"She was just there with other people around her. People were just walking past ignoring her.
"I just felt bad. I don't like judging people. There's a lot behind people that no one ever knows. I feel sorry for people like that."
He said he asked the group with Jess what they were doing, then asked Jess what had happened.
"She told her story. I took her to the ATM and said, 'Here's your money to go home, enjoy your life.'"
A volunteer worker for the homeless who filmed the incident and uploaded it to Facebook, Siham Carollisen, 30, said she and her brother Mirwan had seen Jess and her partner on the streets since they started taking out meals to the homeless in May.
She said Jess's partner was an Australian but was evicted when he fell behind with his rent and was then blacklisted by other landlords. Jess told her that the couple, aged in their mid-twenties, had lived on the streets ever since.
"She said about 18 months," Carollisen said. "She's had a rough road."
She said that when Roose first approached her she took offence.
"He said to her: 'Why are you here? Who are these people, are they Jesus people?'
"We said, 'We are not Jesus people.' She started telling him off, saying, 'It's arrogant people like you who make it harder for these guys to do what they do. The city is falling apart.'
"She had lost four friends on the street in the last month to drug addiction.
"She was getting really upset saying people judge those who are begging on the street. 'No one is perfect. Don't judge.'
"As soon as he [heard] that, he held his hand out to her and said, 'Come with me, I'm going to sort you out.' I followed them to the ATM, that's where the video came about.
"He disappeared into the night. We walked her back. She was so emotional, she was just so overwhelmed."
The Herald contacted a Facebook friend of Jess who said he spoke to her tonight but she did not want to talk to the Herald unless she was paid for it.
Roose declined to say how much cash he gave Jess, and it is not known whether she is still in Perth or on her way home.
