Caution:
This site includes information about child deaths, which some readers may find distressing. If you need support, free and confidential help is available.
We wish to convey our sincere condolences to the families and friends of the infants, children and young people in NSW who have died. It is our foremost responsibility to learn from these deaths and to use that knowledge to make a difference.
A death is classified as suicide when there is clear evidence that the child deliberately intended to end their own life and understood the finality of death. We recognise the sensitivity and complexity involved in determining intent for a child or young person.
We classify deaths as suicides where:

In 2022 and 2023, 49 children aged 10–17 years died by suicide, an average mortality rate of 3 per 100,000 over the 2-year period.
Unlike other causes of death that continue to decline, suicide remains a leading cause of death among young people aged 15–17 years.
We found that:
In 2022 and 2023, 76% (37) of the children who died by suicide experienced a proximal event such as a relationship breakdown, an altercation with a family member or peer, suspension/expulsion from school or cyberbullying/sextortion.
In 2022 and 2023, 98% (48) of children who died by suicide had at least 1 individual factor such as interpersonal difficulties, mental health conditions, substance misuse and/or issues associated with sexual orientation/gender identity. Most of these young people had 2 or more individual factors and 10 young people had between 5 and 7 individual factors.
Family factors that have been associated with suicide include family breakdown or poor family cohesion, family conflicts or violence, and adverse or traumatic events in childhood. In 2022 and 2023, 67% (33) of children who died by suicide had at least 1 family-related factor.
In 2022 and 2023, 76% (37) of the children who died by suicide had at least 1 school-related factor such as absenteeism, suspension or expulsion, learning challenges, and engagement difficulties

Over the 15-year period, the suicide mortality rate increased overall, with a sharp rise between 2010 and 2015.
From 2022 onward, the rate declined by 23% from its 2019 peak (3.81 deaths per 100,000), returning to pre-2015 levels.
Males had consistently higher rates compared to females; however, the rate for females has increased.
While young people aged 15–17 years continue to make up the majority of deaths, the rate for children aged 10–14 increased.
The rate for Indigenous children was higher than for non-Indigenous children.
Children living in regional and remote areas had higher rates compared to those living in major cities.
The average proportion over the 15 years for children (10–17 years) who died by suicide and had a child protection history was 45%.
Most young people who died by suicide were known to services and had been identified as at risk.
We have reviewed evidence about the relationship between school connectedness and suicide risk. Data from the NSW Register of Child Deaths, recent research and a 2024 NSW Coronial inquest highlight the importance of school connection as a protective factor for children and young people against suicide and other risks and indicate the need for further research in this area.

We commissioned the Australian Institute for Suicide Research and Prevention to review suicide clusters among school-aged children. The review examines the patterns and contributing factors in these clusters. It also considers how effective NSW prevention and postvention programs are in reducing risk and supporting recovery after a suicide death.

Aboriginal and Torres Strait Islander children are over-represented in suicide deaths of children aged 10–17 years. Over the 15-year period 2009–2023, the NSW Register of Child Deaths recorded the deaths by suicide of 349 children, of whom 41 (12%) were identified as First Nations children.
In 2021, the CDRT commissioned the Ngarruwan Ngadju First People Health and Wellbeing Research Centre at the University of Wollongong to conduct research to identify opportunities for preventing and reducing the suicide deaths of Aboriginal and Torres Strait Islander children and young people.
The project includes:
The results of this study will be published on this website on 1 December 2025 as Holding Hope: Preventing Suicide among Aboriginal and Torres Strait Islander Young People in New South Wales, accompanied by a community report about this research. On this date, the reports will begin to be shared with First Nations communities and stakeholders.
What we aim to understand
This project explores the factors, behaviours, and circumstances surrounding suicide-related deaths of young people in NSW aged 10–17 who identified as LGBTIQ+.
The goal is to gain a deeper understanding of these deaths, and identify ways to prevent or reduce the likelihood of similar deaths in the future.
What the research involves
The project combines three complementary strands of work:
Why it matters
LGBTIQ+ young people may face unique social and emotional challenges that increase their vulnerability to suicide. This research will help build a clearer picture of those challenges, identify where support systems need strengthening, and inform more inclusive, responsive approaches to suicide prevention among this cohort in NSW.
Our recommendations focus on evidence-informed prevention, cultural safety, and system collaboration.
The Mental Health Commission (as well as the Aboriginal Suicide Prevention Council and the Suicide Prevention Council, when advising the Commission) consider the findings of the Holding Hope: Preventing Suicide among Aboriginal and Torres Strait Islander Young People in New South Wales report, including for the purpose of:
Noting the increasing rate of death by suicide for children younger than 15 years, and for female children their rates of self-harm, the NSW Government ensure that the statewide suicide prevention plan and statewide Aboriginal suicide prevention plan under the Suicide Prevention Act 2025, and any new mental health initiatives, contain measures focused specifically on children younger than 15 years and targeted towards addressing risk factors (including individual and societal).
Noting the increasing rate of death by suicide for children younger than 15 years, and for female children their rates of self-harm, the Australian Government ensure that any actions and initiatives that support the National Suicide Prevention Strategy 2025–2035, and any new mental health initiatives aimed at children and young people, contain measures focused specifically on children younger than 15 years and targeted towards addressing risk factors (including individual and societal).
The NSW Government should include in any suicide prevention plan specific measures targeted to school-aged children and young people across the spectrum of need. In particular, this should include:
The NSW Department of Education, the Association of Independent Schools of NSW, and Catholic Schools NSW conduct joint research to better understand and respond to school disconnection as a suicide and other related risk factor. This research should involve those with lived or living experience of school disconnection and/or youth suicide.
