 Unlike the Decorated Gothic tracery at St Paul's, the Perpendicular Gothic tracery is repetitious in its form.The visual effect of the church is one of harmony and elegance of proportion.Because of the Evangelical nature of this church, there is no figurative decoration, but the east window by James Powell and Sons of Whitefriars, "variegated with flowers and interspersed with texts", cost £200 and is one of the finest non-pictorial windows in Sydney.
