The 1950s heralded a boom period for the City of Bundaberg, with the population growing by one third from 15,926 in 1947 to 21, 235 in 1957. In 1958 a new larger modern Court House was constructed in Quay Street, adjacent to the 1900 Police Station building and facing Anzac park situated on the banks of the Burnett River. At this time the original court house was remodelled to accommodate the Police Service.
