In 2025, nearly half of Australia’s school leaders reported being physically assaulted at work. Additionally, almost 54 percent faced threats of violence. These figures come from one of the largest ongoing surveys of principals in the country, and they describe a workforce under siege. The trend line matters more than any single number. Back in 2011, 27.3 percent of principals reported physical violence. By 2025, that figure had climbed to 47.8 percent, an increase of roughly 75 to 80 percent across the 15-year span.

Students account for the vast majority of physical incidents. Meanwhile, parents and caregivers are the predominant source of threats and cyberbullying, making up nearly two-thirds of threats in recent reporting cycles. Taken together, the evidence points to a convergence of forces: post-pandemic social disruption, family trauma flowing into classrooms and a school system stretched past its capacity to respond.

A Generation That Missed the Playground

The pandemic removed something schools quietly provide every day. Recess arguments, group projects and playground negotiations teach children how to manage conflict. Lockdowns interrupted that learning for months at a time, and the effects are now visible in classrooms across the country. Teachers report that student behaviour has deteriorated since the pandemic, with students more distracted and less engaged than before it began. International comparisons sharpen the picture further. According to a major OECD report, Australian classrooms rank among the least favourable for discipline in the developed world.

The escalation also shows up in hard incident data. In New South Wales, the Department of Education recorded 1,517 assaults in schools in 2023, up from 843 the year before. Notably, incidents involving weapons tripled, rising from 241 in 2022 to 728 in 2023. Those numbers describe children who returned to school without the social scaffolding their older peers built over years of ordinary interaction. As a result, aggression fills the gap where regulation skills never formed.

Trauma Walks Through the School Gate

What happens at home arrives at school the next morning. The Australian Child Maltreatment Study makes the scale of that reality difficult to ignore. Young people aged 16 to 24 reported higher rates of harm than any older cohort. Specifically, 34.6 percent experienced emotional abuse, 10.3 percent experienced neglect and 43.8 percent were exposed to domestic violence during childhood. The study also links maltreatment to a range of health risk behaviours and mental health disorders.

The classroom consequence is emotional dysregulation. A child who lives with violence learns that violence resolves conflict. Consequently, teachers inherit behaviour shaped by circumstances entirely outside the school’s control, often without the training or specialist backup to manage it. This is where the school violence conversation commonly goes wrong. Framing the problem as a discipline failure misses the point. In reality, much of what surfaces as aggression in classrooms began as trauma somewhere else.

A System Without the Staff to Respond

Even the best behavioural strategy fails without people to deliver it, and Australian public schools are running short of people. Some 58.1 percent of public school principals report a teacher shortage. That is the third-highest rate in the OECD and more than double the OECD average of 24.9 percent. In lower secondary schools, 41.9 percent of principals say the shortage directly hinders instruction quality, which is almost twice the OECD average. The shortage lands hardest where behavioural needs run highest. OECD data shows 34 percent of students in disadvantaged Australian schools lack sufficient teaching staff, compared with just 3 percent in advantaged schools. Furthermore, nearly 80 percent of teachers report insufficient support for students with additional needs, including shortages of education support staff.

Funding gaps also compound the staffing crisis. Victorian public schools alone are underfunded by 1.8 billion dollars. In a 2024 Victorian survey, 83 percent of principals reported teacher shortages in the previous year and 93 percent said filling vacancies had become harder. Workload data completes the picture. Australian teachers work an average of 46.5 hours per week, compared to an OECD average of 40.8. Almost two-thirds report high stress and more than 80 percent say the job harms their mental health. An exhausted workforce has less capacity to de-escalate, less time to build relationships and fewer reserves when a crisis erupts.

When Parents Become the Threat

One of the more troubling shifts in the data involves adults. Parents and caregivers are now the primary source of threats against school leaders, a pattern the principal wellbeing research confirms year after year. Community stress has found an outlet at the front office. Principals absorb aggression over enrolment decisions, discipline outcomes and resourcing constraints they did not create. Beyond that, the behaviour models something for students as well. Children watch how the adults around them treat their school, and they learn from it.

The Cost Is Now Measurable in Departures

The human toll on school leadership has reached a point that demands policy attention. According to the most recent ACU Principal Health and Wellbeing study, over 54 percent of school leaders consistently report an intent to leave the profession, with the 2025 dataset placing that figure at 54.4 percent. More than 1,000 reported being a victim or witness of physical abuse. A similar number were flagged as at risk of self-harm, occupational health problems or serious impacts to their quality of life. School leaders now show higher rates of anxiety and depression than the general population. Specifically, 25 percent score at least moderate for anxiety and 23 percent for depression. As a result, a profession responsible for the safety of children is itself becoming unsafe to work in.

What Comes Next

The data tells a coherent story. Pandemic disruption created a socialisation deficit. Family trauma, in turn, feeds dysregulated behaviour into classrooms. A depleted, underfunded system lacks the specialist staff to intervene early, and community aggression toward educators removes the goodwill schools once relied on. Each driver is addressable. Full funding of public schools closes the resourcing gap between advantaged and disadvantaged communities. In addition, investment in counsellors, support staff and behavioural specialists gives teachers the backup the data shows they lack. Early intervention programmes that treat trauma as a health issue reduce the load before it reaches the classroom door.

The alternative is already visible in the exit intentions of half the nation’s school leaders. Without intervention, the sector loses the experienced people best equipped to manage the crisis, and the cycle accelerates. The research has done its job. Accordingly, the findings now sit with policymakers, and the window for acting on them is narrowing with every survey that lands.
