Learning support co-ordinator Kelly Johnson said students taking part in the life skills program had created the musical garden, which was unveiled last Friday.
But when they returned to school on Monday, Mrs Johnson said they found it had been wrecked by vandals, most likely during the evening of September 20.
‘It is such a shame,’ she said. ‘The students with special needs and their friends have worked on this project for a term, not to mention the education assistants, parent helpers and other staff members.
‘We have had parents working with our students with special needs as well as some of our mainstream students to construct the instruments.’
Mrs Johnson said the instruments, which included a giant thong-o-phone, metal |xylophone and drum, were made with recycled materials from Tamala Park.
She said they had hoped to inspire the wider community to create similar musical gardens and would rebuild.
