 Although the Sisters of St. Joseph operated eight primary schools in the Diocese of Port Augusta , it was without a Catholic high school — boarding or otherwise . Accordingly , while he was staying in Sydney for his consecration , O 'Reily sought to establish a convent for the Sydney @-@ based Sisters of the Good Samaritan in Port Pirie . At the bishop 's expense , the order 's Mother @-@ General spent two months in Port Pirie , and once she had found appropriate living quarters , a school was established , teaching over 100 students . A convent for the sisters was completed in 1890 on the same block as the school .
