Please carefully consider your needs when reading the following information about suicide and self-harm. If this material raises concerns for you contact Lifeline on 13 11 14, or see other ways you can seek help.
The information included here places an emphasis on data, and as such, can appear to depersonalise the pain and loss behind the statistics. The AIHW acknowledges the individuals, families and communities affected by suicide each year in Australia.
Aboriginal and Torres Strait Islander readers are advised that information relating to Indigenous suicide and self-harm is included.
The AIHW supports the use of the Mindframe guidelines on responsible, accurate and safe suicide and self-harm reporting. Please consider these guidelines when reporting on statistics on the monitoring of suicide and self-harm.
This, the first delivery of coded ambulance attendance data, includes 1-month per quarter snapshots from Victoria (Vic), Tasmania (Tas) and the Australian Capital Territory (ACT) for 2019, and from the second quarter of 2019 for New South Wales (NSW).
See About to learn more about the ongoing developments relating to ambulance attendance data funded through this project. Data from other participating jurisdictions will be available over the remainder of 2020 and 2021, with monthly data for all jurisdictions available from mid-2021.
Taking into consideration the population differences of the 3 jurisdictions that provided data for all 4 quarters of 2019, the rate of ambulance attendances for suicidal ideation (thinking about killing oneself without acting on the thoughts (Klonsky et al. 2016) ranged from:
84.6 per 100,000 population in Victoria (nearly 5,600 attendances) to 51.8 in Tasmania (about 280 attendances) with the ACT reporting a rate of 80.6 (about 340 attendances) (Supplementary table NASS S.1).
Attendance rates for suicide attempts (non-fatal intentional injury with suicidal intent, regardless of likelihood of lethality (Klonsky et al. 2016) by comparison, were lower than ideation in all 3 jurisdictions. Rates of attendances for suicide attempts ranged from:
64.0 per 100,000 population in the ACT (about 270 attendances) down to 40.1 in Tasmania (about 210 attendances), with Victoria reporting a rate of 53.5 (over 3,500 attendances).
For comparison, the most recent ABS Causes of Death release reports the age-standardised death rate for death by suicide over the period 2014–2018 as being 10.1 per 100,000 for Victoria, 15.4 per 100,000 for Tasmania and 10.7 for the ACT (ABS 2019). The numbers of ambulance attendances for suicide attempts for the 3 months in 2019 in each of these three jurisdictions are substantially higher than the number of deaths by suicide for the entire 12 months in 2018. See Suicide deaths by states and territories.
Ambulances do not attend all deaths therefore fatal suicide (fatal intentional injury with suicidal intent; Klonsky et al. 2016) is under-represented. Rates of deaths by suicide have not been calculated because of small numbers, affecting the reliability of the estimates (see Technical notes for details).
Ambulance attendances for self-injury were the least common among the self-harm and mental health related incidents, likely in part, reflecting differences in the method of harm. In 2019:
Self-injury related ambulance attendances may include a small number of suicidal behaviour attendances (see Technical notes for definitions).
In 2019, the rate of ambulance attendances for self-injury ranged from:
Mental health related ambulance attendances are classified by the presence of a mental health symptom preceding (24 hours) or during the ambulance attendance. See Technical notes for definition.
During a mental health related attendance if there is evidence of self-harm (suicidal ideation, suicide attempt, death by suicide or self-injury) the co-occurrence of these symptoms and behaviours are recorded. The following data report only mental health incidents, some of which will have co-occurring self-harm behaviours.
In 2019, the rate of mental health related ambulance attendances ranged from:
160.0 per 100,000 population in Victoria (nearly 10,600 attendances) down to 135.1 in Tasmania (around 720 attendances); the ACT recorded a rate similar to Victoria (158.4; nearly 680 attendances) (Supplementary table NASS S.1).
There are distinct differences between the sexes when examining deaths by suicide and intentional self-harm hospitalisations; higher rates of deaths by suicide are seen in males compared with females (see Deaths by suicide over time) while females have higher rates of hospitalisations for intentional self-harm—with and without suicidal intent (see Intentional self-harm hospitalisations. Ambulance attendances capture intent (see Technical notes on evidence) and therefore can provide information on the extent of these behaviours in the community.
The interactive data visualisation shows ambulance attendances for males and females by each attendance type and for each of the four states and territories. See how ambulance attendance types vary between the sexes.
Ambulance attendances for self-harm behaviours and mental health, by age and sex, selected states and territories, 2019.
The vertical bar graph shows the crude rate of ambulance attendances for suicidal ideation, suicide attempt, self-injury and mental health for males and females in Victoria for the combined quarterly snapshot months in 2019. Users can also choose to view crude rates and numbers of attendances for New South Wales, Tasmania or the Australian Capital Territory for all or selected self-harm behaviours and mental health. Across the 2019 snapshot months in Victoria, the highest crude rates of ambulance attendances for males and females were for mental health, at around 160 attendances per 100,000 population, followed by suicidal ideation, suicide attempt and self-injury. Crude rates for attendances for self-injury were around 14 for males and around 22 for females.
Rates of ambulance attendances for suicide attempt and self-injury were between 1.5 and 2.1 times higher for females than males. Ambulance attendance rates for females involving a suicide attempt were:
85.3 per 100,000 population in the ACT, 64.6 in Victoria and 46.7 in Tasmania.
By contrast, the corresponding rates in males were:
40.8 per 100,000 population, 41.0 and 32.1, respectively.
Attendance rates for both males and females were highest for incidents relating to mental health. Rates ranged from:
The interactive data visualisation illustrates the distribution of self-harm and mental health related ambulance attendances for both males and females by age. For this visualisation, ambulance attendance data from 2019 in NSW, Victoria, Tasmania and the ACT have been combined.
In general, there were higher numbers of attendances in the younger age groups for both males and females for incidents involving:
suicidal ideation and suicide attempts, in particular, ages 15–19 (about 930 and 800 attendances for females, respectively; around 740 and 310 attendances for males, respectively) and 20–24 years (Supplementary table NASS S.2).
By contrast, mental health related attendances for males were more common in older age groups spanning 25–39 years while those for females tended to be younger (15–29):
Due to the low number of ambulance attendances for deaths by suicide these data cannot be reported by age and sex.
Ambulance attendances for self-harm behaviours and mental health, by age group and sex, selected states and territories, 2019.
The butterfly chart shows the distribution of the number of ambulance attendances for suicide attempts by age group for males and females for quarterly snapshot data collected in Victoria, Tasmania and the Australian Capital Territory in March, June, September and December 2019 and in New South Wales in June, September and December 2019. Users can also choose to view ambulance attendance numbers by age group for suicidal ideation, self-injury and mental health. The number of attendances for suicide attempts generally decreased with increasing age group from 15–19 for both males and females. Females aged 15–19 had the highest number of ambulance attendances for suicide attempts, 793 attendances across the snapshot months for the selected states and territories.
