A body found at the construction site of Queensland's new government headquarters has been identified as that of a French tourist.

Police say it appears the 21-year-old trespassed onto the 1 William Street property in Brisbane's CBD and believe his death may have been the result of a misadventure.

Construction workers found his body at the bottom of a crane and notified police just before 6am on Monday.

It's believed he fell to his death from a significant height.

Police are preparing a report for the coroner.
