The Perth Town Hall, situated on the corner of Hay and Barrack streets in Perth, Western Australia, is the only town hall built by convicts in Australia. Upon completion it was the tallest structure in Perth.

Hay Street is a major road through the central business district of Perth, Western Australia and adjacent suburbs. The street was named after Robert William Hay, the Permanent Under Secretary for Colonies. Sections of the road were called Howick Street and Twiss Street until 1897. One block in the central business section is now a pedestrian mall with extremely limited vehicular traffic, so that it is necessary to make a significant detour in order to drive the entire length of Hay Street.
