Sunnyside estate (now Morning Star Estate) was originally purchased by Londoner Francis Alfred Gillett in 1865 a short time after he arrived in the colony in 1853. Gillett designed the Sunnyside mansion sometime around 1867–1870. In 1932 the property was purchased, with funds from a bequest, by the Catholic Church and became known as Morning Star Boys' Home. The boys’ home was developed into a country-training centre for delinquent boys, giving them exposure to the benefits of rural life. The boys later became involved in an extensive building program, which led to further developments of the property. Despite this, the mansion remained the dominant architectural feature of the property.
