Ayr Post Office is a heritage-listed post office at 155 Queen Street, Ayr, Shire of Burdekin, Queensland, Australia. It was designed by the Commonwealth Department of Interior and was built in 1936. It was added to the Australian Commonwealth Heritage List on 22 August 2012. History European graziers raising sheep and cattle in the interior of North Queensland settled the Burdekin River district in the 1860s. The first commercial crop of sugar was produced in 1881 and assured the manufacturing strength of the region. The township of Ayr was laid out in 1882, intended as the centre for the region. Reserves were set aside for administrative and government purposes, including the court house, police station and post and telegraph office. In 1884, James Palmer constructed the first post office and residence to a design by John James Clark, then the Colonial Government Architect in Queensland's Public Works Office. The first postmaster was Thomas Bishop who lived in the separate quarters neighbouring the post office on the south side. In the 1930s, the earlier post office and residence were replaced by the current building, after the Burdekin Shire Chairman led a deputation to the Australian Postmaster General's Office requesting a more adequate building. On 21 April 1934, the Prime Minister Joseph Lyons announced that plans for the new Ayr Post Office had been completed and was expected to cost about to construct. Ayr Post Office was designed by the Commonwealth Department of Interior, which took over responsibility for constructing post offices in Queensland in 1921–23. The building occupied the site of the previous post office. Separate quarters were again provided on the south side (but have since been removed). It was completed in 1936 Description Ayr Post Office is at 155 Queen Street, corner Young Street (formerly Bey Street), Ayr, comprising the whole of Lot 1 RP742482. Queen Street is Ayr's main street and part of the Bruce Highway. It is part of a civic precinct with the community centre, courts and police station, the council offices and nearby Country Women's Association building. A war memorial and clock lantern on the adjacent traffic roundabout enhances the setting to the building, including the corner landmark intersection. Further north, Queen Street has been upgraded including the erection of a steel-framed shade structure along the length of the median strip. The street is flanked by single storey commercial buildings and shops. The post office
