The Duke of Cambridge has praised Australia for being a "beacon of confidence" as thousands of Australians turned out to greet him and his family as they arrived in the country.
ITV News Royal Correspondent Tim Ewart reports:
William and Kate were met with cheers as they visited Sydney's iconic Opera House for a reception to mark the start of their 10-day tour of Australia.
The royal couple also posed for "selfies" with some of the waiting crowd members.
Meanwhile Prince George received a special gift from Australia's Governor-General - a cuddly wombat.
The eight-month-old prince is expected to make an appearance on Sunday when his parents take him to Sydney's Taronga Zoo where an enclosure housing bilbys - a rabbit-like marsupial - will be named after him.
William joked: "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."
