The church contains many relics and memorials associated with the wreck of the Quetta in 1890, with other Torres Strait shipwrecks, and with persons closely associated with the work of the church. Quetta "relics" include a lifebelt, washed ashore on Albany Island; and a porthole, thickly encrusted with coral growth, and the Quetta's stern riding light, both of which were salvaged from the wreck in 1906. A slab of timber on which the diocesan arms is carved and painted, the top of a small credence table, and a palm stand to the memory of Edgar Dawson, are made from Quetta timbers. In addition to the relics from the ship, many of the church furnishings are memorials given by families and friends of Quetta passengers, including a brass offeratory plate, lectern and plaques (including a memorial plaque to two young girls from the Lacy family, one of whom survived the wreck, and one of whom drowned); and a window in memory of Alexander and Louisa Archer, who drowned in the wreck. There is a framed early photograph of the Quetta, and a 1911 plaque with the inscription:This Cathedral was erected TO THE GLORY OF GOD and in memory of those lost in the wreck of the BI SS QUETTA 3484 tons which about 9.14pm on FRIDAY 28TH FEB. 1890, struck an unchartered rock in the ADOLPHUS CHANNEL whilst outbound from Brisbane to London, and although in calm waters and bright moonlight, sank within three minutes with the loss of 133 lives out of a total of 293 on board.
