Mainly nocturnal. Shelters in burrows (warrens) during the day. Can breed from 4 months of age, at any time of the year. When conditions are good they can produce 5 or more litters a year, with 4 to 5 young in each litter. Their impact is greatest during drought and straight after a bushfire, when food is scarce and they eat whatever they can. They ringbark trees and shrubs, and prevent regeneration by eating seeds and seedlings.
