Holy Cross College is an independent Roman Catholic secondary day school for boys, located in the Sydney suburb of Ryde, New South Wales, Australia.

[3] In 1808, Bishop Daniel Delany established in Ireland the Congregation of the Brothers of St Patrick and sought to have the youth of his native land instructed in the principles and lifestyle of the Gospels.

[7][8] The great sandstone edifice which is now a landmark of the district gradually rose on the heights above the Parramatta River.

The Crest was designed in the early 1900s, and was installed in a stained glass window of the Oratory in the Monastery building.

The Crest features the Waratah and Shamrock entwined, symbolising the shared Patrician Apostolate of Australia and Ireland.
