Brophy's Anna Sanderson and Delise Oldfield rolled out a social and emotional coaching program at Warrnambool secondary schools last year. Ms Sanderson said 26 students took part in the eight week program and identified bullying as an issue that needs to be addressed.

"Those 26 students took their ideas back to their respective schools and have worked with their school leadership and well-being teams to plan each school's contribution to the day of action," she said.

Students will take part in a range of activities on Friday, which is the National Day of Action Against Bullying and Violence, including a march and creating a message against bullying on a school oval.

The project was a partnership with Melbourne University's Centre for Positive Psychology and the Alcohol Drug Foundation.
