2 million kids to stand up against bullies

Almost two million students will take part in a national day against bullying, nearly double last year's participation rate.

Prime Minister Malcolm Turnbull has released a video message to mark the highest participation levels in the history of the National Day of Action Against Bullying and Violence.

"The overwhelming response to this year's National Day of Action highlights that Australia's schools, students and families are united in stamping out bullying," Mr Turnbull said on Friday.
