The expecting parents are officially at Taronga Zoo where they're getting very up close and personal with some new furry friends: Koalas!
Prince Harry, joined by his wife and Premier Gladys Berejiklian, seemed completely charmed by the marsupial.
The couple also met Lynx, a short legged echinda.
The couple ask if he is drooling because he's stressed, and are told no, he's "excited to see them!"
At the zoo, the couple opened a new Institute of Science & Learning.
Following their time at the zoo, the newlyweds will jet across the harbour for a walkabout at the Opera House.
The Duke and Duchess will then open a conservation research facility, before heading back to Admiralty House to celebrate the Sydney Invictus Games.
