Prince George joined his parents at Taronga Zoo for the opening of the bilby enclosure which is named in his honour.
In their final official engagement in Sydney for this Royal Tour, William and Kate left Admiralty House with their son.
The Duke joked in a speech given when the Cambridges first arrived in Australia last week: "I suspect George's first word might be 'bilby' - only because koala is harder to say. We really look forward to our time here together as a family."
The Duke and Duchess of Cambridge have celebrated Easter at a service in Sydney's St Andrew's Cathedral on the fifth day of their tour of Australia.
The royal couple were met by the Archbishop of Sydney, the Most Rev Dr Glenn Davies, when they arrived at the cathedral for the 65 minute long service.

The Duchess of Cambridge relegated her husband to the role of an onlooker when she turned down his offer to jump into the back seat - of a fighter jet.
Yesterday she suggested he try an alpaca toupee, and this morning she took control of a sophisticated fighter plane, sitting in the pilot's front seat.
The Duke had made an offer to his wife he believed she could not refuse, asking: "Do you fancy jumping in the back?" But the Duchess was not about to miss the opportunity to see for herself the multimillion-pound plane's cockpit.
The Duke and Duchess of Cambridge planted a tree of remembrance in honour of airforce members who gave their life at the Royal Australian Airforce Base at Amberley in Brisbane, Australia.
The Duke and Duchess of Cambridge have arrived at an airbase in Queensland.

The Duchess of Cambridge has thanked everyone who has welcomed her and her son George "so incredibly warmly" on their first visit to Australia.
Speaking at the children's hospice Bear Cottage she said of her trip:
"To be here as a family has been very special and we'll always remember it as such a happy memory. Thank you for inviting us here and for such a generous welcome."
The Duchess of Cambridge poked fun at her husband during their tour of Australia after she suggested that the perfect solution for his bald patch would be an alpaca toupee.
The royal couple met exhibitor Lyn Crejan, 67, at the prestigious Sydney Royal Easter Show, who showed Kate and William a tuft of alpaca wool - which was a similar shade of brown to the Duke's hair.
The Duchess, who wore a white Zimmermann dress, joked about her husband using it as a wig.
Ms Crejan, a farmer from the settlement of Glenn Innes in New South Wales, said: "The Prince was interested in the alpaca and as I showed it to them the Princess said he should put it on his head.
"She said, 'you need it more than me', and pointed to his head and he laughed."
The Duchess of Cambridge has thanked Australia for the warm welcome she and baby Prince George have received and said the visit "will always be remembered with fond and happy memories".
Kate, who was visiting a children's hospice in Sydney with William, praised many people including prime minister Tony Abbott and thousands of well-wishers who have greeted the Cambridges since their tour began a few days ago.
The Duchess toured Sydney's Bear Cottage - one of only two children's hospices in Australia - and praised the centre as a "haven" that was "inspirational".
Kate, who is royal patron of East Anglia's Children's Hospice (Each), said in a speech: "If I may, I would also like to take this opportunity to thank everyone who has welcomed me and George so incredibly warmly on our first visit.
"To be here together as a family has been very special and we will always remember it with fond and happy memories."
The Duchess added: "First class delivery of children's palliative care is life changing. When families are confronted with the shattering news that their children have a life limiting condition, their world can fall apart. It is at those times that professional support is imperative."
