Haymarket Post Office, Historic post office in Haymarket, Sydney, Australia

Haymarket Post Office is a five-story building at 633-635 George Street with rectangular portals and windows recessed into arches on the ground floor. The structure displays classical architectural features with carefully proportioned details across its facade.

The Australian Government acquired the land in 1912 under the Lands Acquisition Act, and construction of the building took place between 1927 and 1928 by H. W. Thompson Ltd. The design followed Interwar architectural principles and established a new service hub for the area.

The Chinese Consulate General occupied the second floor from 1932 until 1973, when the consul appears to have closed. From 1944 the engineering section of the Postmaster General's Department moved in from the cramped General Post Office, and by 1946 all floors except the consulate held postal and telegraphic services.

The building no longer operates as a post office, but visitors can find alternative services nearby in the area. World Square Post Shop and Sydney GPO Post Shop provide postal services for anyone who needs them.

The building still preserves its original open-style lift and postal hall from the Interwar period. These functional spaces rarely survive and show how the service operated when it was built.
