About The Authors

Sonya Karras and Sacha Kaluri, authors of this guide for parents, are mothers themselves and have spent their careers working with teenagers.

They are highly sought after professional speakers in the youth sector and experts on teenage issues. They’ve entertained and informed more than one million young people around Australia. Their messages are powerful, funny, insightful and, in some instances, life saving.

As two of Australia’s most sought after professional speakers in the youth market, each present to more than 200 groups of students, teachers, parents and organisations across Australia every year.

Sonya and Sacha are co-founders of The Australian Teenage Expo, which, as one of Australia’s largest youth educational events, tours nationally, motivating and encouraging young people.

They have made it their life's mission to engage and connect with teenagers on a daily basis to guide them in these areas. They believe the more choices, options and information you give a teenager the more likely they are to make positive choices especially when faced with a tricky situation. 

In 2016 Sonya and Sacha took the parent seminars they run in schools to a whole new level releasing a hit national TV show, “The Sonya and Sacha Show.” This 30-minute fun, entertaining and information packed program is directed to parents.
