This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
|Previously published Red List assessments:||
|Range Description:||Strepera graculina is endemic to eastern Australia and its offshore islands (del Hoyo et al. 2009). The subspecies ashbyi of south-west Victoria became extinct through hybridisation during the 20th century (Garnett et al. 2011).|

|Extreme fluctuations in area of occupancy (AOO):||No|
|Estimated extent of occurrence (EOO) - km2:||1580000|
|Continuing decline in extent of occurrence (EOO):||Unknown|
|Extreme fluctuations in extent of occurrence (EOO):||No|
|Continuing decline in number of locations:||Unknown|

|Population:||The global population size has not been quantified, but the species is described as abundant (Morcombe 2000).
Trend Justification: Population increases have been noted in urban areas probably owing to the increased food supply available (Higgins et al. 2006).
|Current Population Trend:||Increasing|
