The 34-year-old Duke and the 37-year-old Duchess of Sussex arrived in Sydney on a Qantas Airways flight at 7 a.m., and the two were all smiles as they were flanked by a large crew of aides and officials.
A heavy police presence greeted the couple at Sydney Airport, ready to whisk the Royals away to Admiralty House, the Governor-General's Sydney residence.
Just weeks ago the palace revealed the royal couple's full itinerary, setting out every detail of their visits to New South Wales, Queensland and Victoria, before they go on a visit to Fiji, Tonga and New Zealand.
Meghan Markle is all about her girl squad, even when she's traveling across the world for a major royal tour.
Despite the almost 20-hour flight from London to Australia, both royals looked fresh-faced and happy to kick off their 16-day tour of the continent, which will take them across Australia, Fiji, Tonga and New Zealand.
The Duke and Duchess of Sussex have arrived at Admiralty House in Sydney for a day of rest before they begin an intense 16-days of engagements across four countries.
They are beginning their official engagements in Sydney tomorrow, including meeting representatives for the Invictus Games and visiting Taronga Zoo.
The Olympics-style sporting event was founded by Prince Harry in 2014, for sick and injured veterans.
Prince Harry will launch the fourth Invictus Games in Sydney on Friday, and attend the opening and closing ceremonies.
Despite Harry and Meghan's arrival, it appeared most royal family fans had not woken to welcome the couple into Australia, with Sydney's International Airport terminal appearing completely empty this morning.
Harry and Meghan will also head to New Zealand, Fiji and Tonga.
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.
