Population justification: A survey in 1999 revealled that abundance was similar to that found in a survey in 1991, from which a population of c.6,000 mature individuals was estimated based on the frequency of observation over northern South Australia. This estimate is still thought to be appropriate (L. Pedler in litt. 2007), and roughly equates to 9,000 individuals in total.

Trend justification: No decline was detected when survey results from 1991 and 1999 were compared, and the population was regarded as stable (Garnett and Crowley 2000). A survey of Mt Lyndhurst in March 2007 indicated that the population there remains stable (Pedler et al. 2007).
