 The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales.The Walter Burley Griffin Incinerator is of aesthetic significance as it is perhaps the best surviving example of the work of the architect Walter Burley Griffin and his partner Eric Nicholls, who designed a range of similar Municipal Incinerators on behalf of the Reverberatory Incinerator and Engineering Company (RIECo) during the 1930s.It is recognised as one of the finest of Griffin's incinerators, where he explored to the maximum his decorative designs in rendered concrete and rough cut stone faced retaining walls.
