A male high school teacher accused of making a pornographic movie with a former female student has resigned.
The teacher resigned from his post at Oberon High School, in Geelong, amid an ongoing Victorian Education Department investigation of the incident.
He was accused of making the pornographic video with a former student, who is now aged 21, but was not accused of having an inappropriate relationship while the girl was a student.
Oberon High School principal Alison Murphy said on Wednesday the teacher had given her his resignation and she had accepted it.
"Obviously this has been a very disruptive time for our school community, and so I am hoping our school community can now continue to focus on providing all our students with the best possible education," Ms Murphy said in a statement.
The video went viral on social media websites after students discovered it online before the start of the 2012 school year.
The teacher remained on forced leave while the Education Department investigated, as some staff reportedly refused to work with him and parents reportedly threatened to withdraw their children from the school if he returned.
The teacher’s girlfriend had earlier hit out at critics on Facebook.
"Thanks to everyone who has been supportive at this time, it is very much appreciated," she posted recently.
"And to all those juvenile, no-life-of-your-own gossip whores who have turned a hard situation into a living hell for a couple of kind hearted, loving people, just wait for karma to catch up and kick you in the face!"
