The bank was formed by an influential group of Queensland squatters, politicians, lawyers and businessmen who were anxious to secure development capital, which was free from overseas or inter-colonial control.

In 1948, it merged with the National Bank of Australasia Ltd.[1] Irvinebank (originally named Gibbs Camp) was established in 1883 as a tin town and the centre of entrepreneur John Moffat's mining empire.

Spurred by profitable silver and tin smelters, the nearby town of Montalbion grew quickly during the 1880s and became an administrative centre.

The architect is unknown and it appears that the Queensland National Bank did not the own the premises, but rented the building as an office and manager's residence from the Irvinebank Mining Co. Ltd.

The Queensland Government Mining Journal of 15 November 1919:464 states that "the company also owns a brick building used as the Q.N.

Builders usually employed the technique where poor quality or undersize timber framing was not readily available, even though the original architects plans may have been for another style of roof.

Several sets of low-waisted six-panel (two timber at the base, the rest is clear glass) French doors with rectangular fanlight and flat arch open onto the balcony.

[1] A set of concrete steps with bullnose edges, leading to a short verandah along the front wall of the building, form the entrance to the lower level.

The entrance on this level is a low waisted four-panel timber French door, with a three-pane rectangular fanlight (two panes of clear glass and one painted) and flat arch.

The door and windows on this level are surrounded by a false quoin effect created by brickwork proud of the main wall face.

A white-painted awning, made from timber palings finished to form a decorative edge, hangs from the balcony and covers windows on two sides of the building.

There is a cut stone wall which extends from the rear corner of the building following the slope of the hill, parallel to the benched pathway between the Bank and the School of Arts which leads up to Loudoun House.

[1] Inspections in January 2004 revealed extensive damage to the internal fabric of the building, including original features.

[1] The building forms an important part of the streetscape of Irvinebank because of its unusual roof design, wrap-around verandah, brick construction and visual accessibility from the main street.

The place has aesthetic significance for its architectural qualities, as well as for its contribution to the streetscape through its form, scale and design, which complement the nearby School of Arts, Loudoun House, and other surviving 19th century buildings.

Irvinebank's frontier setting, nestled amongst the isolated hills of Far North Queensland provides visual context contributing greatly to the aesthetic value of the building.

[1] The place has a special association with the life or work of a particular person, group or organisation of importance in Queensland's history.
