Lifeline Australia says it has seen an uptick in extreme weather events impacting the mental health of people across the country.
A poll it released on Thursday found 53 per cent of those surveyed had changed their behaviour because of stress related to extreme weather.
This includes where they live or work, withdrawing from social activities, or giving up hobbies such as gardening; playing or watching sports; and seeing friends.
The poll, which canvassed the views of 1500 people, also found 40 per cent said their mental health or that of someone they know was harmed.
"That strikes me as being really critical knowledge," Lifeline chief research officer Anna Brooks said.
"We know now from the data, this can really affect their risk of suicide."
Lifeline Australia receives 400 calls per day to its dedicated 13HELP phone number for people impacted by natural disasters.

"Campfires were always quite a comforting smell for me, and now it carries with it a bit of anxiety and a bit of stress when I smell anything smoky," she said.
The overlap between the country's burgeoning mental health crisis and climate change was apparent for Rebecca Huntley of think-tank 89 Degrees East, which conducted the research.
"This is not just a couple of nervous Nellie climate activists who are suffering from eco-anxiety," Dr Huntley said.
"Extreme weather events are changing the way that Australians live."
