In a Mayoral Minute to Tuesday's council meeting, Cr Baker said the document promotes a common language in mental health, mental illness and suicide and equips organisations and individuals with a set of eight principles to support how we respond to and communicate about suicide.

"The charter takes a unified approach to guide the way we talk about mental health and wellbeing, social and emotional wellbeing, mental ill health and suicide prevention with each other and the community and I am calling on Councillors to support it," she said.

The charter was launched by Health Minister Greg Hunt in 2018.

"We all have a role to play in reducing stigma around mental ill health and suicide, while also promoting help-seeking behaviour through the charter's guiding principles and messages.

"The Charter sets the national standard for how we communicate about suicide and mental health in a way which reduces and avoids stigmatisation," Cr Baker said.

By providing a national benchmark for how we talk about suicide and mental health, each individual or organisation who signs is directly encouraging help-seeking behaviour in vulnerable individuals and helping reduce the prevalence of stigma.
