According to researcher Roscoe Turner, “the girls who came into the care of the sisters often had problems that could not be resolved in their normal environment and needed the loving care of others to restore their sense of self-worth.”
Originally, the first sisters and girls stayed in the manor that was built by the previous owner. However, soon after the religious order constructed a training and working block for clothes making and cooking skills, plus a 20-30 girl dormitory. More constructions for the growing number of girls were built in the 1960’s and 1970’s, including another dormitory and sports facilities such as a gymnasium, tennis courts and a swimming pool.
Apparently the last building built at Marycrest was the large convent near the entrance (first two images), for the growing number of sisters at the facility, whose numbers allegedly reached up to fifty. At its peak in the 1970’s, Marycrest allegedly housed up to 70 girls. The borstal finally shut it’s doors around 1983, due to changes regarding institutional counselling and care and the declining number of sisters.
I managed to contact the owner of the property in Australia, in the vague hope of gaining permission to document the site. He was unsurprisingly very hostile to my idea- probably because the site is an absolute disgrace- and gave me his answer as a definitive no.
