A Sydney family will be nominated for a bravery award after they risked their own lives to save a man attacked by an alleged terrorist.
Chilling video shows residents arming themselves after 22-year-old Ihsas Khan's frenzied stabbing attack - and they were fearless in the face of terror.
The residents used fence palings and rocks in an attempt to smash Khan's weapon from his hand.
"The bravery I can't even imagine, but I can assure you if it were the other way around, Dad would do the same for any one of them," Lisa Ballard said.
Ballard's father is Wayne Greenhalgh, who fell victim to the random and hysterical stabbing.
"Someone's run around, yelling 'Allahu Akbar, this is a good day to die'," a witness said.
Khan allegedly tried to slash the 59-year-old grandfather's throat, before cutting his chest and slicing his fingers.
He went running into a hair salon begging for help.
"He came in with all of his body covered in blood and he called me, 'Help, help, help!'" a witness said. "I was so shocked I didn't know what to do."
Customers tried to keep critically wounded Greenhalgh alive.
Outside, Khan tried to force his way into the salon - but residents put up a fight until help arrived.
"He's thrown it and it's hit him straight in the middle of the head. It stunned him and that put him back enough to allow Wayne to get into the shop," another witness explained.
The attack came a week after IS called for lone wolf attacks on everyday Australians. Wayne Greenhalgh's described as a 'true blue Aussie' - and police say that's why he was targeted.
Neighbours say they watched Khan transform over the past few years, preaching Qur'anic verses and trying to convert neighbours to Islam.
Khan's friend believes he suffers from a mental illness.
"Obviously he's tormented mentally because [his] family [is] broken up and [his] mum died. He needed some assistance - he needs some help."
Khan's been charged with committing an act of terror and will appear in court on Wednesday.
