Ms Contos, 26, founded the organisation four years ago after an Instagram post went viral and alerted her to the dire need for mandated consent education in Australian schools.
"Australia is really leading the way in terms of focusing on preventing sexual violence," she told AAP.
"There is an important message to be shared overseas about what is happening in Australia and what lessons can be learned for other countries."
The PCI has been funded by the Department of Social Services as part of the ten-year National Plan to End Gender Based Violence launched in 2022.
The initiative is the first of its kind in Australia to use social media to reach young people through users they know and trust.
More than 25 influential young Australians from footballers to beauty vloggers have signed up to demonstrate the importance of having vulnerable and open conversations about consent.
"We wanted to make sure that young people were hearing this messaging online from people they already knew and trusted," Ms Contos said.
"It was really important that the people delivering these messages were peers and also role models."
The resources are available in a variety of formats including podcasts, TikToks, Instagram posts, essays and YouTube videos.
They have been translated into six languages other than English and specific resources for First Nations communities are also in development.
Parents and educators are being encouraged to use these resources to start conversations around respectful relationships with young people.
Child sexual abuse by adolescents aged under 18 has increased in recent years, with nearly one in five Australians experiencing sexual abuse by an adolescent before they turn 18.
The increased accessibility to pornography and the fact it was being used as sex education was contributing to these rates, Ms Contos said.
"In recent years what has changed the most is the influence of the manosphere and algorithms," she said.
"These challenges are rising quicker than we're making progress so we're going to need to be creative and innovative in terms of how we provide holistic educational resources to young people on these issues."
