Takeaway coffee cups will be used to carry messages of hope to vulnerable young people throughout October, which is Mental Health Month.
Sydney cafes have been urged to purchase stickers for their cups with pre-written messages, or develop their own messages for customers.
These include survival tips and words of encouragement for those struggling emotionally.
The campaign is run by Weave Youth & Community Services, a non-profit community organisation that has been working with disadvantaged young people, women, children and families in Sydney's CBD and South for over 35 years.
Weave chief executive Shane Brown said the campaign was aimed at helping people reflect on their strength and resilience, with tips for getting through hard times.
“You don’t need to have suffered a mental illness to pass on or receive valuable survival tips,” Brown said.
“We all experience hard times and through these learn different ways to cope.
“Many people are scared or uncertain about where to turn at the time they need help the most, and mental illness and suicide rates remain too high, particularly among young people.
“Small gestures or words of wisdom can make a huge difference to someone in their moments of need.
“We all see the daily cup of coffee as a bit of a pick me up in the mornings.
"We’re hopeful that the messages on each cup will go above and beyond that – by raising awareness and shining a spotlight on mental health and wellbeing.”
