Prince William and Kate Middleton, accompanied by their son Prince George, arrived in Sydney late Wednesday afternoon.
William, Kate and George flew from New Zealand to Australia, on the second leg of their three-week Pacific trip. They will now spend nine days touring the country.
Eight-month-old George, who is on his first tour abroad along with his parents, stole the limelight at Sydney airport as he did at Wellington airport in New Zealand.
Dressed in an all white jumper, George was carried by his mother as the royal family disembarked from the plane. But the Duke of Cambridge held his son outwards later when the royal couple were greeted by the Governor-General of Australia Peter Cosgrove and his wife Lynne Cosgrove.
After arrival in Sydney, the Duke and Duchess of Cambridge were given a reception at the Sydney Opera House by the Governor of New South Wales Marie Bashir and her husband Nicholas Shehadie.
William and Kate will be based in Sydney, from where they are expected to visit Blue Mountains, Brisbane, Uluru, Adelaide, and Canberra.
Their first visit outside Sydney will be on Thursday to an area of the Blue Mountains in New South Wales badly hit by bushfires in October 2013.
Kate's first dress honours Australia
The Duchess touched down in Sydney honouring the nation by donning a Roksanda Ilincic dress in yellow, one of Australia's national colours.
Kate wore pearl drop earrings and completed her ensemble with nude stilettos. Prince William was dressed in a navy suit.
Both Kate and little George had an in-flight dress change as they flew from Wellington on Wednesday morning in different outfits.
The Duchess wore a navy Rebecca Taylor outfit, matching William's navy suit for their morning and last engagement in New Zealand which was a visit to the Royal New Zealand Police College in Wellington.
The royal couple were joined by George while departing the country from Wellington airport where the future heir wore a dark ensemble and a white woollen jumper.
