Ex-Perth College chaplain Matthew O'Meara loses child porn conviction appeal Matthew David O'Meara, the former Perth College chaplain, has lost an appeal against his child pornography conviction. A FORMER Perth girls' school chaplain found guilty of child pornography offences has lost an appeal against his conviction. Matthew David O'Meara was convicted after a three-week trial in March of four child pornography charges related to hundreds of explicit images and video files found on two thumb drives. The former chaplain of Perth College was sentenced to 15 months' imprisonment but appealed the conviction, arguing it was a miscarriage of justice. Three Court of Appeal judges unanimously agreed on Wednesday that the grounds of the appeal could not succeed and Justice Stephen Hall said the appeal must be dismissed. O'Meara will be eligible for parole in mid-November.
