Royals commemorate Anzac Day
The Prime Minister, Governor-General and the Duke and Duchess of Cambridge lay wreaths at the Australian War Memorial.
Prince George, wearing a red sweater to combat the cooler temperatures, made his final public appearance on the tarmac, carried in his mother's arms as his parents said goodbye to dignitaries including Prime Minister Tony Abbott, his wife Margie, Bill Shorten and ACT chief minister Katy Gallagher.
The little prince let out a wail as they were farewelled on the tarmac.
Catherine and William paused briefly to wave to adoring fans who had gathered at the base before boarding the plane at the RAAF base in Fairbairn, marking the end of their Royal tour.
The Royal couple stopped and spoke briefly to Federal Police Officers who led their motorcade to the airport before boarding a RAAF plane.
The family is expected to make a stopover in Sydney before continuing their journey home.
Dozens of eager Royal watchers gathered and waved flags at the RAAF base in Fairbairn for a final glimpse of the Royals before they jetted off.
The Ferry family travelled from Melbourne to see the Duke and Duchess depart Canberra.
Janet and Patrick Ferry, along with their four young children, said it was exciting to get albeit a brief glimpse of the Royals.
Their nine-year-old daughter Teresa plans to lay a bouquet of flowers she had hoped to gift to Catherine at the National War Memorial.
"The kids wanted to see them and I think it's important because eventually William will be their king so it's important they get to have that connection," Mr Ferry said.
Matthew Sait, from the Australian Monarchist League, was in the crowd brandishing a poster urging their Royal Highnesses to "come back soon".
"It's been a popular visit and we expected it would be. Australians and Territorians love our Royal family," he said. "We love every opportunity we get to see them."
Self-confessed "die-hard" monarchist 17-year-old Emma Thoresen said she loved the Royals and was sad to see Catherine and William leave.
"It's sad but I'm sure they'll be glad to get home. They've had a really busy trip," she said.
"I love the Royals and it's a really good structure for our country to have a head of State who is not a politician."
She believed Australia had fallen in love with Catherine and William during their visit because they "were just such lovely and genuine people."
Sonia Bremstellar also braved the cooler temperatures with her three children, Tia, Nathan and Matty, to say farewell to the Royals.
"We saw them when they arrived and now we are seeing them off. The kids were very excited of course," she said.
"Matty has been waving his Aussie flag and yelling out 'bye bye George'. I think it's been fantastic they have been able to come and see what a fantastic country Australia is and also draw attention to a lot of really great causes."
