After leaving school, she joined the Sisters of St Joseph of the Sacred Heart. Sister Irene spent many years teaching in schools in country areas and constantly advocated for country children. After 30 years of teaching in Australian schools and as a Principal, Sister Irene made the difficult decision to leave teaching to serve the poor.
Sister Irene arrived in Peru in 1987 and worked as a missionary for the people of Peru. The people of Peru truly opened their hearts and homes to Irene and then became Irene’s second family.
Despite knowing the risks of ministering in such a troubled region, Sister Irene taught poor children, ran a food kitchen and provided books to help educate poor children. She trained Extraordinary Ministers of Holy Communion, visited parishioners in outlying districts, and distributed Caritas food packages.
On 21 May 1991, armed rebels took over the town and marched the 52-year-old and four local men to the town square. The Shining Path guerrilla group executed Sister Irene in the village of Huasahuasi along with the four villagers. The Maoist group accused them of dispensing ‘American food’ and spreading ‘American ideas’. Local people insisted that Sister Irene was Australian, not American, but the guerrillas did not care.
