The Tasmanian Emu is considered by many to have been a subspecies of the extant species of Emu, D. novaehollandiae.  But Tasmania has been isolated from mainland Australia since the Miocene, so it is more than likely that this flightless bird was a full species.
It went extinct at the end of the nineteenth century.
