A major survey conducted in some suburbs and country areas of Victoria revealed that more than half of all teenagers have been a victim of bullying.
High numbers of young people have also admitted trying alcohol, cigarettes and marijuana.
Released on Friday, the 2010 Adolescent Community Profiles gives a snapshot of youth health and social issues for each Victorian municipality, reports the Herald Sun.
Bullying was a big problem in Melton, with 54 per cent saying they had experienced recent incidents.
In southeastern suburbs such as Clayton and Oakleigh the figure was around 51 per cent. The City of Bayside, which includes Brighton and Sandringham, had the lowest incidence, with less than one in three reporting recent bullying.
State Higher Education and Skills Minister Peter Hall said the profiles identified areas of strengths and weaknesses.
"They are designed to guide decision-making across government so we can more effectively set priorities and allocate resources," he said.
The Adolescent Community Profiles include data from the Victorian Adolescent Health and Wellbeing survey of more than 10,000 students.
