The population expanded with new, wild-born joeys being recorded and survived several drought years in the early 2000s.
Gestation lasts 44 days and joeys of captive bred individuals leave the pouch after 11 months.
A female koala has two teats; the joey attaches itself to one of them and suckles for the rest of its pouch life.
However, after this the blastocyst remains dormant even after the joey has left.
An infant marsupial is known as a joey.
Mating occurs only once a year, with a maximum of two joeys being born in each pair.
Marsupials typically develop their offspring in an external pouch containing teats to which their newborn young (joeys) attach themselves for post uterine development.
The six to eight joeys have a pouch life of 40 days and are weaned at 70 days.
