Westfield Bondi Junction attack: Security guard injured during deadly rampage recalls the moment his colleague was stabbed to death as harrowing new vision emerges

A Westfield security guard injured in the Bondi Junction terrifying rampage says he'll never forget helplessly watching as his colleague was stabbed to death by a crazed knifeman.

Five women and security guard Faraz Tahir were stabbed to death as Joel Cauchi attacked innocent bystanders in a frenzied attack last Saturday.

Security guard Muhammad Taha is still recovering in hospital after he was stabbed in the stomach during the attack.

He recalled the moment he and his new colleague Mr Tahir came face to to face with Cauchi, as new vision emerged of the pair moments before they were attacked.

The pair had been sharing stories about their families back in their homeland of Pakistan moments before the chaos. 

The footage filmed by a shopper shows the security guards walking through Westfield before being alerted by screams as a male onlooker frantically pointed them in the direction of Cauchi, who had already started his rampage.

A woman was heard calling for an ambulance while bystanders were seen in the background helping injured victims.

The security guards moved off-camera as they headed towards an injured woman lying on the ground  when they were spotted by Cauchi.

'He all of a sudden noticed us, he jumped on Faraz and he stabbed him in the chest,' he told Nine News from his hospital bed.

'When Faraz turned (around), there was blood all over his chest, I was very shocked.

'At the same time, he jumped over to me.

'I tried to defend myself, I tried to use my hands and somehow he managed to stab me in the stomach.'

Mr Taha initially didn't notice he had been wounded and  with the only concern for his colleague who was on his first day on the job.

'I was just looking after Faraz. I tried to help him,' he said.

Mr Taha called his best friend, Muhammad Fahad, who also works as a security guard in the shopping centre, who rushed to his colleagues' aid.

'He did everything in his capacity (to help), he helped me, other people and Faraz, so I'm very grateful for him,' Mr Taha said.

' There was lots of blood. He put pressure on my side. Because of him, I survived.

'Without him, I wouldn't be here.'

He had no idea that Mr Tahir had died until two days after the stabbing.

I could have been the one (that died). There was (a) very mixed feeling, I (can't) even express it, I was speechless at that moment

Mr Taha also thanked Prime Minister Anthony Albanese and NSW Premier Chris Minns for approving his permanent residency in Australia.

The Prime Minister said people like Mr Taha were welcome in Australia.'

'This is again another person who is newly arrived, was here working, and put his life on the line in order to protect Australians who he didn't know,' Mr Albanese said on Thursday night.

'Amidst all this carnage and sorrow, there are stories of bravery ... he certainly is the sort of character that we want to see continuing to contribute here in Australia.'

Mr Taha now wants the same citizenship recognition for his best mate who saved his life.

'I want that (same recognition) for Fahad, he deserves it,' Mr Taha said.

Westfield Bondi Junction reopened for trading on Friday, six days after the rampage. 

Around 30 stores remained closed. 

Thousands will flock to Bondi Beach this Sunday for a candlelight vigil for the six victims.

The vigil gets underway at 5.30pm.
