A substitute teacher with experience in both primary and high schools across Adelaide has been charged with child sexual offenses, prompting concern among parents and school communities.

Families from four educational institutions in Adelaide’s eastern suburbs received notification today about the arrest of the 51-year-old relief teacher, who is accused of committing child sex crimes.

The teacher in question has been associated with at least four schools in the area, specifically Stradbroke School, Marryatville High School, Charles Campbell College, and East Adelaide School.

Parents were informed of the situation through a consistent message conveyed in letters distributed by the principals of the involved schools.

The communication assured parents that, at this point, there is “no evidence” to suggest that any students from the schools are directly involved.

“However, I am concerned … because students may have had contact with the temporary teacher,” it read.

The man has been banned from school sites and engaging in any child-related work while police continue their investigation.

But parents today said they remained worried about their children’ s safety.

“I feel a bit concerning [sic] but it’s good to know, I guess, they’ve acted on it,” parent Christine Lim told 9News.

The man, from Adelaide’s north-eastern suburbs, has been bailed to appear in court in February.
