With the repetition of forms and the strongly vertical lines characteristic of Perpendicular Gothic, Blacket succeeded in creating a building which, despite its small size, is nevertheless imposing and of harmonious proportions. The western front with its layered decoration is a majestic composition, based loosely on that of York Minster. The strongly projecting rectangular buttresses, which transform by stages into lofty octagonally-sectioned pinnacles, and the complex molding around the portals casts varied shadows in the bright Australian sunlight. Kinsela describes it as "“a grand façade with superb towers…Covered with a profusion of ornanament, blind traceries and tiny attached pinnacles, in a light-hearted yet elegant manner.”"
