Population justification: There have been three reports of large concentrations of Princess Parrots in the last fifty years: up to 300 on Canning Stock Route in the early 1990s (Carter 1993), a maximum of 172 at the best-known breeding event, during 2010 on the eastern edge of their range, a region which was also occupied in 1894 (Pavey et al. 2014), and a flock of at least 110 at Newhaven Reserve in winter 2012 (C. Pavey unpublished). In the last decade, however, there have been sightings over a large range in the Great Victoria, Little Sandy and Gibson Deserts both before and during the most recent documented breeding event suggesting a population at least ten times that number, so the maximum population size is suspected to be c.10,000 mature individuals but this requires confirmation. The population is thought to vary substantially in response to conditions, and is suspected to number fewer than 1,000 when at minimum (Pavey et al. 2021).

Trend justification: Earlier suggestions that the species is declining (Reid and Fleming 1992) were made before the 2010 breeding event in central Australia and the extreme variability in records across the range confounds any change in distribution. As a result the population is thought to be stable.
