The construction of the toilet block necessitated the bricking in of a single window in the projecting wing behind it and the creation of a door opening providing access from the offices.
large detached automated telephone exchange building was constructed on the site to the rear of the post office at an unknown date.
A general interior refurbishment for Australia Post included new cabinetry joinery and fittings throughout the main postal hall and installation of a coved perspex canopy over the panelled timber entrance screen, as well as a new kitchenette in the lunch room.
While the fountain was replaced with a granite and bronze memorial surrounded by lawn, the driveway form remains in an approximate state, albeit with asphalt surface and formalised parking bays along both sides.
The rear yard of the post office has been concrete-paved and is accessed from Wellington Street via a concrete driveway along the northern side of the 1960s telephone exchange.
The two storey complex comprises a multiple-pavilion building of rendered brick construction on bluestone base with distinct sections relating to the residence, post office and former court and sub-treasury functions.
The principal elevation is marked by a four-stage clock tower with flagpole, balustraded top, dentilled cornices and slate-louvered paired openings.
To the north of the clock tower is a two-storey wing containing the original post and telegraph office at ground floor level and quarters above.
The wing is screened by a single-storey triple-arcaded porch with balustraded top to the front elevation and non-original verandah and access ramp to the north.
[1] The elevations are encircled by ribbons of superimposed moulded string courses which rise to archivolts where broken by semi-circular arched window heads.
[1] Externally, Maryborough Post Office's ability to demonstrate its original design is exceptionally good with regard to the architectural conception, principle materials and detail despite a small number of alterations and additions.
These changes have been largely confined to the rear of the building with the exception of disabled access ramping, installation of private letter boxes and the construction of a small verandah area to the north elevation.
Such works include the installation of floor linings, replacement ceilings, mechanical ducting, joinery, false partitions, lighting and over painting of timber components.
For instance, the main postal hall retains its double height volume and clerestory highlights, but has been diminished in aesthetic terms by the installation of standardised slat wall joinery and counters.
While the separate components are conceived as distinct units, they are unified by the complex composition, arcaded facade, applied pattern of fenestration and restrained decoration.
Stylistically, Maryborough Post Office is an impressive Italianate palazzo design which fuses numerous mid-Victorian modes and an asymmetrical composition with restrained detail.
While the composition of the post office complex is seemingly devoid of lavish decoration, it gains its aesthetic weight from a finely composed asymmetrical design and exceptionally well-handled meshing of integrated, yet distinct, functions.
The complex as a whole, together with the adjoining public buildings sited around McLandress Square, also maintains a high level of integrity and legibility with regard to its urban planning attributes.
Maryborough Post Office has been a key and prominent component of the historic townscape for 130 years and is a widely known and valued symbol which is identified with the town's origin and nineteenth century prosperity.
