A former Perth high school teacher has been jailed for 18 months for possessing hundreds of photographs and videos of child pornography.
Rodney Westacott was arrested last year as part of a global investigation into child exploitation.
The WA District Court heard on Thursday that Westacott had been collecting child pornography for nine years and had now accepted that he had a sexual interest in children.
Westacott must serve nine months in prison before being eligible for parole.
