A former Knox Grammar teacher has been found guilty of grooming a 15-year-old on a dating app.

Gulson had allegedly messaged the minor, who used a fake name, on the dating app Grindr, the court was previously told.

The grooming occurred over a 48-hour period in August 2024, when Gulson was chatting with the complainant who he knew was 15 years old and in Year 9, the court was told.

During the exchange, which Gulson was engaged in while he was at home marking his student’s assignments, the teacher asked the teenager: “Do you find it hot your as old as some of my students?”

Gulson was quiet, and had no comment for media following the verdict as he walked out of court on Tuesday.

He pleaded not guiltyto the lone charge and faced a three-day hearing in the Downing Centre Local Court last September.

Following the hearing, magistrate Hugh Donnelly on Tuesday found the former teacher guilty.

The charge carries a maximum of 12 years imprisonment in NSW.

Gulson’s employment with Knox Grammar School was terminated in September after the allegations came to light.

He will be sentenced on March 20.

His conditional bail is to continue until sentencing.

More to come.
