The baby koala appeared outside of his mother Simpson’s pouch for the first time this morning after seven months of pregnancy.
The breeding came naturally between 10-year-old Simpson, and a male koala named Fulla.
The newborn koala was found healthy at birth, raising the total number of koala family in the northern zoo to ten.
The zoo launched a competition urging the public to help name the koala cub.
Simpson and Fulla, and other two koalas were sent from Australia's Taronga Zoo in an exchange with a Thai elephant from Chiang Mai Zoo under a cooperation programme of the two zoos since November 19, 2006.
