It coincides with the opening of the zoo's new Animals of Australia habitat, which will start this month and completely revamp the previous elephant enclosure to emphasise the dangers that Australian species faces.
At the beginning of the summer, Belfast Zoo's two surviving Asian elephants, Dhunja and Yhetto, left for retirement in the Netherlands.
It is currently unknown if the zoo will ever again accept elephants. The need for upgrading in the zoo's arrangements for the housing and care of elephants was brought up in a recent assessment.
The Eastern Grey Kangaroo and the Red Necked Wallabies are among the first animals to arrive in Australia's natural environment, and they may be seen starting today.
Future upgrades, according to the zoo, will let guests to interact closely with a brand-new interaction space inside the habitat.
Education will be important because the new habitat will draw attention to the important role that zoos like Belfast, through its involvement in European Endangered Species Breeding Programs, play in the protection of numerous threatened and endangered Australian species.
