Suicide and intentional self-harm are complex and can have multiple contributing factors. Although suicide and intentional self-harm are complex issues, they can be prevented.
Where to find help and support
The AIHW respectfully acknowledges those who have died or have been affected by suicide or intentional self-harm. We are committed to ensuring our work continues to inform improvements in both community awareness and prevention of suicide and self-harm. This page discusses suicide and presents material that some people may find distressing. If this report raises any issues for you, support services can help. Crisis support services can be reached 24 hours a day.
Mindframe is a national program supporting safe media coverage and communication about suicide, mental ill health and alcohol and other drugs. Resources to support reporting and professional communication are available on the Mindframe website.
Visit Suicide & self-harm monitoring for information on suicide and self-harm data.
Suicide is an action taken to deliberately end one’s own life, while intentional self-harm is deliberately causing physical harm to oneself but not necessarily with the intention of dying.
The assembling and national reporting of deaths by suicide has up to an 18-month time lag.
The Australian Bureau of Statistics (ABS) collects demographic and cause of death information on all registered deaths in Australia from the states and territories. These deaths are then reviewed 12 and 24 months after initial processing so that any change in information regarding the deceased’s intention to die can be updated (ABS 2021). Visit 2021 ABS Causes of Death for more information.
Suicide registers that exist in several jurisdictions can provide more timely data on suspected deaths by suicide. Data from these registers will not be publicly available unless the relevant jurisdiction decides to release data. Whilst they are not directly comparable with data released by the ABS, the differences are generally small (approximately 95% accurate or better). Visit Suspected deaths by suicide to learn more about suicide register data.
In 2021, there were 3,144 deaths by suicide – an average of about 9 deaths per day. The age standardised rate was 12.0 deaths per 100,000 population, which is down from 13.2 in 2017. Since 1907, the male age-standardised suicide rate has been consistently higher and more variable than the female rate (Figure 1). Variations in the overall suicide rate in Australia have been largely driven by changes in the male suicide rate.

While there has been a rise in the use of mental health services and an increase in psychological distress during the COVID-19 pandemic, COVID-19 has not been associated with a rise in suspected deaths by suicide in 2020 and 2021. National mortality data published by the ABS show that the preliminary rates of death by suicide in Australia were lower in 2020 (12.1 per 100,000 population) and 2021 (12.0 per 100,000 population), compared to revised data in 2019 (13.1 per 100,000 population).
Data on suspected deaths by suicide in 2020 and 2021 have been released for Victoria, Queensland and New South Wales from their respective suicide registers. The Coroners Court of Victoria reported that the number of deaths in Victoria suspected to be from suicide in 2021 (693) was similar to 2020 (691), 2019 (699) and 2018 (697) (Coroners Court 2022).
Leske et al. (2022) reported that while there were some variations by sex and age in the age-standardised suspected suicide rate in Queensland, there was no evidence of an increase since the onset COVID-19 pandemic and restrictions.
The New South Wales Suicide Monitoring System reported 918 suspected deaths by suicide in NSW in 2021. This is higher than the number of deaths reported for 2020 (901) but lower than for 2019 (946) (NSW Health 2022).

Suicide deaths by sex, Australia, 1907 to 2021.
The line graph shows age-standardised rates of suicide for males, females and persons from 1907 to 2021. Users can also choose to view the number of deaths by suicide and male to female rate ratios from 1907 to 2021 and median age at death by sex from 1964 to 2021. The data can be viewed for any period between the years for which data are available.
Numbers and rates of deaths by suicide change over time as social, economic and environmental factors influence suicide risk. The data visualisations below provide an overview of the characteristics of people who have died by suicide in Australia since 1907. This analysis may provide useful information on potentially preventable factors, such as restricting access to means of suicide and reducing the risks posed by social or economic factors. Over time, the accuracy and quality of the data collected have been influenced by a number of factors including changes in legislation, technology and a reduction in social stigma.
Figure 2 shows age-specific suicide rates for males are higher than those for females across all reported age groups for all years.
The age distribution of deaths by suicide is similar for males and females, and the highest proportion of deaths by suicide occur during mid-life. More than half of all deaths by suicide (53%) in 2021 occurred in people aged 30–59 with 1,653 deaths, while 24% of suicide deaths occurred in people aged 60 and over (763 deaths), and 22% occurred in people aged 15–29 (695 deaths) (AIHW 2022). Suicide was the leading cause of death among people aged 15–44 in 2021 (ABS 2022).
The highest suicide rate for males in 2021 occurred in those aged 85 and over (36.4 deaths per 100,000 population). This is followed by males aged 80–84 (31.2) , and males aged 50–54 (26.9). The highest suicide rate for females was among those aged 50–54 (9.5 deaths per 100,000 population), accounting for the highest proportion of deaths by suicide for females (10%).

Suicide deaths by age and sex, Australia, 2021.
The bar chart shows the age-specific rates of suicide for males and females by age groups (five year age bands from 15–19, 20–24, etc to 80-84 and 85 and over). Users can choose to view numbers of deaths by suicide for males and females in these age groups. Data can also be viewed by year from 1907.
The number and rate of deaths by suicide differs between states and territories and across different regions of Australia.
Patterns of deaths by suicide between states and territories can reveal insights that may be masked by results for the whole of Australia and may help to highlight different risk factors and assist in better targeting of suicide prevention activities.
In 2021, the age-standardised suicide rate ranged from 10.1 per 100,000 population in Victoria to 18.4 in the Northern Territory. The highest number of deaths by suicide was in New South Wales (880), followed by Queensland (783), Victoria (675), Western Australia (389) and South Australia (226).

Age-standardised rates of Indigenous deaths by suicide have increased over time, from 22.7 per 100,000 population in 2013 to a peak of 27.9 in 2020 and declining slightly to 27.1 in 2021. This is more than double the rate for non-Indigenous suicide deaths in 2021 (11.8). In 2021, 196 Aboriginal and Torres Strait Islander people died by suicide.
In the five years from 2017 to 2021, suicide rates for Indigenous Australians were highest for those aged 25–44 with 47.6 per 100,000 population. In comparison, the suicide rate across 2017 to 2021 for non-Indigenous Australians in the same age group was 16.2 per 100,000 population.
Suicide rates for young Indigenous Australians, aged 24 years and under, in the five years from 2017 to 2021 (16.6 per 100,000 population) were more than 3 times as high as non-Indigenous Australians in the same age-group for this period (5.3 per 100,000 population).

In Australia, there were more than 29,900 cases of intentional self-harm hospitalisations in 2020–21.
Understanding the scale of the problem of intentional self-harm in Australia is difficult because many cases of self-harm are unreported, unless medical treatment is required.
Only those patients admitted to hospital for intentional self-harm are currently routinely reported in national data sets. Hospital admissions data are collated as an annual release with a 12-month lag. Data are also available from ambulance attendance records and national population surveys such as the Australian Child and Adolescent Survey of Mental Health and Wellbeing (Department of Health 2015).
Visit Intentional self-harm hospitalisation and Ambulance attendances for more information.
Rates of hospitalisations for intentional self-harm are higher for females. This is the opposite of what is seen in deaths by suicide, where rates are higher for males. This may, in part, be due to differences between methods used by males and females – with males tending to use more lethal methods than females.
The rate for females aged 0–14 increased from 41 per 100,000 population in 2019–20 to 70 in 2020–21.
In 2020–21 the age and sex-specific rate was highest for females aged 15–19 (698 hospitalisations per 100,000 population), followed by females aged 20–24 (363 per 100,000 population). For more information see Intentional self-harm hospitalisations by age groups.
Intentional self-harm hospitalisations by age and sex, Australia, 2008–09 to 2020–21.
The bar chart shows the age-specific rates of intentional self-harm hospitalisations for males and females for specific age groups and all ages combined in 2020–21. Users can also view age-specific rate, numbers and the proportion of hospitalisations for intentional self-harm by sex for each age group and year from 2008–09 to 20209–21. In 2020–21, females had higher rates of hospitalisation for intentional self-harm than males up to age 75–79. The highest rates for females were in the 15–19 years age group (697.7 hospitalisations per 100,000 population) and the 15–19 years age group for males (173.5).
The rate of intentional self-harm hospitalisations varied between states and territories in 2020–21, with the Northern Territory reporting the highest rate (238 hospitalisations per 100,000 population), which is more than double the national rate (116 hospitalisations per 100,000 population). The lowest rate was recorded in New South Wales (77 hospitalisations per 100,000 population). Reporting is based on a patient’s usual residence, not necessarily where they received treatment.

Understanding the geographical distribution of hospitalisations due to intentional self-harm based on patients’ area of usual residence can help target suicide prevention activities to areas in need.
A similar pattern was seen with deaths by suicide as age-standardised suicide rates tended to increase with remoteness of place of residence. For more information visit Deaths by suicide by remoteness areas.
