Young Australians aged 16 to 25 are trying to kill themselves, self-harming, and having suicidal thoughts more than before. A new study led by Dr Katrina Witt from the University of Melbourne and youth mental health hub Orygen found Generation Z faces the highest risk. Data from 14,753 people shows Gen Z starts these behaviors younger than other groups. Kids Helpline data reveals that children as young as six are expressing suicidal thoughts. CEO Tracy Adams said 11% of 10-year-olds contacting Kids Helpline in 2025 reported suicidality, up from 4% in 2012. For 11-year-olds, the rate rose from 3% to 15% in the same period. The average age of kids needing suicide crisis support has dropped from 24 in 2012 to 16 in 2025. The study found that for Gen Z, seeing parental violence and exposure to suicide online or among friends increases risk. Older generations showed links to childhood abuse and substance issues. Dr Witt said, "There is no single cause" and stresses the need for action beyond health services, mentioning economic stress, climate fears, and Covid effects. Nieves Murray, CEO of Suicide Prevention Australia, said these issues are "more acute" for Gen Z. Among Gen Z, 20.2% had suicidal thoughts, 9.2% made plans, 20.4% self-harmed, and 6% tried suicide. Across all ages, the figures were lower. Experts call for early help in schools and communities. Dr Witt said, "We need resources to recognize and respond to distress, and support parents to reduce conflict." Tracy Adams states, "These are children trying to survive overwhelming pain." Safe spaces online and offline are vital. For help in Australia, call Lifeline at 13 11 14 or Kids Helpline 1800 55 1800. Other international helplines are available as listed.
