Koalas are seasonal breeders, and births take place from the middle of spring through the summer to early autumn, from October to May.
As with all marsupials, the young are born while at the embryonic stage, weighing only 0.5 g (0.02 oz). However, they have relatively well-developed lips, forelimbs, and shoulders, as well as functioning respiratory, digestive, and urinary systems. The joey crawls into its mother's pouch to continue the rest of its development. Unlike most other marsupials, the koala does not clean her pouch.At seven weeks of age, the joey's head grows longer and becomes proportionally large
As the young koala approaches six months, the mother begins to prepare it for its eucalyptus diet by predigesting the leaves, producing a faecal pap that the joey eats from her cloacum.
