17-year-old Tullawong State High School school captain Liam Keegan was killed on Tuesday, March 23, at about 7pm after being electrocuted in his home on Darley Road, Upper Caboolture.

The father of the high school student has since revealed he was working on a woodworking project in the family’s shed, using electrical fractal burning to decorate the project.

Liam’s father Sean Keegan said he was speaking out to warn others against the dangers of using the technique.

“It is very popular all over the internet, but looking into it now it is very dangerous,” Mr Keegan told The Courier Mail.

Fractal burning is done by using a high voltage electrical source to burn branch-like designs into wood.

Police, paramedics and Queensland Fire and Emergency Services responded to the incident, as well as Workplace Health and Safety investigators and several Energex crews, The Courier Mail reports.

A workplace Health and Safety spokesperson confirmed that the Electrical Safety Office is investigating the cause of the incident, and has not yet confirmed how the tragedy occurred.

Witnesses reported hearing a loud bang, and another distressing screaming before responders arrived.

Liam Keegan has been described in an outpouring of tributes to the young man as someone who touched the lives of many.

Tullawong State High School principal Kiah Lanham said the school community was deeply saddened by his sudden and tragic passing.

Ms Lanham described Liam as a popular and talented young person who will be greatly missed by all of his friends and teachers.

“Our thoughts and sincere sympathies go out to his family, friends and loved ones during this difficult time,” Ms Lanham said.
