North Quay, Brisbane in the context of Spring Hill, Queensland

The Treasury Building, previously known as the New Public Offices, is a heritage-listed former public administration building located at 21 Queen Street in Brisbane, and is the largest 19th-century government building in Australia by gross floor area. It was built from 1886 to 1928 for the Queensland Government. On 21 October 1992 the Italian Renaissance building was added to the Queensland Heritage Register.

The building is located at North Quay, near the northern end of Victoria Bridge. Although officially fronting on Queen Street, the building occupies an entire city block surrounded by Queen Street, George Street, Elizabeth Street and William Street. The Elizabeth Street frontage is opposite the Queens Gardens. In the 1890s and early 1900s the imposing Treasury Building served as a symbol of self-government and as a focus for celebratory and patriotic displays.

Brisbane (/ˈbrɪzbən/ BRIZ-bən; Turrbal/Yagara: Meanjin, Meaanjin, Maganjin or Magandjin) is the capital and largest city of the state of Queensland and the third-most populous city in Australia, with a population of approximately 2.8 million. Brisbane lies at the centre of South East Queensland and is located roughly in the midpoint of Australia's eastern coastline. It is an urban agglomeration with a population of over 4 million. The central business district is situated within a peninsula of the Brisbane River about 15 km (9 mi) from its mouth at Moreton Bay. Greater Brisbane sprawls over the hilly floodplain of the Brisbane River Valley between Pacific Ocean and the Taylor and D'Aguilar mountain ranges, encompassing several local government areas, most centrally the City of Brisbane, the most populous local government area in Australia. The demonym of Brisbane is Brisbanite or Brisbaner.

The Moreton Bay penal settlement was founded in 1824 at Redcliffe as a place for secondary offenders from the Sydney colony, but in May 1825 moved to North Quay on the banks of the Brisbane River, so named for the Governor of New South Wales Sir Thomas Brisbane. German Lutherans established the first free settlement of Zion Hill at Nundah in 1838, and in 1859 Brisbane was chosen as Queensland's capital when the state separated from New South Wales. During World War II, the Allied command in the South West Pacific was based in the city, along with the headquarters for General Douglas MacArthur of the United States Army.

The Victoria Bridge is a bus and pedestrian bridge over the Brisbane River. The current bridge, opened in 1969, is the third permanent crossing erected at this location. Since 24 January 2021, the bridge has been closed to general traffic, and now carries buses, pedestrians and cyclists only.

The Victoria Bridge, the Brisbane River's first road crossing has had a long and interesting history. Since 1865 there have been several versions of the bridge built to connect South Brisbane (near the South Bank Parklands and Queensland Cultural Centre) to the Brisbane central business district (CBD) at North Quay. Half of the road space on the bridge is now given over to the South East Busway. In the 2006 Brisbane City Centre Draft Masterplan, a new crossing immediately adjacent to the Victoria Bridge, tentatively named the Adelaide Street Bridge was recommended for a feasibility study.

The William Jolly Bridge is a heritage-listed road bridge over the Brisbane River between North Quay in the Brisbane central business district and Grey Street in South Brisbane, within City of Brisbane, Queensland, Australia. It was designed by Harding Frew and built from 1928 to 1932 by MR Hornibrook.

The style of the bridge's design is Art Deco, which was popular at the time. MR Hornibrook company built the bridge that consists of two piers that were built in the river and two pylons on the river banks, which support three graceful arches. The rainbow arch type, as it was described, was claimed to be the first of its type in Australia. It is a steel frame arch bridge with an unusual concrete veneer, treated to make it appear like "light-coloured porphyry".
