Tiger cubs Melati and Mya play at the National Zoo in Canberra, Australia, on Wednesday. The two animals born in the Dreamworld theme park on the Gold Coast earlier this year were recently relocated to the National Zoo where they will continue their work as ambassadors for the wild tiger conservation. Melati and Mya will take up permanent residency in the multi-award-winning Jamala Wildlife Lodge at the National Zoo.  EPA via Xinhua
