THE school communities of St Marys and Colyton rallied together on Friday to pledge their stand against child sex abuse.
Four hundred balloons were tied to Bennett Road Public School's fence to mark White Balloon Day, which coincided with Child Protection Week.
Representatives from St Marys South, St Marys, Oxley Park and Colyton public schools, along with Colyton and St Marys Senior high schools, teamed up with Bennett Road for the cause.
Lindsay MP David Bradbury, state Mulgoa MP Tanya Davies, Penrith councillor Prue Car and several Penrith Panthers rugby league players attended the launch to show their support and spread the message.
Proceeds raised from a treasure hunt will go to Rosie's Place for its support of child sex abuse victims and their families.
"The message to the kids is that there is help out there and people are willing to listen, no matter what the situation," Bennett Road principal Matthew Plummer said.
"In many cases, teachers are the first to find out about these cases."
He said the seriousness of the cause wasn't lost on children.
"Kids can't be underestimated," Mr Plummer said.
"They're smart and understand when something wrong happens. They tend to look out for one another."
"This is the third year Bennett Road Public School has commemorated White Balloon Day.
A parent approached the school two years ago after his daughter was sexually assaulted six times by a
relative who was later jailed.
