Titled Paying it Forward the year 4 students wrote, directed, filmed and edited the three-minute film last year aimed at encouraging their schoolmates to extend a helping hand to others.

The kids became "kindness warriors" as they displayed examples of doing good deeds and then had their kind act returned to them at a later stage.

"I learned that it's good karma," said Elsie Furney-Goodwin. "If you do a good thing for someone, someone else will do something nice for you."

Eleven-year-old Sam Rorris explained that niceness breeds niceness.

"If someone does something nice for you it makes you feel like you want to do something nice for someone else," he said. "Being nice creates a chain reaction."

With messages such as: "Always show more kindness than you think is needed", and "When you are kind to others it not only changes you, it changes the world", the children of Mount St Thomas have taken their film to heart. Jagbir Bajwa understood the film was all about "paying it forward".

"One day your good deeds will come back to you in a good way," the 10-year-old said.

Of the 300 films entered from throughout the country, Paying it Forward was one of nine films nominated for Best Film by a School at the KidzFlicks Festival of Films by Children run by Bardic Studio.

The class will travel to Sydney on Monday night for a red carpet awards night when they will watch their film on a big screen.
