• In captivity it has lived about 8–10 years.
• The young spends its first months in the pouch.

The dusky pademelon has a typical lifespan of from 5 to 9 years, with a maximum recorded lifespan of 9 years and 5 months, although the theoretical lifespan ranges from 4 years and 6 months to 8 years and 8 months. The species reaches sexual maturity from 1 year to 1 year and 10 months. The young’s eyes open between 4 months and 5 months and 1 week of age; during this time, the embryo develops inside the mother for a very short period before premature birth. The juvenile stage lasts from 1 to 7 months, during which the young remains in the mother's pouch and is fed with her milk. Following this, the stage of rapid growth occurs, when the young leaves the pouch but remains near its mother, learning how to find food, lasting from 7 months to 1 year and 3 months. The adult stage begins at 1 year and 3 months and lasts until 9 years, during which the adult dusky pademelon is capable of reproduction and independently obtains food.
