Population justification: The 1995-2004 surveys of the species suggest the total population is probably still 10,000-15,000 individuals but that only c.10% of those birds make up the breeding population (P. Mawson in litt. 2004).

Trend justification: It is suspected to be in continuing decline, at an unquantified rate, owing to illegal shooting, competition for nest sites with feral bees, and loss of nesting and feeding habitat, owing to logging (P. Mawson in litt. 2004). The population density is believed to be declining at an unquantified rate (Johnstone et al. 2007). The reporting rate probably declined between the 1977–1981 and 1998–2001 (Olsen et al. 2003) but taxonomic changes in the first Birds Australia Atlas and confusion with other Black-Cockatoos since make comparisons difficult. Given the lack of any recent quantitative data, the rate of decline is inferred from changes in habitat and competition to be >50% in 3 generations (Garnett et al. 2011).
