Britain's Prince William and Duchess Catherine have reportedly found a new nanny for young Prince George.

The couple are thought to have recruited a new child-minder to look after their tot after their current nanny Jessie Webb, 71, who previously looked after William when he was a child, gave notice last month.

According to US website The Daily Beast, the new nanny is a young English woman in her twenties who is well connected within royal society and "established" with the family at Kensington Palace.

Seven-month-old George will accompany William, 31, and Catherine, 32, during their 19-day royal visit to Australia and New Zealand next month.

Royal press secretary Miguel Head appeared to confirm the recruitment of a new nanny in an itinerary for the trip, which was released to media recently.

The release reads: "The party is similar in size to recent overseas visits undertaken by Their Royal Highnesses. It consists of me and the Duchess's Private Secretary, Rebecca Deacon, three press officers, a Tour Secretary, a Personal Assistant, a Hairdresser and an Orderly to help manage the logistics. Sir David Manning will also accompany Their Royal Highnesses throughout. A new addition to the party is, of course, Prince George's nanny."

William, Catherine and George will visit Australia and New Zealand between April 7 and April 25.

Among the activities the royal couple will enjoy include a game of cricket and yacht racing.
