Bondi Rescue star Andy Reid helps provide first aid during Sydney mall stabbing attack

Andy Reid, a star lifesaver from popular show Bondi Rescue, used his lifesaving skills to help those injured in the Sydney stabbing rampage on Saturday.

Reid was in the Bondi Junction Westfield mall at the time of the attack and was among the heroes helping those wounded - but lost a long-time friend in the tragedy.

He told Newshub's Australia correspondent Emma Cropper how the incident unfolded.

"I was talking to the lady (in the store) about buying a bed in Myer and a guy came up to us and said 'everyone needs to evacuate, there's people being stabbed outside'," he said.

"We went to evacuate and as I went around the corner the shutters were already down in Myer so you couldn't actually get out into the area and I was like 'oh it's pretty serious'.

"As I looked through the holes in the shutter I heard two gunshots around the corner and I was like 'wow this is way more serious than I thought', and then I panned down and looked straight down towards a woman that was bleeding profusely on level four and I just thought 'I've got to get out there and help'."

 Reid described being "blown away" at how much blood there was when he got to the first victim.

"And then I saw another victim and then another victim about another 50 metres up and then there was one even further."

Reid was using clothing off hangers to try stop victims' bleeding out.

He also used his lifesaving skills, creatively using one victim's bra strap to hold gauze in place on a deep back wound.  

Reid said he then relieved police giving CPR on another victim so they could establish if there was another attacker. 

Joel Cauchi has been named as the sole attacker in the attack. He was shot dead by police in the mall after lunging at an officer.

Since the attack, there's been one thing on Reid's mind - losing one of his friends in the rampage.

Mum Ashlee Good died from her injuries in hospital on Saturday. She protected her nine-month-old baby girl, who was also wounded, from the killer then handed her over to strangers to be looked after.

"A lot of my focus is on a friend that was the mother of the baby - I've known Ash for probably eight to 10 years," Reid said.

"She's part of our run group. She was just a beautiful human that wanted to be a mum and she got that chance nine months ago and now it's completely been taken away from her.

"It's just a shit incident that didn't have to happen and it has… I can't stop thinking about her having to hand over her baby to a stranger knowing that she was in a bad way."

Reid said his actions that day didn't feel heroic for someone who has done "hundreds" of first aids as a lifeguard over the years.

He passed credit to those who came head-on with the attacker.

"It just felt like we were doing first aid, for me I think I wouldn't have wanted to come face-to-face with that guy and there was two people that definitely did."

A man with a chair as a weapon and the other using a bollard came head-on with the attacker, as well as the lone female police officer who eventually gunned him down.

Reid said for him they were the real heroes, alongside other authorities who put themselves in danger to help victims.

"To be honest, like, I can do first aid, I don't think I could take someone down with a big knife like that. Yeah, it's extremely brave from them."
