Touching down in Sydney there was an important question waiting for him from some elderly ladies in the 1,000-strong crowd that had assembled to greet him.
The second-in-line, who has been dating Kate Middleton for more than six years, was asked: "When are you getting married?"
But he side-stepped the query, with the words: "As I keep saying – wait and see."
Wills was visiting Redfern Community Centre in one of the city’s most deprived Aboriginal areas.
He was welcomed with a traditional Aboriginal dance and the burning of cleansing eucalyptus leaves on a bark tray, the fumes from which were wafted into his face by an elder.
Earlier the Prince was whisked off for a welcome lunch at Admiralty House, which enjoys stunning views of the Sydney Opera House. There he was introduced to local celebs, including Australian actress-turned-singer Deltra Goodrem.
The pretty blonde said she was thrilled to be meeting William, as she is a keen royalist.
"I have always respected and appreciated their lives and enormous experience," said the star, who is in a relationship with Westlife singer Brian McFadden.
During Wills' final day in New Zealand he had paid a rare public tribute to his mother Princess Diana.
And on a visit to a children's hospital he was asked if his affinity with sick youngsters was inherited from his late mother.
"I wouldn't say I was anywhere near her level," he replied. "She had a fantastic affinity with kids and with everyone. I just go and meet people and just enjoy their company. I like meeting people, so it helps."
