at a cost of £460 by Charles Richardson and installed in 1911. By the 1970s the organ was becoming unreliable and the college organist at the time, Peter Meyer, contracted Arthur Jones to rebuild it in 1976. Although the first dayboys were not officially admitted until 1923, there was a small group of pupils who were permitted to attend the college as dayboys. In fact, up until the 1960s dayboys remained relatively small in number and Riverview was mainly for boarders. In the lead up to the 2003 Iraq War, the three school captains wrote a letter to the Prime Minister of Australia, John Howard, calling for a withdrawal of Australian troops from the Persian Gulf and for a non-military solution. They told Howard a poll of 574 students at the college showed 75 per cent were against Australian military participation in Iraq, regardless of the United Nations’ position. During February 2005, students sang for Pope John Paul II outside his hospital in Rome as part of the 2005 Pilgrimage of Hope. The students had previously met the Anglican Archbishop of Canterbury, Rowan Williams, meditated in Assisi and worked the streets and orphanages of Calcutta with Mother Teresa's Missionaries of Charity. The year 2005 saw Riverview play host to a series of 125th anniversary celebrations culminating in a whole school Mass at St Mary's Cathedral, Sydney, on the feast of Ignatius of Loyola, 31 July. Motto The school motto, Quantum Potes Tantum Aude ("Dare as much as you can, for God and for Man"), was introduced by the rector-headmaster, Thomas Gartlan SJ, in 1906.

The motto is taken from a song of Saint Thomas Aquinas (1227–1274) entitled Lauda Sion Salvatorem ('Praise, O Sion, Praise Thy Saviour'). The next line after Quantum Potes Tantum Aude is Quia Maior Omni Laude, which, together, translates to "As much as you can do, so much dare to do, because He is above all praise".

This stands for Ad Maiorem Dei Gloriam which means "To the Greater Glory
