‘Look after each other’

“It’s just so horrifying to think that people could get to this point right in our community.”
Ms Chaney described the Mosman Park community as “small and tight-knit” and said she hoped the people would wrap their arms around each other.
“We just have to hug our kids and, you know, reach out for support if you need it, and look after each other.”
