Trinity College, Perth

Trinity College is a Catholic secondary school for boys in Perth, Western Australia. It was founded by the Christian Brothers in 1962, and various Brothers continued to be present at the school until 2005, when the last, Br Rob Callen, left the school's Campus Ministry.

Its predecessor, Christian Brothers College (CBC) was founded in 1894 by the Congregation of Christian Brothers with its main campus in St Georges Terrace, Perth. A nearby school, St Patricks was also operated by the College. It served both boarders and day students.

In 1938, St Patricks closed with boarders and some of the day students transferred to the newly established Christian Brothers Aquinas College in Manning.

In 1960, the Perth City Council purchased the CBC property on the site of the current Duxton Hotel for £267,000 to allow for the widening of St Georges Terrace and the construction of a new hotel in time for the 1962 British Empire and Commonwealth Games. The Chevron-Hilton Hotel Group which had committed to the development, ran into difficulties and the school buildings remained until about 1962 after which they were demolished. The site stayed vacant for several years until an office building for the Australian Taxation Office was built there several years later.

The council provided a 5.7 hectare (14 acre) site on reclaimed land in East Perth on the banks of the Swan River, and adjacent to the WACA Ground and The Causeway. The new college was renamed Trinity College and opened in time for the start of the school year in 1962 with space for 830 day boys. The official opening was held on 25 March 1962.

In 1968 Trinity joined the Public Schools Association.

After the East Perth move, lay teachers gradually replaced brothers who had taught there previously. In 1994 the first lay principal was appointed.
