The parents of students at Woodberry Public School in Woodberry, north of Sydney, said they were shocked when they spotted the provocatively shaped candies at a Mother's Day event at the school Friday, The (Sydney) Daily Telegraph reported.
"I had to do a double-take," said Cassandra Lacey, whose two sons attend the school. "Every single chocolate was to do with sex. This was in the school hall, on the school grounds and in school time."
A Department of Education and Communities spokesman said the chocolates were not provided by school officials.
"The school says that the gifts were prepared by parents, for parents, and the school had no knowledge of them until some of the mothers complained," he said.
School council President Jenny Gray said the official responsible for the chocolates has resigned and the Federation of P&C Associations has been called in.
