Population justification: Garnett et al. (2011) estimate that the current population probably contains around 2,000 mature individuals and is declining. It is placed in the band 1,000-2,499 mature individuals.

Trend justification: A population viability analysis model predicted that the population will decline by an average of 87% (79-95%) over three generations (12-18 years) (Heinsohn et al. 2015). The paper suggests that the most likely scenario is that where the population is predicted to decrease by 94.7% in three generations, owing to predation by Sugar Gliders. The models represent a conservative, best-case scenario - other likely causes of mortality such as habitat loss and collisions with man-made structures were not included. Predation by Sugar Gliders is likely to be so severe that even successful breeding on offshore islands free of the predator will be insufficient to prevent an overall population decline.
