EMBARGOED UNTIL TUESDAY 28 OCTOBER 2025
As Australia braces for a brutal summer, leading doctors will on Tuesday visit Parliament House to warn that worsening climate change is driving a mental health crisis — and will call for mental health to be front and centre in Australia’s climate and health policies.
The serious climate impacts that Australians are already experiencing include:
-
October heat records being broken in several states already
-
Algal bloom in South Australia
-
Drought in regional Victoria
-
High insurance premiums for increased flood risk, with one in six homes at risk of flooding today.
Since the release of Doctors for the Environment Australia’s How climate affects mental health in Australia report earlier this year, DEA will launch an updated version showing new evidence that climate change is already harming Australians’ mental health, with impacts projected to become severe by 2050.
Our leaders can reduce climate distress by showing meaningful action to protect people from heat and extreme weather now, and by rejecting new and extended fossil fuel projects.
The event at Parliament will be hosted by Parliamentary Friends of Climate Action, which is co-chaired by Zali Steggall MP, Jerome Laxale, MP, and Senator Maria Kovacic.
Dr Kate Wylie, GP and Executive Director of DEA
“Our changing climate is making both our bodies and minds sicker. Doctors see the clear links between climate change, physical illness, and mental health. Conditions like asthma and heart disease — both exacerbated by rising temperatures and pollution — are closely tied to anxiety and depression.
“Climate change is putting mothers and children at risk in ways that have lifelong consequences. Complications during pregnancy, including pregnancy loss, premature births and low birth weight are devastating. And the rates of children who are born prematurely or with low birth weight have higher rates of mental disorders as well as those of the developing brain and nervous system.
“Even witnessing a parent in danger during a disaster can cause PTSD in children. The effects can last well into adulthood.”
Dr Cybele Dey, Child and Adolescent Psychiatrist
“Hotter days are linked with more suicides, more domestic violence and more mental health emergencies. In Australia, even mild heat has been shown to increase suicidal distress among young people, with more presenting to Emergency Departments the hotter it becomes. With suicide the leading cause of death for 15-44 year olds -we need to act to prevent suicidal behaviour by reducing heat exposure now and address the underlying driver, fossil fuels, to save lives into the future.
“People in rural and remote areas, especially farmers, are particularly vulnerable as they face both more extreme weather and limited access to care. We need to recognise that climate adaptation is mental health prevention — safe, cool homes, trustworthy information on staying healthy and safe, and local mental health care for the long term can save lives.
“Extreme weather can disrupt community mental health services. As healthcare professionals, we see increased mental health emergency department presentations and hospital admissions with hotter weather, which increase as the heat increases”

Facts on mental health impacts
-
Increased rates of physical illness, like asthma and heart disease, which are both linked with mental disorders - asthma with anxiety disorders and heart disease with major depression
-
Complications during pregnancy, including pregnancy loss, premature births and low birth weight
-
Children who are born prematurely or with low birth weight have higher rates of mental disorders as well as those of the developing brain and nervous system. Rates of these outcomes have increased over the time of increased exposure to extreme weather (a known risk factor)
-
For children, the experience of having a parent or caregiver’s life threatened during an extreme weather event can lead to post-traumatic stress disorder (PTSD), even if the child themselves was not under direct threat.
-
Increased suicide rates with increased annual temperatures. An Australian study showed that young people presented with suicidal thoughts and behaviour even with mildly hot weather and these worsened the hotter it became. With suicide the leading cause of death for 15-44 year olds - the potential to prevent suicidal behaviour by addressing risk factors is crucially important
-
Hot weather and heat waves are associated with increases in physical and sexual assaults and with domestic violence - access to cool shelter and sustainable ways to stay cool, rental standards and safe community spaces which are cool could also make a difference
-
People living in rural and remote communities are at increased risk of mental health impacts, and have lower levels of funding, resources and more fragmented mental health care over time. Farmers and others whose livelihood depends on primary production and stable climatic conditions, also represent a group at increased risk
-
Presentation can occur months or years following the acute traumatic event from extreme weather, and childhood exposure is linked to an increased risk of mental disorders as an adult.
-
Extreme weather events impact mental health care both by disrupting access to community mental health care and increasing the need for mental health care.
There is clear evidence of increased mental health emergency department presentations and hospital admissions with hotter weather, which increase as the heat increases.
