A “PORN star” teacher could keep his job, despite a video of him having sex with an ex-student being posted on an X-rated website.

Just days before school resumes, the Geelong high school at the centre of the storm says it is taking the matter “very seriously”.

The graphic video of the teacher and the student, who graduated in 2008, went viral on social media websites after students discovered it.

A preview video shows the couple naked, in sex acts, and with the girl blindfolded.

The ex-student explained yesterday that everyone who knew them understood the couple were in a committed relationship. The couple live together and jointly own a business.

“We’re consenting adults,” she said.

Oberon High School principal Alison Murphy said she took immediate action when she became aware of the video on Tuesday, but said the video did not change her view of the “successful” VCE teacher.

“He is not here today. It’s uncertain when he will return,” she said. “The matter is under investigation.”

She said the teacher was “well regarded”.

Ms Murphy said it would be inappropriate to suspend the teacher until investigations were completed.

A decision would be made then on his future, but she said there was “absolutely” no evidence the pair had a sexual relationship when the girl was at the school.

Some students dubbed the teacher a hero; others said it was his right to do what he wanted out of school.

RateMyTeachers.com describes him as an intelligent man always willing to help students to their best results. The Department of Education has confirmed it is investigating, and warned of the dangers of cyberspace.

In 2010 students at Western Heights College stole a teacher’s mobile phone, storing a raunchy home video that was circulated.

No charges were laid.
