High school students from Northmead and The Hills will be invited to take part in a mental health forum called Young Healthy Minds next May.
The forum was developed in 2009 for Hornsby teenagers after youth service providers found that poor mental health and its social effects were the most significant barriers to employment and education for young people.
2realise partnership broker Steve Cremona said it was a model set to be adopted in Canada and England after it was presented at the 2013 G20 youth summit.
Mr Cremona stressed the importance of destigmatising mental health.
He said topics to be covered at the forum would be determined by teenagers' responses to a Google survey.
"We ended up with 20 or 30 responses straightaway," he said. "It was overwhelming what the kids were requesting.
"They want to know what to do as bystander for people who suffer from anxiety and depression: How do I support them? What do I say? Do I talk about it or not talk about it?
"One of the greatest things about having access to the internet, and one of the worst, is that kids can now pick up their smart phone and self-diagnose themselves. Depression is a real thing for these young people, but we don't want people to talk themselves into it."
Guests will speak about different aspects of mental health at the forum. Students will be asked to reflect on the day's events and name strategies to implement at school. The forum can accommodate up to 300 students.
