Breeding probably occurs throughout the year. The estrous cycle lasted 31-36 days, and gestation about 30 days. Dominant females had shorter cycles than did subordinates. The single young opens its eyes at about 110 days, leaves the pouch at about 160 days, and is independent at about 175 days. Weaning is much more sudden than in Petrogale.
Sexual maturity is attained in the second year of life.
