Population justification: The breeding population has been estimated at around 2,500 mature individuals (Garnett et al. 2011), roughly equivalent to 3,750 individuals in total.

Trend justification: Historically, there were three confirmed breeding populations: from Coen to Port Stewart where it was last reported in the 1920s, Musgrave-Moorhead River where the population has contracted markedly and continues to decline, and west of Chillagoe where the population persists, but trends have been stable. Overall, the population is currently suspected to be declining (Garnett and Crowley 2000), although the likely rate of decline has not been estimated.
