The ACT Greens say they will work to create more supported accommodation facilities if they are part of the next government.
The $47.5 million mental health package would also expand the Police, Ambulance, Clinician Emergency Response to two teams, seven days per week.
It would also go towards refurbishing 10 beds at Brian Hennessy Rehabilitation Centre and building five additional supported accommodation houses over the next four years.
Greens Mental Health Minister Shane Rattenbury said one third of Canberrans would need support with their mental health at some stage in their lives.
"With the COVID pandemic hitting hard, the Greens know that mental health and wellbeing, support and connectedness is more important now than ever," he said.
"I am pleased that we are establishing Safe Haven Cafes in Canberra, as a response to COVID, and our plan delivers longer funding for this - to help people get peer-led support and avoid ending up in ED unnecessarily.
"The Greens are committed to ensuring all Canberrans can access the right mental health support in place, at the right place, at the right time."
