Population justification: The total population is estimated to number c.40,000 individuals, based on the expert opinion of the members of the Carnaby’s Cockatoo Recovery Team members.  No detailed survey of the population has been conducted to provide a more accurate figure (P Mawson in litt. 2016).

Trend justification: Direct counts, numbers of breeding females, a decrease in the area of occupancy and decline in the quality of habitat indicate that this species's abundance has at least halved over the last three generations, and that this decline is likely to continue (Garnett and Crowley 2000; Garnett et al. 2011).
