The head of a Queensland Islamic school is blasting Senator Pauline Hanson and media demagogues for the severed pig's head left in front of the school for children to find.

"The shock jocks and politicians are mainstream demonizing Muslims and Islam," said Ali Kadri, acting chairman of the Islamic College of Brisbane in Karawatha, QLD.  "If ISIS is going to do propaganda and target Muslims to make them do stupid actions, I think people like.. Pauline Hanson are doing the same thing," he added, "They're the same kind of hate crimes.  They have to take responsibility for what they say."

Hanson's office did not comment.

Early on Wednesday morning, someone placed the pig's head in a bag marked with a nazi swastika outside the school's front gate.  Staff removed the disgusting mess before students arrived. 

"They're worried because, while it's a minor thing, there are really young kids who go to that school, because it goes from Prep to year 12," said Mr. Kadri.

CCTV cameras caught four young morons in a Subaru WRX at the scene, and the partial ID plate has been passed on to investigators.

Prominent identity Yassmin Abdel-Magied attended the primary school as a child.  She expressed her revulsion over the attack over Twitter.

"I'm just so sorry," she said, "I'm so so sorry we have to live in a world where kids can't go to school in Australia without being shamed and threatened."
