A petition was quickly launched in support of the assistant principal, who has been with the school 15 years.
Lisa Rodgers, Department of Education director general, said after careful examination of the facts, Mr Walton would return to his position.
“I understand it’s not always easy for teachers, in the heat of the moment, to make decisions about how to restore order in a difficult situation,” she said.
“However, as I said yesterday, I would not recommend that teachers physically restrain students in the way we have seen in the video.”
Mr Walton received a hero’s welcome from community members when he returned to work on Thursday, after nearly two months away from the school.
“I love being here, I love being with you, it’s great to see so many ex-students and so many parents coming down to help support us out here at the school, I really appreciate your support,” he said.
“I’m overwhelmed … I struggle to find the words to say thank you”
She said Mr Walton would be receiving further training in managing student conflict and anti-social behaviour.
“The community has really gotten behind Mr Walton – and indeed the wider teaching profession – and I look forward to seeing him back at work.
“We now need to let him and the entire school get on with the business of teaching and learning, in the interests of students and everyone concerned.”
The online petition, started by a student, claimed the incident involved an ex-student and another student. It called for Mr Walton to be reinstated, and received thousands of signatories within a short period.
State School Teachers’ Union president Pat Byrne said the incident reinforced more broadly the urgent need for the government to properly resource a strategy around student violence, such as the 10-point plan announced by the Education Minister early this year.
“There was no additional funding for this strategy in the state budget last week, meaning that schools are expected to continue to do without specialist programs, teacher professional development and sufficient suitable alternative placements for students who need them,” she said.
“Principals and teachers are rightly disappointed in the lack of follow up to the policy changes which were announced with such fanfare at the beginning of the year.”
It is understood there will be no charges laid over the incident.
