Population justification: Its population could possibly number c.100,000 birds, including c.50,000 mature individuals. However, there are effectively no data to support this (S. Garnett in litt. 2007, J. Woinarski in litt. 2007).

Trend justification: The species may historically have disappeared from half of its range, particularly near the McArthur River region, where it was last recorded in 1913 (Garnett and Crowley 2000), however no recent declines have been reported even though the population is sparse and scattered, and population declines in the last three generations (11 years) are considered unlikely (Garnett et al. 2011). The population trend is therefore suspected to be stable.
