"It is unreasonable to simply have a 'leave it to schools' approach to take care of the range of social problems that students face," Secondary Principals' Association chair Sheree Vertigan said.
The new survey follows others also pointing to serious drug and alcohol problems among the young and warning of a culture of abuse that continues into adult life.
Almost three-quarters of the schools surveyed had introduced alcohol and drug policies advocating supporting rather than punitive approaches, with most parents involved in management of their child's abuse.
Students using or dealing illicit drugs were generally suspended - or expelled in rare cases - and police were often involved.
Principals and school communities were also worried about mental health and cyber-bullying, which pointed to related "but not obvious" problems regarding more extensive substance abuse problems.
Studies had shown that students using the two major drugs of concern to schools - alcohol and cannabis - were more likely to suffer or carry out cyber-bullying.
"Principals' concerns centred on the significant impact that binge drinking had on the students themselves, their peers and the school generally," the survey said. "Students who drank alcohol and used other drugs came to school late, tired and often with a poor attitude, leading to disruptive behaviour [and] were also in danger of developing a pattern of non-attendance."
Council chairman John Herron said schools needed far more support from governments, communities and the drug and alcohol sector.
In Victoria, the Responsible Gambling Foundation said children as young as 12 tried gambling and became punters at 15.
"A great proportion of Australians growing up today are likely to have experience of gambling before they are 18."
