National child protection and awareness organisation Bravehearts celebrated educating 200,000 children about abuse in Australia with this week's performance.

The not-for-profit organisation's acclaimed personal safety program, Ditto's Keep Safe Adventure, was performed for the children by Braveheart representatives and Ditto the Braveheart lion.

A symbolic and celebratory cake was cut by Braveheart representatives and Bowral Primary School staff.

Year 3 student and SRC member Ava Lambie said she really enjoyed the performance and Ditto was her favourite part.

"I thought it was a very good show teaching kids about safety and I learnt it's okay to say no, and run and tell someone you can trust," Ava said.

Assistant principal for early stage one Virginia Pridham said "it was an entertaining and fun show, it gets the message across and it's effective."

"The Bravehearts show covers the safe living component of the PD Health PE syllabus in a sensitive and well executed way," Ms Pridham said.

The program teaches personal safety skills and underpins children's instinctive understandings and feelings around their personal safety in a way that is non-confrontational, safe and highly effective."

Bravehearts founder and executive director Hetty Johnston said Ditto has potentially saved 20,000 children from the horror of sexual assault.

Ms Johnston said aside from the devastating mental and social costs associated with child sexual assault, there is also a financial burden, with a financial cost to society of around $160,000 every time a child becomes a victim.

In this case Ditto and Bravehearts have saved taxpayers about $3.2 million," she said.
