Apparently, breeding occurs over most of the year. In the Dawson Valley of central coastal Queensland, females with pouch young were taken from January to March. Near Killarney in southeastern Queensland, three females with pouch young were caught in June, and local residents reported finding pouch young all year. Females in a captive colony at Canberra had large pouch young in February, July, and August, and smaller ones in July, August, and December. The gestation period is 22-24 days.
Litters usually consist of a single offspring, but twins occasionally occur.
The pouch young releases the nipple at 7-8 weeks, vacates the pouch permanently at about 16 weeks, and then remains with the mother for another 7 weeks. Farther to the south the species has disappeared, the last record in Victoria dating 1905. Its decline may have resulted from predation by introduced foxes. The Johns Hopkins University Press.
