Young people's mental health (12–24 years)

Last updated:

Key points

In Australia

Young people aged 16–24 had the highest rates

of 12–month mental disorders.

Females aged 16–24 accessed

Medicare-subsidised mental health services at nearly twice the rate of males in the same age group.

Many young people face barriers

to care including cost, long wait times and limited service access.

Summary

Many mental health conditions first emerge during adolescence and early adulthood, making these years critical for prevention, early identification and timely support (AIHW 2022).

Most young people report good mental health. However, a substantial minority experience mental health conditions that can affect education, employment, relationships and daily functioning. Anxiety disorders are the most common conditions among young people, and females generally report higher prevalence, higher psychological distress and greater use of mental health services than males (AIHW 2025e).

Young people use mental health services across community, primary care and hospital settings. Medicare-subsidised services are the most common entry point, particularly through general practitioners (GPs) and psychologists. Some young people require more intensive care, including emergency department presentations or hospital admissions during periods of acute distress (AIHW 2026b).

Mental health outcomes are shaped by a range of risk and protective factors, including family and social support, access to services, education and employment opportunities and broader social and environmental health conditions. Some population groups, including First Nations young people, those living in rural and remote areas, culturally and linguistically diverse (CALD) young people and LGBTIQA+ young people, experience greater challenges due to structural and social factors (AIHW 2024a; AIHW 2025a; AIHW 2025e).

This page provides a national overview of young people’s mental health using data from the AIHW's Mental Health Online Report and key national surveys, with age groups such as 12–17 or 16–24 years noted for each measure.

Prevalence of mental health conditions

Young people aged 12–24

National survey data consistently show that adolescence and early adulthood are peak periods for the onset of mental disorders (Figure 1). Based on the National Study of Mental Health and Wellbeing, the prevalence of mental disorders among young people aged 16–24 increased from 26% in 2007 to almost 39% in 2020–2022, the highest of any age group (ABS 2008; ABS 2023). Anxiety disorders are the most common mental health conditions among young people, followed by Affective disorders and Substance use disorders (ABS 2023; AIHW 2025e).

Prevalence for people aged 16–85 years has increased slightly over time, but there have been larger increases observed among young people, in particular young females. Between 2007 and 2020–2022, the proportion of females aged 16–24 experiencing a mental disorder increased more sharply than for males of the same age. Females are also more likely to report high levels of psychological distress (AIHW 2025e).

Data for younger adolescents show different patterns. The Young Minds Matter survey indicates that around 14% of young people aged 12–17 experienced a mental disorder in the previous 12 months. In this age group, Attention deficit hyperactivity disorder (ADHD) and Anxiety disorders were the most common conditions. Males were more likely than females to experience disorders such as ADHD, while Anxiety and Depressive disorders were more common among females (Lawrence et al. 2015).

While prevalence estimates vary by data source, age group and survey method, national data consistently show that mental health conditions are common among young people and represent a significant public health issue during adolescence and early adulthood.

Mental health service use among young people

Young people use mental health services across community-based and hospital services, reflecting a wide range of needs from early support to more intensive care. Service use is highest during late adolescence and early adulthood.

Mental health services are funded through a mix of sources, including Australian, state and territory governments, private health insurance and individual contributions. Services are provided by public, private and not-for-profit organisations and may be delivered face-to-face or through digital and telephone services. Together, these services support young people at different stages of need, from early support through to more specialised care, as part of Australia’s mental health system. For more information see Mental health services.

Community-based services

Young people access a wide range of mental health and psychosocial services. These services support prevention, early intervention, treatment and recovery. They include clinical care, community-based supports and practical assistance that helps young people participate in education, work and community life.

Services are delivered through primary care (especially general practitioners (GPs), specialist care (psychologists and psychiatrists), as well as school and university counselling, online and telephone support, youth-specific services (like headspace), community mental health services (Figure 2) and psychosocial supports funded through both mainstream systems and the National Disability Insurance Scheme (NDIS).

Mental health-related prescriptions under the Pharmaceutical Benefit Scheme (PBS), including Antidepressants, Antipsychotics, Anxiolytics, Hypnotics and Psychostimulants, are commonly used as part of community-based mental health care, with most prescriptions issued by GPs. Prescriptions dispensed for ADHD have increased over time, reflecting changes in prescribing patterns observed in national prescription data (Figure 3).

Hospital based services

Some young people require more intensive mental health care that is provided in a hospital setting. This can include presenting to an emergency department (ED) during a mental health crisis or being admitted to hospital for ongoing treatment and monitoring.

ED care provides short-term assessments and stabilisation for young people experiencing acute mental health distress. Following assessment, young people may be discharged, referred to community services or admitted to hospital if further care is needed. In 2024–25, the rate of mental health-related ED presentations was higher among young adults aged 18–24 than adolescents aged 12–17 (169 per 10,000 population compared to 114, respectively), indicating higher use of emergency care for mental health during late adolescence and adulthood (Figure 4) (AIHW 2026b).

Admitted patient hospital care is used when a young person requires treatment or support that cannot be provided without admission. Care may involve same-day treatment or overnight stays in hospital. In 2023–24, females aged 18–24 had the highest rate of overnight hospitalisations with specialised psychiatric care, at 100 per 10,000 population (AIHW 2025c).

Hospital and ED data show that severe mental health episodes among young people often involve mood disorders, psychosis, acute distress or substance-related conditions. These data highlight the impact of severe mental health conditions on young people and the importance of timely prevention, early intervention and follow-up care.

Population groups experiencing greater challenges

Some young people experiencing mental health conditions may also have contact with other service systems, such as homelessness services, child protection or youth justice, reflecting the interaction between mental health, social disadvantage and life circumstances.
