HORSHAM West Primary School students have joined a national campaign to stamp out bullying.
Hanna Poswiat, 11, with her friend Katie Pohlner, 12, called on their peers to dress in blue on Friday.
The day recognised Queensland girl Amy "Dolly" Everett, then 14, who took her own life last year after being bullied.
Her parents Kate and Tick Everett want Dolly's death to not be in vain and started a foundation, Dolly's Dream.
Their work to raise awareness about cyberbullying led to the launch of the inaugural Do It For Dolly Day on Friday, which saw schools and workplaces across Australia "go blue" - Dolly's favourite colour - in a bid to educate communities and empower them to stamp out bullying.
She had endured persistent bullying and abuse at her school and had just finished a drawing, captioned "speak even if your voice shakes" before her death.
Hanna, a year six student, said her mother learned about the day on social media and motivated her to do something at her own school to recognise Dolly.
"We chose the colour blue because it was Dolly's favourite colour," Hanna said.
Hanna and Katie said they had experienced bullying and said there were many like them - but many were afraid to speak.
"There are a lot of people and peers who judge others and say hateful things. They do not understand what the other person is going through," Katie said.
The school's acting assistant principal Karen Gebert said the school was proud of Hanna's initiative and wanted to support her passion.
"I am incredibly proud of Hanna because she has brought this cause to our attention and felt strongly enough about it that we should recognise Dolly and bullying; and the fact that she has taken a stance and raising awareness about the issue," she said. "The number of student wearing blue speaks for itself. It shows that the parents and community support the cause."
