Collective Shout is a grassroots movement against the objectification of women and the sexualisation of girls.

"My main message is about teaching children to be resilient in a cultural environment that is often toxic to their welfare," Ms Tankard Reist said.

"I looked at the impact on children of hyper-sexualised images that they are bombarded with from the moment they are born, which gives them distorted ideas about their bodies, relationships and sexuality."

Ms Tankard Reist said parents at the workshop shared concerns around technology and pornography.

These included horror stories of their children being exposed - at time unwittingly - to extreme images of pornography.

While she acknowledges parents can at times feel helpless she advises them to keen channels of communication open with their children.

"Having healthy conversations with your child about their bodies and sexuality will help to protect them and they will know they can trust you," she said.

"You can't take a shame-based approach because then the child won't disclose what is really going on.

"Basic protections like internet filtering software and a family zone in the house can work, rules around screen time and so forth.

"We also need to model respectful relationships in the home and encourage children to have a broad range of interests."

She said research was increasingly becoming available of the impact of pornography on intimate relationships.

"Women continue to share with me the long-term damage pornography has had on their relationships," Ms Tankard Reist said.

"One woman shared with me how her last four Tinder dates went straight for her throat (choking) without asking."

Port Macquarie mum Peta O'Rourke described the workshop as "important and practical".

"It was great to get real tips on how to deal with some of the things going on in our kids lives."
