When is Meghan Markle's baby due

A beaming Meghan Markle looked remarkably unfatigued by a 22-hour flight as she walked out of Sydney's airport with Prince Harry on Monday for a rest day before they officially start a 16-day tour of Australia and the South Pacific.

"Their Royal Highnesses The Duke and Duchess of Sussex are very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019". The statement also thanked the public for the support they have received from around the world since their wedding in May.

The royal couple's trip Down Under is their only worldwide tour since they were married, apart from a two-day visit to Ireland. Meghan, wearing skinny black trousers and a black, burgundy trimmed coat, was smiling and clutching folders, while Harry gave a thumbs up to bystanders. They spent the day recovering from the flight and preparing for their first full day of engagements.

On October 16, Cosgrove who is Australia's Head of State, will give the couple an official welcome before their visit to Taronga Zoo and Sydney Opera House.

The tour coincides with the Invictus Games in Sydney which start on Saturday.

They will also visit New Zealand, Tonga and Fiji.

The tour coincides with the third Invictus Games, an worldwide sports competition Harry founded in 2014 for wounded veterans and members of the military, which kicks off Saturday.

The visit comes six months after Harry's father, Prince Charles, made his 16th official visit to Australia, primarily to open the 21st Commonwealth Games at Gold Coast city in Queensland.

Their baby will be a first cousin of Prince George, Princess Charlotte and Prince Louis - but will not be a prince or princess themselves unless the Queen steps in ahead of the birth.

Australian Prime Minister Scott Morrison, who took the top job in August after a backbench revolt ousted predecessor Malcolm Turnbull, is a constitutional monarchist.

The parents-to-be might have announced the news first to Meghan's mum Doria, seeing as she was in London last month, when her daughter Meghan hosted an outdoor reception at Kensington Palace to mark the launch of the new cookbook she helped bring to life.

Harry, 33, and Meghan, 37, have been invited by the governments of Australia and New Zealand, members of the Commonwealth.
