More than 200 homes were lost in the bushfires that ravaged NSW last week.

On Wednesday, the school of around 110 students held a hot dog day and raised more than $400 for those affected by the devastating fires.

Teacher Sonya Salvestro said she was proud of the students for being so willing to help others.

"My neighbours from when I lived in the Blue Mountains some years ago lost their home to the fire at Winmalee," Ms Salvestro said.

"Our principal Justin Dawson thought it was a great idea to do something to help.

"I think it is a good lesson for students to think about others in need.

"Imagine coming home to find you have lost everything. It would be devastating.

"We had the floods here, so to some degree the students are aware of loss and how hard it can be.

"We had some discussions with older students about the fires and they were all very keen to do something to help."

The funds they raised from the sale of hot dogs, drinks and fairy floss will be donated to the Red Cross.
