Bullying is defined as repeated harmful behavior that involves a power imbalance. It can take verbal, physical, social, or psychological forms. Bullying affects about 1 in 10 Australian school children and has negative impacts on both victims and bystanders. Boys report being bullied more often than girls. With age, reported bullying declines slightly but attitudes toward victims become less supportive. Research highlights the importance of schools providing safe, caring environments and resilience-building opportunities to help prevent bullying.
