Prime Minister Malcolm Turnbull has written to every school principal across the country urging them to take a united stand against bullying.

The federal government is this morning announcing an extra $1.37 million over the next three years to fund the National Day of Action against Bullying and Violence (NDA) and is encouraging all schools to take part.

"We believe all students have the right to be safe at school. Bullying and violence has no place in Australia," Mr Turnbull wrote in the letter.

"This is our chance to stand together. Together we can reduce the incidence of bullying, whether inside the school gate or online, and eliminate it wherever we can."

Education minister Simon Birmingham said while there is no "silver bullet" to tackling the issue, discussions should be acknowledged and encouraged.

"They need to happen across the entire school community - between principals and teachers, parents and studnets," Mr Birmingham said.

"Everybody has a role to play."

The prime minister was deeply affected by the death of teenager Dolly Everett earlier this year and since focused on bullying in schools and youth mental health.

The 14-year-old, who was the face of Akubra hats, took her own life after months of bullying, with her death garnering worldwide attention.

“The Prime Minister, along with all Australians, was profoundly affected by the death of Dolly Everett and follows recent commitments at COAG to address bullying both inside the school gate and online,” Mr Turnbull said in a statement.

“The NDA is the key anti-bullying event in schools and in 2018 schools are being asked to imaging a world free from bullying and share their big ideas to make this a reality," he said.

More than 2300 schools have already registered for the national day on March 16 and will have access to resources and lesson plans as well as a support website for students.

The prime minister said some groups are holding student conferences while others are planning pledge walls to 'make their school free from bullying'.

It comes amid concerning levels of home-schooling, with parents of up to 2,500 students citing bullying as the main reason they are pulling their children out of Queensland schools.
