[1] Francis Drummond Greville Stanley emigrated to Queensland in 1861 and worked as an architect for the Lands Department before entering private practice.

[1] In 1867, Post Master General, Thomas Murray-Prior reported to Parliament that complaints were being received concerning the lack of [postal] facilities at Gympie.

Booth ran the post office from a shop in Mary Street, and the service rapidly expanded in the first two years.

However the gold rush continued to bring an influx of people to Gympie and the postal service developed accordingly, rendering the second post office building inadequate in a very short time.

[1] A portion of land was set aside for a new post office on the corner of Duke and Channon Streets on what was then known as Commissioner's Hill.

Due to its remoteness from the centre of the town, this location received strong protest from the residents of Gympie and a petition of five hundred signatures was sent to the Minister of Works.

The contract was signed on August 23, 1878, however, the building was not completed in the specified time due to bad weather and a lack of skilled labour.

The remaining space was used by the post master as his residence and included most of the first floor and a ground level sitting room at the rear of the main building.

[1] In February 2019, a local firm Corbet Johns Builders purchased the building with the intention to restore it and use it as their office.

[2] The Gympie Post Office is located at the intersection of Channon and Duke Streets and is a substantial two-storeyed masonry building.

It is a dominant landmark in the streetscape and together with the Lands Office, Police Station and Court House, forms a precinct of Government buildings.

Other decorative features include keystones at the centre of each arch, small brackets below the first floor verandah and cast iron balustrading.

[1] The elevation facing Duke Street is a continuation of the design of the end sections, with a slightly projecting central bay capped with a triangular pediment.

[1] Internally, much of the partitioning from the building's use as a post office has been removed, resulting in an open space on the ground level.

[1] The first floor comprises a corridor which runs between the staircases at the rear of the building and offices divided by new partitioning at the front.

It is also of aesthetic significance for its design qualities and detailing including cast iron balustrading and internal joinery elements.
