LONDON (AFP) - Baby Prince George was heading from Britain to New Zealand and Australia on Sunday, with parents Prince William and his wife Catherine taking the eight-month-old on his first ever tour.
Prince George, third in line to the throne of all three countries, follows in the footsteps of his father who travelled Down Under with his parents Prince Charles and Diana in 1983 aged nine months.
The three-week royal tour by Prince William, 31, his wife Kate, 32, and Prince George will be one of the first times the young prince has been seen in public since his birth on July 22 last year.
On March 30 palace officials issued a photo of the chubby prince, wearing a sweater with his name on, alongside his parents and their dog Lupo posing in the window of their Kensington Palace residence in London.
The symbolism of the trip is clear, with Prince George also being directly in line to become king of Australia and New Zealand after grandfather Charles and then William.
Prince George will only be taken to a few specific engagements throughout the trip, their Kensington Palace residence said.
In New Zealand, the royal couple will start their visit in Wellington on Monday with a ceremonial welcome including a Maori dance, and inspect a guard of honour.
Prince George could have some playmates on Wednesday when William and Kate attend a reception at Government House in Wellington with new mothers and their toddlers.
On Thursday they travel to Blenheim for a wreath laying session honouring New Zealand soldiers killed in World War I, which broke out 100 years ago.
They will also meet Prime Minister John Key and attend a state reception where William will unveil a portrait of Queen Elizabeth II.
The couple are in Auckland on Friday, Hamilton and Cambridge on Saturday, Dunedin and Queenstown on Sunday, where they will brave the Shotover Jet - a high-speed white-water thrill ride down a river canyon, and Christchurch on April 14, where they will pay their respects to victims of the 2011 earthquake.
Australia hosts the couple from April 16 when they arrive in Sydney, before travelling on to the Blue Mountains on April 17, Brisbane on April 19, Uluru (Ayers Rock) on April 22, Adelaide on April 23 and Canberra on April 24 and 25, before flying home.
Specific events on the tour will celebrate Australia's and New Zealand's achievements in the fields of technology, tourism, sports and the creative arts.
Their 11-person entourage will include a hairdresser and a recently-appointed Spanish nanny. They fly to and from London on scheduled flights.
Prince William's private secretary Miguel Head told reporters in March that the couple had put in a lot of planning for the visit, which will be Kate's first to either country.
"Taking a nine-month-old on a royal tour is not a first," but has not happened for a long time, said Mr Head.
"So there has been much to think about - as any new parent travelling long distance will recognise."
Prince William was nine months old when he made his first trip to Australia and New Zealand. Charles and his first wife Diana, who died in a car crash in Paris in 1997, took him on their tour in March and April 1983.
The upcoming visit will allow William and Kate to do what they wanted to do "above all else: meet New Zealanders and Australians", Head added.
William and Kate were treated like celebrities when they visited Canada months after their wedding in 2011, while in 2012 they toured Singapore, Malaysia, the Solomon Islands and Tuvalu on behalf of Queen Elizabeth to mark her 60 years on the throne.
