A teacher has landed in hot water after assigning her class to plan a terrorist attack that would kill as many innocent people as possible.
Students at Kalgoorlie-Boulder Community School in Western Australia were given the assignment in a class on contemporary conflict.
They were asked to pretend they were terrorists making a political statement by releasing a chemical or biological agent on "an unsuspecting Australian community".
The task included choosing the best time to attack and explaining their choice of victims and what effects the attack would have on a human body.
"Your goal is to kill the most innocent civilians in order to get your message across," the assignment read.
Principal Terry Martino said he withdrew the assignment as soon as he heard of it.
"The teacher, who is relatively inexperienced, made a well-intentioned but misguided attempt to engage the students," said Mr Martino.
Student Sarah Gilbert (15), whose mother lost a relative in the 2002 Bali bombings, was horrified.
