Sydney teacher charged over child porn

A NSW Catholic primary school teacher has been charged over child porn in an international sting.

US authorities tracked the 58-year-old male teacher's activity to a computer at a home in Auburn, in Sydney's west, and local sex crimes squad officers arrested him on Tuesday.

He faces two charges of using a carriage service for child pornography material and four counts of possession of child abuse material.

He was granted conditional bail to appear before Burwood Local Court on October 21.
