The General Post Office (GPO) in Brisbane, Queensland, Australia, is a heritage-listed building located at 261 Queen Street.

Initially, postal services operated from a small convict-era building, which was inconveniently distant from the telegraph office.

The Postmaster-General selected a centrally located half-hectare site for the new post office.

[1] The building previously located at the Queen Street site, which once housed women convicts, was demolished in 1871.

That same year, a second wing constructed by John Petrie was completed, allowing the telegraph office to relocate to the GPO, much to the satisfaction of business customers The building features deep verandahs and high ceilings.
