It was to be a huge and ambitious structure with a wide nave and aisle and three towers. Polding did not live to see it in use as he died in 1877. Five years later, on 8 September 1882, his successor, Archbishop Vaughan, presided at the dedication Mass. Archbishop Vaughan gave the peal of bells which were rung for the first time on that day. Vaughan died while in England in 1883. The cathedral's builder (for this stage) was John Young, who also built a large sandstone house in the Gothic Revival style, known as "The Abbey", in Annandale, New South Wales. But St Mary's was still far from finished, the work proceeding under Cardinal Moran. In 1913 Archbishop Kelly laid the foundation stone for the nave, which continued under the architects Hennessy, Hennessy and Co. In 1928 Kelly dedicated the nave in time for the commencement of the 29th International Eucharistic Congress. A slight difference of colour and texture of the sandstone on the internal walls marks the division between the first and second stage of building.

The decoration and enrichment of the cathedral continued with the remains of Archbishop Vaughan being returned to Sydney and buried within the Chapel of the Irish Saints. The richly decorated crypt which enshrines the bodies of many of the early priests and bishops was not completed until 1961 when it was dedicated by Cardinal Gilroy. For many years the two squared-off towers of the façade gave a disappointing appearance to an otherwise-elegant building. It was from time to time suggested pinnacles should be put up to match the central tower as it appeared plain that William Wardell's proposed spires would never be built. But with the assistance of a grant from the Government to mark the new millennium, the spires were eventually built in 2000. Since 2000 In 2008, St Mary's Cathedral became the focus of World Youth Day 2008 and was visited by Pope Benedict XVI who, in his homily on 19 July, made the historic full apology for child sex abuse by Catholic priests in Australia, of whom 107 have been committed by the courts.
