The Duke and Duchess of Cambridge arrived in Sydney today for the second half of their 19-day tour Down Under.

Prince William and Duchess Kate treated local dignitaries to a royal first upon their arrival in Australia's largest city, introducing them to their 8-month-old son, Prince George.

George - dressed in a white romper accented by embroidered sailboats - was alternatively carried by his mother and father as they descended their plane at Sydney Airport and greeted well-wishers and dignitaries that included Australian Prime Minister Tony Abbott.

Kate, 32, wore a Roksanda Ilincic Ryedale dress from the London-based designer's Spring/Summer 2014 collection that retails for around $1,500.

The vibrant yellow color of Kate's dress paid homage to Australia's national color but Prince William, 31, reportedly thought the dress reminded him of something else.

"William said I look like a banana," Kate reportedly told a well-wisher.

The crowds loved William and Kate as they posed in front of the Sydney Harbour Bridge while attending a reception at the Sydney Opera House. Even though the new parents left Prince George behind for the event, their son was not far from their minds.

"I suspect George's first word might be Bilby, only because Koala is harder to say," Prince William said in a speech, referring to the rabbit-like animals indigenous and iconic to Australia.

It was not a Bilby but a stuffed wombat, another well-known Australian animal, that Prince George was gifted by Australia's Governor-General on Wednesday. George greeted the stuffed animal with a smile, as did his father, Prince William, who was nicknamed 'wombat' by his mother, Princess Diana.

Prince William spoke lovingly of his late mother, Diana, who gave her son the nickname when she, Prince William and his father, Prince Charles, traveled to Australia 31 years ago.

"My mother's deep affection for Australia - which you were so kind to reciprocate - needs no reminder," William said.

Later this week, William and Kate will travel to Ayers Rock, the iconic sandstone monument that Prince Charles and Princess Diana visited as well.
