Coral Avenue and Govan street are great quiet street with their own community groups. Kids all playing together and street drinks/catch ups regularly
West footscray is a safe area. The safety of your young family will not depend on the street you live on within this small pocket of melbourne. If you're afraid of Footscray choose somewhere else to live. West footscray is a very welcoming, diverse suburb full of lots of young families. I don't share your perception at all and I would never choose to live in a suburb I believed was unsafe.
