The assessment reports one recent state record: a male caught in a pitfall trap at Sturt National Park in September 2008. This is a capture record, not a study of daily behavior or population size in the state.
Queensland surveys recorded it in Triodia hummock grassland, savanna woodland, shrubland, and grassland. Abundance was associated with ground cover, and it was more numerous in pastures with a high cover of native hummock grasses.
An extinction-risk assessment has not been added yet.
