I'm raising 2 children with my wife in Nundah and we have plenty of friends with kids living in the suburb. Our kids are just as safe here as any other suburb nearby. Unfortunately times have changed over the years, but so do the demographics of areas. Nundah is very family orientated nowadays. You should check out the Nundah Village Festival on the second Sunday in September to see just how family/kid friendly Nundah can be.
