The Duke and Duchess of Cambridge have joined a memorial parade in Canberra to mark Anzac Day.
William wore his military service medals to the ceremony, while Kate wore a Poppy brooch given to her by the wife of an Australian Victoria Cross holder.
The service falls on the final day of the royals' tour of the country.
The Duke and Duchess of Cambridge were up before dawn for a solemn remembrance of Australia's war dead.
The couple made an unannounced appearance in the darkness at the Australian War Memorial in Canberra for the early service marking Anzac Day - a national day of remembrance for the nation's fallen, veterans and those still serving.
With the Australian War Memorial lit up behind them, William and Kate quietly arrived at around 5am local time on Friday.
Kate, 32, in a cream scarf and black coat and black leather gloves, stood to William's right, her hands clasped in front of her as they listened to the early readings which were already under way.
The Duke of Cambridge has given a speech to the Australian parliament in Canberra, praising the country as a rising "economic power house" and giving thanks for the "warmth and generosity" shown to them during their tour.
On the penultimate day, he also mentioned Prince George's love for a large wombat toy received during the trip.

The Duke and Duchess of Cambridge were taken around Uluru, or Ayer's Rock, by local guides today, before watching the sunset at Australia's most iconic landmark - which was described by Kate described as "absolutely stunning."

ITV News Royal Correspondent Tim Ewart reports:
The Duke and Duchess of Cambridge have visited Australia's National Indigenous Training Academy as their tour of the country continues.
The visit to the school - which helps to train members of Australia's ethnic communities in the tourism and hospitality trades - will be followed by a traditional welcome at the Uluru Cultural Centre.
The royals - without Prince George, who is staying with his nanny in Canberra - will view an indigenous art display and later attend afternoon tea, given by the chief minister of the Northern Territory.
After tea, the Duke and Duchess will visit Uluru - also known as Ayers Rock - taking a short walk along its base in the company of a local guide.
Uluru is a world famous landmark - a huge mound of sandstone that stands almost 350 metres high and is more than two miles long and a mile wide.
After a day at the zoo it was a quick flight to the Australian capital for Prince George and his parents the Duke and Duchess of Cambridge.
After landing in Canberra the royals were met by the Governor-General of Australia Sir Peter Cosgrove and the Foreign Minister Julie Bishop.
Prince William strapped baby George into a child seat in their car before they were driven to Government House where they will spend the night.
Prince George joined his parents at Taronga Zoo for the opening of the bilby enclosure which is named in his honour.
In their final official engagement in Sydney for this Royal Tour, William and Kate left Admiralty House with their son.
The Duke joked in a speech given when the Cambridges first arrived in Australia last week: "I suspect George's first word might be 'bilby' - only because koala is harder to say. We really look forward to our time here together as a family."
The Duke and Duchess of Cambridge have celebrated Easter at a service in Sydney's St Andrew's Cathedral on the fifth day of their tour of Australia.
The royal couple were met by the Archbishop of Sydney, the Most Rev Dr Glenn Davies, when they arrived at the cathedral for the 65 minute long service.
