Commissariat Store Museum

The Commissariat Store Museum is a heritage-listed museum housed in the 1828-1829 convict-built Commissariat Store at 115 William Street, Brisbane City, Queensland. Operated by the Royal Historical Society of Queensland, it is the oldest occupied building in Queensland and one of two surviving buildings from the Moreton Bay penal settlement. The museum displays archaeological artefacts, convict-era exhibits and Queensland history collections within the original stone and brick structure near the Brisbane River.

Visitors can expect to explore a two-storey Georgian convict-built stone and brick building on the Brisbane River at William Street. Inside are permanent and temporary exhibitions on convict history, early Brisbane and Queensland history, with archaeological artefacts, documents, photographs and objects from the Royal Historical Society of Queensland collection. Guided tours explain the building's construction, penal settlement use and later government store functions. The setting is in the Brisbane CBD adjacent to the City Botanic Gardens and Queens Wharf precinct.

Built 1828-1829 by convict labour as the Commissariat Store for the Moreton Bay penal settlement to store government supplies and provisions. It is the oldest occupied building in Queensland and one of two surviving convict-built structures from the penal settlement period. Later used as government stores, immigration depot and state government offices before becoming the headquarters and museum of the Royal Historical Society of Queensland.

Represents early convict settlement and colonial administration in Queensland and houses the collections of the Royal Historical Society of Queensland, founded in 1913. The building is listed on the Queensland Heritage Register and serves as a centre for Queensland history research, education and community heritage interpretation.
