Beyond Abuse has praised Education Minister Jeremy Rockliff for suspending a Northern Tasmanian teacher and referring historical sexual allegations to police saying they could be "the tip of the iceberg".
Founder and spokesman Steve Fisher has urged anyone who may have been abused by any teacher to come forward.
"You will be listened to and taken seriously so don't worry about speaking out," Mr Fisher said.
"This could be the tip of the iceberg, we hear about a lot of cases and they need to be exposed.
"The change in the past five years has been phenomenal and it is fantastic that survivors are going to be listened to.
"It is like never before, things are so different now, and so much better for abuse survivors than they were."
In other news:
The Australian Education Union has declined to comment on the teacher who was suspended on Wednesday after it was reported that he sexually abused a year 9 student in the late 1980s and got her pregnant.
It is believed he left the school but some years later was re-employed in a government school.
The AEU also would not be drawn on screening measures for teachers.
Mr Fisher commended Mr Rockliff for his decisive action on the case.
"Good on Mr Rockliff for taking quick action," he said.
"He has said the Department of Education did not know of the matter and it is great that the Minister is involved and the matter will be fully investigated.
"Let the police investigate and let's find out what really did happen and how this teacher may have slipped through the cracks."
Mr Rockliff said he had been told the Department of Education did not have previous knowledge of the matter.
The Department of Education referred the matter to police. "I would urge anyone who has any information about child sexual abuse to report it to Tasmania Police," Mr Rockliff said.
The government was unable to say where the man was teaching but it is believed to be in Launceston.
