When Australians talk about the mental health system, they tend to reach for the national average. About one in five Australians will experience a mental disorder in any given year. It sounds manageable. It even sounds like progress. But averages flatten what they measure. Break the numbers down by age and something uncomfortable comes into view. Young Australians aged 16 to 34 are not experiencing a milder or earlier version of the same problem as their parents and grandparents. They are dealing with a different crisis altogether, one the system was not designed around and still has not caught up to. Here we highlight five charts from the ABS National Study of Mental Health and Wellbeing showing where the crisis is concentrated, how severe it really is, and why so many young Australians keep falling through the gaps.
The national 12-month mental disorder rate of 21.5% is the figure that tends to appear in policy documents and media coverage. But that figure is a mathematical average of a deeply uneven distribution. Australians aged 16 to 24 experience mental disorders at a rate of 38.8%, nearly four times the rate of those aged 65 to 74. The national average, in this sense, describes almost nobody accurately. It understates the crisis for young people and overstates it for older Australians.
Psychological distress, measured using the Kessler Psychological Distress Scale, tells a more granular story about severity. Among Australians aged 16 to 24, 34.2% of women experience high or very high distress, compared with 18.0% of men the same age. That gap is real and significant. But the more striking pattern is what happens as both lines travel across the age groups. Distress falls steadily for everyone as they get older. This raises a harder question: are older Australians genuinely in better mental health, or have they simply stopped being counted?
Looking at the full distribution of distress levels reveals how concentrated the burden is among the young. Among 16 to 24 year olds, only half report low distress. The other 50% sit somewhere on a spectrum from moderate to very high. By contrast, three quarters of Australians aged 75 to 85 report low distress. The country’s oldest citizens are, by this measure, its most mentally well. Its youngest are carrying a load the system was not built for.
If the first three charts describe the scale of the problem, this one describes the failure of the response. Among Australians aged 16 to 34 with an active mental disorder, only 9.9% of men and 19.6% of women consulted a health professional. Meanwhile, 17.1% of young men and 16.9% of young women with a disorder saw nobody at all. The pattern runs the other way with age. Older Australians with mental disorders are proportionally more likely to seek help. The system is most accessible to the people who need it least.
Among Australians with a 12-month mental disorder who sought no professional help, the most commonly reported unmet need was counselling. 20.8% of women and 14.2% of men said they needed it and did not receive it. This is not a story about people who do not want help. It is a story about people who know exactly what they need and cannot get it. The barriers are not primarily about awareness. They are structural: cost, availability, waitlists, and a system that has not kept pace with what young Australians actually need.

About this data
All figures are drawn from the
ABS National Study of Mental Health and Wellbeing, 2020-2022, released
October 2023. The survey covered a nationally representative sample of
Australians aged 16 to 85 living in private dwellings. Mental disorders
were assessed using the Composite International Diagnostic Instrument
(CIDI 3.0) and psychological distress was measured using the Kessler
Psychological Distress Scale (K10). Some cells have been randomly
adjusted by the ABS to avoid disclosure of confidential data. Figures
may not add to 100% due to rounding.
