The Old Windmill, the oldest building in the state of Queensland, sits in Wickham Park in Brisbane. The mill was built by exiled convicts in 1824 to grind grain - wheat and corn. In December 1828 it was given wind-powered wings. After the murder of two members of a geological party near Mount Lindsay in May 1840, three local aborigines were charged with the offence. In July 1841, two of them were hanged from the rung of the upper window of the mill.
In January 1862, the Old Windmill Windmill became the first home for the Queensland Museum. It was later used as a signal tower and today serves as a weather observation station.

From 1922 to 1926, the mill was a meeting place for members of the Institute of Institute of Radio Engineers, where they conducted their experiments, in particular testing the the transmission of medium wave AM radio broadcasts. The building was ideally suited for this purpose, as it had a panoramic view from Moreton Bay in the east to the Darling Hills. in the east to the hills of the Darling Downs in the west. Next to the mill, a 45 metre mast and a 24 metre antenna between the mill and the mast - in those days it was the most impressive structure in Queensland. In the 1930s and 40s the building was used to broadcast the first television programmes.
