upgraded. Condition Externally and internally the building is in sound condition, well maintained and with no major defects visible. Heritage listing The significant components of Cooroy Post Office include the main 1913 post office building, but do not include later additions such as the public verandahs on the southern side, disabled access ramp, the single-storey flat-roofed addition to the north of the main office area and the 1960s telephone exchange on the east. The cast iron pillar posting box marked "JS Engineering Co., Brisbane", located at the street corner of the site, is object of significant interest, but it is not known if the pillar box is actually located on Australia Post property (and hence not eligible for inclusion on the Commonwealth Heritage List). Cooroy Post Office was listed on the Australian Commonwealth Heritage List on 22 August 2012 having satisfied the following criteria. Criterion A: Processes Cooroy Post Office, opened in 1913 and built to a design by the Queensland Government Architect Office under AB Brady, has some historical value as a post office remaining in continuous operation since the early twentieth century. This value, however, is enhanced through the post office being one of a limited number of generally modestly-scaled timber post offices still in operation. It is also an extension of contemporary progressive residential work in Queensland and one of the few examples of this development remaining as an operating post office. Although alterations to the building over a long period have had some impac on its heritage value, it remains significant at a local level. Criterion D: Characteristic values Cooroy Post Office is an example of: a post and telegraph office (second generation typology 1870–1929); a Federation period single porch and gable timber form with integrated exchange; the work of the Queensland Government Architect Office under AB Brady. Typologically, Cooroy Post Office, built in 1913, was constructed towards the close of a second typology of post offices dated 1870 - 1929. These post offices generally incorporated a separate component for the telegraph functions in addition to a postmaster's residential quarters. In this instance, however, there was no accommodation for a residence. In the state context, this particular grouping of functions is considered as a descriptor of a post office type known as T18 (Single Porch, Gable and Lantern example) of which 14 known examples were built throughout Queensland during 1909–1913. Cooroy was constructed towards the end
