Sydney's koala joey emerges from mom's pouch
Humphrey is estimated to be around eight months old, and is mother Willow's fifth joey.
Senior Koala Keeper, Laura Jones, said that Humphrey is doing well, and "is already beginning to attempt to eat eucalyptus leaves and is hanging on really tight to mum's back".
Koala joeys typically stay in their mother's pouch for up to six months, before they begin to emerge and attach themselves to their mother's back.
