Everyday Victorians will influence the scope of the state's royal commission into mental health.
Public submissions on the terms of reference will be accepted from Friday until January 27 at engage.vic.gov.au, while consultation with organisations has already started.
"Every year, one-in-five Victorians experiences a mental illness and the truth is we can do more to improve the system," Mental Health Minister Martin Foley said.
"I encourage anyone who has experience with mental illness or our state's mental health system, to take this opportunity to have their say on the terms of reference and help us set the tone for this life-changing reform."
Commissioners for the $13.2 million inquiry, the first of its kind in Australia, are still being sought.
The royal commission will begin in March.
This week, annual reports for both the Coroner's Court and Mental Health Complaints Commissioner were published, touching on issues within the system.
Last financial year, 688 people took their own lives, according to the Coroner's Court, up from 672 the year before.
The report also highlighted four case studies of people taking their own lives while they were inpatients at mental health units.
Three of the cases raised concerns about access to ligatures and hanging points within the units.
More than 2120 inquiries and complaints were made to the Mental Health Complaints Commissioner in 2017-18, up 21 per cent on the year before.
Most were about people's recent experiences in the public mental health services, according to the commission's annual report.
Prisoners also made 688 calls to the office, concerned about mental health treatment in the corrections system and were mostly about immediate access to treatment and medication when being held on remand.
