Mental health is a key component of overall health and wellbeing (WHO 2013). The National Survey of Mental Health and Wellbeing conducted in 2007 found that an estimated 1 in 5 (20%) Australians aged 16–85 experienced a mental disorder in the previous 12 months (ABS 2008). A mental illness can be defined as ‘a clinically diagnosable disorder that significantly interferes with a person’s cognitive, emotional or social abilities’ (COAG Health Council 2017). The term itself covers a range of illnesses including anxiety disorders, affective disorders, psychotic disorders and substance use disorders.
However, a person does not need to meet the criteria for a mental illness or mental disorder to be negatively affected by their mental health (COAG Health Council 2017; Slade et al. 2009). Mental health affects and is affected by multiple socioeconomic factors, including a person’s access to services, living conditions and employment status, and affects not only the individual but also their families and carers (Slade et al. 2009; WHO 2013).
The National Survey of Mental Health and Wellbeing was a program of 3 targeted mental health epidemiological surveys that based their classification of mental disorders on existing diagnostic criteria to estimate prevalence (ABS 2008). The 3 surveys included the National Survey of Mental Health and Wellbeing, the National Survey of People Living with Psychotic Illness and the Australian Child and Adolescent Survey of Mental Health and Wellbeing (AIHW 2020). The data obtained from these surveys are due to be updated from 2020–21 as part of the Intergenerational Health and Mental Health Study, which will consist of 4 surveys over 3 years (ABS 2019; AHHA 2019). The National Study of Mental Health and Wellbeing will update the data on the prevalence of mental disorders from 2007. Another source of information about the mental health of Australians is the ABS’s National Health Survey 2017–18, which provides data on a range of health conditions including mental and behavioural disorders. The National Health Survey estimates are based on self-reported data, and record a participant as having a mental or behavioural condition during the collection period only if it was also reported as long-term (had lasted, or was expected to last, a minimum of 6 months) (ABS 2018).
Together, these surveys provide an overview of the prevalence of mental disorders in Australia.
The National Survey of Mental Health and Wellbeing 2007 estimated that:
The National Survey of People Living with Psychotic Illness 2010 estimated that:
The Australian Child and Adolescent Survey of Mental Health and Wellbeing 2013–14 (Young Minds Matter) estimated that, in the 12 months before the survey:
The National Health Survey 2017–18 estimated that:
This chart shows the proportion of persons with a mental or behavioural condition in 2017–18 by age group and sex. For persons aged 0–14 years, males have a higher rate of current long-term mental or behavioural conditions than females. In all other age groups, females have a higher rate than males. This difference is most pronounced for those aged 15–24.

Mental health affects not just the individual but also the wider community. The total burden of a disease on a population can be defined as the combined loss of years of healthy life due to premature death (known as fatal burden) and living with ill health (known as non-fatal burden). Mental and substance use disorders contributed 12% of Australia’s total burden of disease in 2015, making it the fourth highest disease group contributing to total burden. Of the total burden caused by mental and substance use disorders, 98% was due to living with the effects of these disorders (AIHW 2019). Mental and substance use disorders were the second highest disease group contributing to non-fatal burden (23%) after the first-ranked musculoskeletal conditions (25%). See Burden of disease.
There is a substantial difference in the burden of mental health on Aboriginal and Torres Strait Islander Australians compared with non-Indigenous Australians. In 2011, the years of healthy life lost per 1,000 people due to mental and substance use disorders among Indigenous Australians was 2.4 times the rate for non-Indigenous Australians (57.8 compared with 23.6) (AIHW 2016). See Indigenous health and wellbeing.
For individuals who have a mental illness, suicidality—a term that encompasses suicide plans, attempts and ideation—is more prevalent than for those who have no mental illness. According to the National Survey of Mental Health and Wellbeing in 2007, almost 1 in 12 (8.6%) people with 12-month mental disorders reported being suicidal in the 12 months prior to the survey; 0.8% of people without a 12-month mental disorder reported suicidality in that same period (Slade et al. 2009). Overall, 72% of people who exhibited suicidality had a 12-month mental disorder (ABS 2008). See Suicide and intentional self harm for more information on suicide in Australia.
A person may also have more than 1 type of condition at a time. The 2007 National Survey of Mental Health and Wellbeing estimated that 3.2% of Australians aged 16–85 had experienced more than 1 mental disorder in the previous 12 months, and 11.7% had experienced a mental disorder and a physical condition in the previous 12 months (ABS 2008). See Physical health of people with mental illness for more information.
