The West Australian Football Commission and Burley Sekem run competitions to design football jumpers each year, with a record 146 entries from around the State this year.
Teacher Robert Tunney encouraged local students to think about a design, which resulted in Jessi Fernie and Jess Little winning the top prize.
‘We chose to put a piranha on our footy jumper because we wanted to put something on there that started with ‘P’,’ he said.
‘We came up with other names like the Pixies and the Pineapples, but the Piranhas was the name that stuck.’
Mr Tunney said the new jumpers were much needed.
‘Pickering Brook Primary has been using a set of hand-me-down training jumpers that were donated by a local football club years ago,’ he said.
‘The new jumpers look fantastic and are a lot more comfortable to wear compared to the old jumpers.’
Chelsea Randall, from the Swan Districts Football Club, made a presentation to the winning students at a school assembly.
