A Launceston Aquatic cleaner recorded a young boy getting changed in a cubicle the Launceston Magistrates Court has heard.
Simon Patrick Harvey, 36, of Mayfield, pleaded guilty this morning to one count of making a video recording in breach of privacy.
Police prosecutor Konrad Plachta said Harvey positioned a mobile phone under the cubicle and filmed a 10-year-old boy getting changed.
The boy saw the phone and left the cubicle reporting the incident to his mother.
In an interview with police, Harvey said he thought a woman was in the cubicle.
He stopped filming and deleted the recording when he realised it was a child.
Mr Plachta did not oppose Magistrate Simon Brown sentencing Harvey on the belief that he intended to film a woman.
The matter was adjourned to June 27.
Launceston City Council, which operates the centre, issued a statement saying Harvey no longer worked for the contractor that cleaned the facility.
"The individual in question was employed by the Launceston Aquatic contractor for a total of less than six weeks,'' council general Robert Dobrzynsk said.
