The 2019 Student Wellbeing Survey was completed by 28,600 Tasmanian students from grades four to 12.

Fifty-eight per cent of students reported high wellbeing levels with regards to physical bullying though this declined markedly with regards to verbal bullying.

Thirty-six per cent reported a high level of satisfaction with life and just 30 per cent said they had positive feelings about their body.

Fourteen per cent of students believed they had a low sense of wellbeing about safety within their school.

Twelve per cent of grade four students believed they did not receive adequate nutrition before school and 21 per cent expressed concern over their sleeping habits.

Eight per cent of grade four students had body image concerns

At the other end of the spectrum, 38 per cent of year 12 students reported a low level of nutritional wellbeing and 35 per cent reported low levels of sleep.

Thirty-seven per cent of year 12 students had a positive view on future goal planning.

Education Minister Jeremy Rockliff said the survey would be conducted annually and its data would be used to implement student-based and professional learning programs.

"Schools will work closely with families and the broader school community to understand the wellbeing data and use it to positively impact students," he said.

Tasmanian Children's Commissioner Leanne McLean said the size and scope of the survey was a first for the state.

"I certainly look forward to seeing how this data is used to target support to students, and to seeing how this affects students' views of their own wellbeing over time," she said.
