Wild adult males utilize home ranges that are separate from those of other males but overlap those of females. The ranges of the latter do overlap to some extent, but the females tend to avoid one another. Home range size averaged about 1.5 ha. Some males are monogamous and others are bigamous. There is some interaction between the sexes all year, but contact peaks just prior to and during the mating season.
Females are polyestrous and have one litter per season.
In New South Wales mating occurs from March to May and births occur from April to June. In Victoria the young usually are born in July and August. Litters contain a single young. It first releases the nipple at about 6 weeks but spends up to 6 months in the pouch and then another 4 months as a dependent nestling. It may sometimes be carried on the back of the mother.
