The mother of a primary school teacher accused of grooming and indecently assaulting students has leapt to her son's defence saying she pities every male teacher.

Shane Andrew Matthews, 29, allegedly groomed and indecently assaulted three male students at a primary school in Sydney's south-west between 2012 and 2015.

He has taught at Wattle Grove Public School, and started a new role as an assistant principal at Woodland Road Public School at the beginning of this year.

A school newsletter announcing Mr Matthew's departure to start in the new position described him as a "wonderful asset at our school for seven years", and a teacher with "amazing expertise" in creative and practical arts.

"Mr Matthews has also proven to be a very popular teacher with the students in his care, with units of work on Super Heroes legendary," the notice states.

"Mr Matthews has been an engaging member of staff with all of our school community, a great contributor to our school in so many facets and he will be sorely missed."

He was arrested at his Bradbury home on Thursday and charged with with 10 counts of indecently assaulting a person under 16, three counts of grooming or procuring a child and one count of committing an aggravated act of indecency.

With family members at Campbelltown Local Court to support him on Friday, Mr Matthews was unsuccessful in his bid for bail.

Outside the court, Mr Matthews' mother defended him and suggested the claims against her son were unfounded.

"How would you feel if you were a teacher just going to work and doing your job every day?," she said.

"I pity every male teacher that is teaching in a school, from the day they walk into that classroom to the end of their life, wait for a knock on the door," she said.

Police said Child Abuse Squad detectives launched an extensive investigation following reports an 11-year-old male student had been indecently assaulted by Mr Matthews.

Mr Matthews was heavily involved in extra curricular activities, running and co-ordinating performing arts concerts.

He is due to appear in court again via audio visual on October 26.
