When Senior Constable Danny Kidd first joined the New South Wales police force, he saw countless families living with violence.
"Looking at my local area in particular there's a lot of young people who aren't aware what healthy relationships are."
He wanted to see that change.
So Senior Constable Kidd set up the Kids Say No program to promote healthy relationships to children.
The program teaches everything from how to recognise signs of abuse, to forming positive family relationships.
"It's important for the police to drive it, to show that we say no to violence. And then we hope, which the boys have done, they will follow."
At least 40 students have already taken part in the eight-week program.
Participant 16 year old Luca Angrisano from Canterbury Boys' High School, says he is excited to use the skills he's learned from the Kids Say No Program.
"I went home and spoke about this with my parents and I said what I've learned today. And around the kids at school I explained about the different types of violence and what we're doing in the program. It's affected us every single week and it will affect us for the rest of our life."
Canterbury Boy's High School Principal Belinda Giudice says she has already seen dramatic changes in the way her students view relationships.
"It's enabled our kids to understand the skills for healthy relationship and to stand up for this very important issue and to stand up within the community."
This program is the first of its kind to be run by New South Wales Police, and Senior Constable Kidd says there are now plans to expand it across the state.
"Today's society is all about the young people who are the ones who grow up to educate the younger ones again. So getting out there for the younger generation is definitely a positive because they can stop it before it gets any worse."
