During a walkabout in Sydney, the royals stopped for self-portraits with excited fans who had gathered for a glimpse of the couple.
Nina Kiwarkis, a woman awaiting a heart and lung transplant, was lucky enough to get a selfie with both William and Kate. "I thought William would say no but he didn’t. He wished me well," she said afterwards.
Chloe Skafte, a 19-year-old student, took a selfie with the Duchess after giving her a bunch of flowers.
Earlier on in the tour, during a walkabout in Christchurch, Kate was spotted high-fiving a youngster while laughing at the camera. The snap was then retweeted thousands of times with the hashtag #besteverselfie.
Kate, William and baby George were given a rockstar-like welcome when they arrived in Australia for the first time as a family.
They were greeted to cheers as they stepped off the plane and thousands of well-wishers lined the Sydney Harbour foreshore on Thursday afternoon, in the shadow of the Opera House.
