Prince Harry has opened the enhanced Anzac Memorial in Sydney's Hyde Park.
The Duke and Duchess of Sussex attended the ceremony on Saturday morning alongside the governor of NSW, retired general David Hurley, Prime Minister Scott Morrison and NSW Premier Gladys Berejiklian.
Harry, a former officer in the British Army, wore military dress uniform as he unveiled the plaque to open the extension which completes the memorial first opened by his great-great uncle Prince Henry in 1934.

General Hurley told the ceremony a public fund was established on the first anniversary of the Gallipoli landings to finance the construction of the memorial to honour the servicemen and women who died in the Great War.
"The memorial was completed as far as funds would allow in 1934 after a difficult period for fundraising, following the war and during the depression," he said.
The memorial extension, funded by the Commonwealth and NSW governments, is the centrepiece of the state's Centenary of Anzac commemorations to mark the 100th anniversary of the ending of the First World War this year.
The extension has been designed to enhance its role to support and provide services for veterans and their families, ensuring a public and a private place of contemplation, remembrance, education and reflection.

It features a major new artwork with more than 1700 soil samples from each NSW town, suburb and district given as a place of address by First World War enlistees in the region.
It also has new education spaces and exhibition areas and accommodated the Royal United Services Institute for defence and security studies library.
"All of this allows the memorial to tell the story of NSW' involvement with and for all Australians, in war, and in peacekeeping missions," General Hurley said.

"It honours those who have served and fosters ongoing scholarship and learning."
Harry and Meghan laid a wreath as did other dignitaries followed by a minute's silence and the Last Post.
Meghan wore a black, high-necked, full-skirted dress with buttons down the front and hat.
