the “deepest an most heartfelt condolences to the families and loved ones of those impacted by [the] tragedy at Westfield Bondi.”

“We extend our deep appreciation for the swift and brave action of our team and first responders,” Mr Rusanow said in a statement.
