St Andrew's Cathedral is of historic significance as the place of the first cathedral to be commenced in Australia. It reflects the changing views and attitudes both theological and social within the Diocese of Sydney in the physical changes that have taken place to the building. The collection of furniture, fixtures, artefacts and memorials record the history of the building, the history of the Anglican church in Sydney and key personalities involved in both church and civic life who have been associated with the building, the link between the building and the wider church with relics and items from other churches throughout the world and a tradition in quality of craftsmanship and design which can be seen from the 1860s to the present day. Its place in the development of architectural design and thought in the colony, as a perfect example of the colonial desire to reproduce England in Australia in the mid-nineteenth century which affected the design of many churches to follow in the colony. It is an example of the connection and inter-relationship of Church and State in the Colonial and Victorian periods.
